Background/Aims
Epidemiological data on steroid use in South Korean patients with inflammatory bowel disease (IBD) are limited. We documented the steroid use patterns in these patients, and whether physician education on appropriate steroid use affected these patterns.
Methods
ACTION was an observational cohort study conducted in adults (≥19 years) with IBD. A retrospective chart review was performed at baseline (cohort 1) and 1 year after physician training (cohort 2). Eligible cases with excessive or inappropriate steroid use were identified, along with any associated risk factors.
Results
Data were collected during May 2018-July 2019 from patients with Crohn’s disease (CD) and ulcerative colitis (UC) in cohort 1 (n=1,685) and cohort 2 (n=1,649). At baseline, 155 patients (9.2%) had received steroids within the previous 12 months, 46 (29.7%) of whom had used steroids excessively, 16 (34.8%) of these having inappropriately used excessive steroids. Although steroid exposure was similar in cohort 1 (9.2%) and cohort 2 (9.7%), the latter comprised fewer excessive steroid users (20.0% vs. 29.7%). Severe disease was associated with excessive steroid use in cases with UC, but not with CD.
Conclusions
Although, overall steroid use was relatively low in South Korean patients with IBD, one-third of steroid users used them excessively, and one-third among these used excessive steroids inappropriately. High disease activity was the main risk factor for excessive steroid use which may potentially be reduced by physician education, especially in cases with UC. Active screening to minimize excessive and inappropriate steroid use through physician education should be considered.

Clinical outcomes and predictors of response for adalimumab in patients with moderately to severely active ulcerative colitis: a KASID prospective multicenter cohort study: Seung Yong Shin, Soo Jung Park, Young Kim, Jong Pil Im, Hyo Jong Kim, Kang-Moon Lee, Ji Won Kim, Sung-Ae Jung, Jun Lee, Sang-Bum Kang, Sung Jae Shin, Eun Sun Kim, You Sun Kim, Tae Oh Kim, Hyun-Soo Kim, Dong Il Park, Hyung Kil Kim, Eun Soo Kim, Young-Ho Kim, Do Hyun Kim, Dennis Teng, Jong-Hwa Kim, Wonyong Kim, Chang Hwan Choi, on behalf of the IBD Research Group of the Korean Association for the Study of Intestinal Diseases; Intest Res 2022;20(3):350-360. Published online July 23, 2021; DOI: https://doi.org/10.5217/ir.2021.00049

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
This study assessed the efficacy and safety of adalimumab (ADA) and explored predictors of response in Korean patients with ulcerative colitis (UC).
Methods
A prospective, observational, multicenter study was conducted over 56 weeks in adult patients with moderately to severely active UC who received ADA. Clinical response, remission, and mucosal healing were assessed using the Mayo score.
Results
A total of 146 patients were enrolled from 17 academic hospitals. Clinical response rates were 52.1% and 37.7% and clinical remission rates were 24.0% and 22.0% at weeks 8 and 56, respectively. Mucosal healing rates were 39.0% and 30.1% at weeks 8 and 56, respectively. Prior use of anti-tumor necrosis factor-α (anti-TNF-α) did not affect clinical and endoscopic responses. The ADA drug level was significantly higher in patients with better outcomes at week 8 (P<0.05). In patients with lower endoscopic activity, higher body mass index, and higher serum albumin levels at baseline, the clinical response rate was higher at week 8. In patients with lower Mayo scores and C-reactive protein levels, clinical responses, and mucosal healing at week 8, the clinical response rate was higher at week 56. Serious adverse drug reactions were identified in 2.8% of patients.
Conclusions
ADA is effective and safe for induction and maintenance in Korean patients with UC, regardless of prior anti-TNF-α therapy. The ADA drug level is associated with the efficacy of induction therapy. Patients with better short-term outcomes were predictive of those with an improved long-term response.

IBD

Perspectives of East Asian patients and physicians on complementary and alternative medicine use for inflammatory bowel disease: results of a cross-sectional, multinational study: Eun Soo Kim, Chung Hyun Tae, Sung-Ae Jung, Dong Il Park, Jong Pil Im, Chang Soo Eun, Hyuk Yoon, Byung Ik Jang, Haruhiko Ogata, Kayoko Fukuhara, Fumihito Hirai, Kazuo Ohtsuka, Jing Liu, Qian Cao, on behalf of the Clinical Research Committee of the Asian Organization for Crohn’s and Colitis; Intest Res 2022;20(2):192-202. Published online April 29, 2022; DOI: https://doi.org/10.5217/ir.2020.00150

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Complementary and alternative medicine (CAM) is prevalent in East Asia. However, information on CAM in East Asian patients with inflammatory bowel disease (IBD) is scarce. We aimed to profile the prevalence and pattern of CAM use among East Asian IBD patients and to identify factors associated with CAM use. We also compared physicians’ perspectives on CAM.
Methods
Patients with IBD from China, Japan, and South Korea were invited to complete questionnaires on CAM use. Patient demographic and clinical data were collected. Logistic regression analysis was applied for predictors of CAM use. Physicians from each country were asked about their opinion on CAM services or products.
Results
Overall, 905 patients with IBD participated in this study (China 232, Japan 255, and South Korea 418). Approximately 8.6% of patients with IBD used CAM services for their disease, while 29.7% of patients sought at least 1 kind of CAM product. Current active disease and Chinese or South Korean nationality over Japanese were independent predictors of CAM use. Chinese doctors were more likely to consider CAM helpful for patients with IBD than were Japanese and South Korean doctors.
Conclusions
In 8.6% and 29.7% of East Asian patients with IBD used CAM services and products, respectively, which does not differ from the prevalence in their Western counterparts. There is a significant gap regarding CAM usage among different Asian countries, not only from the patients’ perspective but also from the physicians’ point of view.

Inflammatory Bowel Diseases

Long-term outcomes of infliximab in a real-world multicenter cohort of patients with acute severe ulcerative colitis: Shin Ju Oh, Ga Young Shin, Hosim Soh, Jae Gon Lee, Jong Pil Im, Chang Soo Eun, Kang-Moon Lee, Dong Il Park, Dong Soo Han, Hyo Jong Kim, Chang Kyun Lee; Intest Res 2021;19(3):323-331. Published online August 18, 2020; DOI: https://doi.org/10.5217/ir.2020.00039

Abstract PDF PubReader ePub

Background/Aims
Infliximab (IFX) has proven effective as rescue therapy in steroid-refractory acute severe ulcerative colitis (ASUC), however, the long-term real-world data are scarce. Our study aimed to assess the long-term treatment outcomes of IFX in a real-life cohort.
Methods
We established a multicenter retrospective cohort of hospitalized patients with ASUC, who met Truelove and Witt’s criteria and received intravenous corticosteroid (IVCS) or IFX during index hospitalization between 2006 and 2016 in 5 university hospitals in Korea. The cohort was systematically followed up until colectomy, death or last follow-up visit.
Results
A total of 296 patients were followed up for a mean of 68.9 ± 44.0 months. During index hospitalization, 49 patients were treated with IFX; as rescue therapy for IVCS failure in 37 and as first-line medical therapy for ASUC in 12. All patients treated with IFX avoided colectomy during index hospitalization. The cumulative rates of rehospitalization and colectomy were 20.4% and 6.1% at 3 months and 39.6% and 18.8% at the end of follow-up, respectively. Patients treated with IFX presented with significantly shorter colectomy-free survival than IVCS responders (P= 0.04, log-rank test). Both cytomegalovirus colitis and Clostridioides difficile infection (CDI) were the significant predictors of colectomy in the overall study cohort (hazard ratios of 6.57 and 4.61, respectively). There were no fatalities.
Conclusions
Our real-world cohort study demonstrated that IFX is an effective therapeutic option in Korean patients with ASUC, irrespective of IFX indication. Aggressive vigilance for cytomegalovirus colitis and CDI is warranted for hospitalized patients with ASUC.

Abstract PDF PubReader ePub

Background/Aims
PF-00547659 is a monoclonal antibody against human mucosal addressin cell adhesion molecule-1 (MAdCAM-1) that prevents the binding of α4β7+ lymphocytes to MAdCAM-expressing sites in the gastrointestinal tract with high affinity and selectivity, and is being developed for the treatment of Crohn’s disease (CD).
Methods
OPERA is a randomized, multicenter, double-blind, placebo-controlled study to investigate the efficacy, safety, and pharmacokinetics of PF-00547659 following subcutaneous administration in subjects with active CD, a history of failure or intolerance to anti-tumor necrosis factor and/or immunosuppressants, high-sensitivity C-reactive protein > 3.0 mg/L, and ulcers on colonoscopy. The primary endpoint was Crohn’s Disease Activity Index-70 response at week 8 or 12. Subpopulation analyses for Asian subjects were performed as some differences are observed in genetics and clinical phenotypes in Asian CD patients compared with Western patients.
Results
In this study, 265 CD subjects were randomized, with a subpopulation of 21 subjects (8 Japanese and 13 Korean) defined as the Asian population. In the overall and Asian populations; PF-00547659 was pharmacologically active as evidenced by soluble MAdCAM and circulating β7+ central memory CD4+ T-lymphocytes, although no clear evidence of efficacy was observed in any clinical endpoints; pharmacokinetics of PF-00547659 in the Asian subpopulation was generally comparable to the overall population; and the safety profile of PF-00547659 appeared acceptable up to 12 weeks of treatment.
Conclusions
In the overall and Asian populations, efficacy of PF-00547659 could not be demonstrated using any clinical endpoints compared with placebo. Pharmacokinetics and safety of PF-00547659 were generally comparable. Further studies with larger numbers of patients are required to confirm our results. (Trial Registration Number: NCT01276509)

Abstract PDF PubReader ePub

The Asia-Pacific Working Group on inflammatory bowel disease (IBD) was established in Cebu, Philippines, under the auspices of the Asian Pacific Association of Gastroenterology with the goal of improving IBD care in Asia. This consensus is carried out in collaboration with Asian Organization for Crohn’s and Colitis. With biologic agents and biosimilars becoming more established, it is necessary to conduct a review on existing literature and establish a consensus on when and how to introduce biologic agents and biosimilars in the conjunction with conventional treatments for ulcerative colitis (UC) and Crohn’s disease (CD) in Asia. These statements also address how pharmacogenetics influence the treatments of UC and CD and provide guidance on response monitoring and strategies to restore loss of response. Finally, the review includes statements on how to manage treatment alongside possible hepatitis B and tuberculosis infections, both common in Asia. These statements have been prepared and voted upon by members of IBD workgroup employing the modified Delphi process. These statements do not intend to be all-encompassing and future revisions are likely as new data continue to emerge.

Colorectal neoplasia

Development and validation of a scoring system for advanced colorectal neoplasm in young Korean subjects less than age 50 years: Ji Yeon Kim, Sungkyoung Choi, Taesung Park, Seul Ki Kim, Yoon Suk Jung, Jung Ho Park, Hong Joo Kim, Yong Kyun Cho, Chong Il Sohn, Woo Kyu Jeon, Byung Ik Kim, Kyu Yong Choi, Dong Il Park; Intest Res 2019;17(2):253-264. Published online November 20, 2018; DOI: https://doi.org/10.5217/ir.2018.00062

Abstract PDF PubReader ePub

Background/Aims
Colorectal cancer incidence among patients aged ≤50 years is increasing. This study aimed to develop and validate an advanced colorectal neoplasm (ACRN) screening model for young adults aged <50 years in Korea.
Methods
This retrospective cross-sectional study included 59,575 consecutive asymptomatic Koreans who underwent screening colonoscopy between 2003 and 2012 at a single comprehensive health care center. Young Adult Colorectal Screening (YCS) score was developed as an optimized risk stratification model for ACRN using multivariate analysis and was internally validated. The predictive power and diagnostic performance of YCS score was compared with those of Asia-Pacific Colorectal Screening (APCS) and Korean Colorectal Screening (KCS) scores.
Results
41,702 and 17,873 subjects were randomly allocated into the derivation and validation cohorts, respectively, by examination year. ACRN prevalence was 0.9% in both cohorts. YCS score comprised sex, age, alcohol, smoking, obesity, glucose metabolism abnormality, and family history of CRC, with score ranges of 0 to 10. In the validation cohort, ACRN prevalence was 0.6% in the low-risk tier (score, 0–4), 1.5% in the moderate-risk tier (score, 5–7), and 3.4% in the high-risk tier (score, 8–10). ACRN risk increased 2.5-fold (95%CI, 1.8–3.4) in the moderate-risk tier and 5.8-fold (95%CI, 3.4–9.8) in the high-risk tier compared with the low-risk tier. YCS score identified better balanced accuracy (53.9%) than APCS (51.5%) and KCS (50.7%) scores and had relatively good discriminative power (area under the curve=0.660).
Conclusions
YCS score based on clinical and laboratory risk factors was clinically effective and beneficial for predicting ACRN risk and targeting screening colonoscopy in adults aged <50 years.

Three-year colonoscopy surveillance after polypectomy in Korea: a Korean Association for the Study of Intestinal Diseases (KASID) multicenter prospective study: Won Seok Choi, Dong Soo Han, Chang Soo Eun, Dong Il Park, Jeong-Sik Byeon, Dong-Hoon Yang, Sung-Ae Jung, Sang Kil Lee, Sung Pil Hong, Cheol Hee Park, Suck-Ho Lee, Jeong-Seon Ji, Sung Jae Shin, Bora Keum, Hyun Soo Kim, Jung Hye Choi, Sin-Ho Jung; Intest Res 2018;16(1):126-133.

Abstract PDF PubReader ePub

Background/Aims

Colonoscopic surveillance is currently recommended after polypectomy owing to the risk of newly developed colonic neoplasia. However, few studies have investigated colonoscopy surveillance in Asia. This multicenter and prospective study was undertaken to assess the incidence of advanced adenoma based on baseline adenoma findings at 3 years after colonoscopic polypectomy.

Methods

A total of 1,323 patients undergoing colonoscopic polypectomy were prospectively assigned to 3-year colonoscopy surveillance at 11 tertiary endoscopic centers. Relative risks for advanced adenoma after 3 years were calculated according to baseline adenoma characteristics.

Results

Among 1,323 patients enrolled, 387 patients (29.3%) were followed up, and the mean follow-up interval was 31.0±9.8 months. The percentage of patients with advanced adenoma on baseline colonoscopy was higher in the surveillance group compared to the non-surveillance group (34.4% vs. 25.7%). Advanced adenoma recurrence was observed in 17 patients (4.4%) at follow-up. The risk of advanced adenoma recurrence was 2 times greater in patients with baseline advanced adenoma than in those with baseline non-advanced adenoma, though the difference was not statistically significant (6.8% [9/133] vs. 3.1% [8/254], P=0.09). Advanced adenoma recurrence was observed only in males and in subjects aged ≥50 years. In contrast, adenoma recurrence was observed in 187 patients (48.3%) at follow-up. Male sex, older age (≥50 years), and multiple adenomas (≥3) at baseline were independent risk factors for adenoma recurrence.

Conclusions

A colonoscopy surveillance interval of 3 years in patients with baseline advanced adenoma can be considered appropriate.

Abstract PDF PubReader ePub

Because anti-tumor necrosis factor (anti-TNF) therapy has become increasingly popular in many Asian countries, the risk of developing active tuberculosis (TB) among anti-TNF users may raise serious health problems in this region. Thus, the Asian Organization for Crohn's and Colitis and the Asia Pacific Association of Gastroenterology have developed a set of consensus statements about risk assessment, detection and prevention of latent TB infection, and management of active TB infection in patients with inflammatory bowel disease (IBD) receiving anti-TNF treatment. Twenty-three consensus statements were initially drafted and then discussed by the committee members. The quality of evidence and the strength of recommendations were assessed by using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Web-based consensus voting was performed by 211 IBD specialists from 9 Asian countries concerning each statement. A consensus statement was accepted if at least 75% of the participants agreed. Part 2 of the statements comprised 3 parts: management of latent TB in preparation for anti-TNF therapy, monitoring during anti-TNF therapy, and management of an active TB infection after anti-TNF therapy. These consensus statements will help clinicians optimize patient outcomes by reducing the morbidity and mortality related to TB infections in patients with IBD receiving anti-TNF treatment.

Abstract PDF PubReader ePub

Background/Aims

Colorectal cancer (CRC) screening using stool DNA was recently found to yield good detection rates. A multi-target stool DNA test (Cologuard®, Exact Sciences), including methylated genes has been recently approved by the U.S. Food and Drug Administration. The aim of this study was to validate these aberrantly methylated genes as stool-based DNA markers for detecting CRC and colorectal advanced adenoma (AA) in the Korean population.

Methods

A single-center study was conducted in 36 patients with AA; 35 patients with CRC; and 40 endoscopically diagnosed healthy controls using CRC screening colonoscopy. The methylation status of the SFRP2, TFPI2, NDRG4, and BMP3 promoters was investigated blindly using bisulfate-modified stool DNA obtained from 111 participants. Methylation status was investigated by methylation-specific polymerase chain reaction.

Results

Methylated SFRP2, TFPI2, NDRG4, and BMP3 promoters were detected in 60.0%, 31.4%, 68.8%, and 40.0% of CRC samples and in 27.8%, 27.8%, 27.8%, and 33.3% of AA samples, respectively. The sensitivities obtained using 4 markers to detect CRC and AA were 94.3% and 72.2%, respectively. The specificity was 55.0%.

Conclusions

Our results demonstrate that the SFRP2, TFPI2, NDRG4, and BMP3 promoter methylation analysis of stool sample DNA showed high sensitivity but low specificity for detecting CRC and AA. Because of the low specificity, 4 methylated markers might not be sufficient for CRC screening in the Korean population. Further large-scale studies are required to validate the methylation of these markers in the Asian population and to find new markers for the Asian population.

Miss rate of colorectal neoplastic polyps and risk factors for missed polyps in consecutive colonoscopies: Nam Hee Kim, Yoon Suk Jung, Woo Shin Jeong, Hyo-Joon Yang, Soo-Kyung Park, Kyuyong Choi, Dong Il Park; Intest Res 2017;15(3):411-418.

Background/Aims

Colonoscopic polypectomy is the best diagnostic and therapeutic tool to detect and prevent colorectal neoplasms. However, previous studies have reported that 17% to 28% of colorectal polyps are missed during colonoscopy. We investigated the miss rate of neoplastic polyps and the factors associated with missed polyps from quality-adjusted consecutive colonoscopies.

Methods

We reviewed the medical records of patients who were found to have colorectal polyps at a medical examination center of the Kangbuk Samsung Hospital between March 2012 and February 2013. Patients who were referred to a single tertiary academic medical center and underwent colonoscopic polypectomy on the same day were enrolled in our study. The odds ratios (ORs) associated with polyp-related and patient-related factors were evaluated using logistic regression analyses.

Results

A total of 463 patients and 1,294 neoplastic polyps were analyzed. The miss rates for adenomas, advanced adenomas, and carcinomas were 24.1% (312/1,294), 1.2% (15/1,294), and 0% (0/1,294), respectively. Flat/sessile-shaped adenomas (adjusted OR, 3.62; 95% confidence interval [CI], 2.40–5.46) and smaller adenomas (adjusted OR, 5.63; 95% CI, 2.84– 11.15 for ≤5 mm; adjusted OR, 3.18; 95% CI, 1.60–6.30 for 6–9 mm, respectively) were more frequently missed than pedunculated/sub-pedunculated adenomas and larger adenomas. In patients with 2 or more polyps compared with only one detected (adjusted OR, 2.37; 95% CI, 1.55–3.61 for 2–4 polyps; adjusted OR, 11.52; 95% CI, 4.61–28.79 for ≥5 polyps, respectively) during the first endoscopy, the risk of missing an additional polyp was significantly higher.

Conclusions

One-quarter of neoplastic polyps was missed during colonoscopy. We encourage endoscopists to detect smaller and flat or sessile polyps by using the optimal withdrawal technique.

Determining the optimal surveillance interval after a colonoscopic polypectomy for the Korean population?: Jung Lok Lee, Jae Myung Cha, Hye Min Lee, Jung Won Jeon, Min Seob Kwak, Jin Young Yoon, Hyun Phil Shin, Kwang Ro Joo, Joung Il Lee, Dong Il Park; Intest Res 2017;15(1):109-117.

Abstract PDF PubReader ePub

Background/Aims

Western surveillance strategies cannot be directly adapted to the Korean population. The aim of this study was to estimate the risk of metachronous neoplasia and the optimal surveillance interval in the Korean population.

Methods

Clinical and pathological data from index colonoscopy performed between June 2006 and July 2008 and who had surveillance colonoscopies up to May 2015 were compared between low- and high-risk adenoma (LRA and HRA) groups. The 3- and 5-year cumulative risk of metachronous colorectal neoplasia in both groups were compared.

Results

Among 895 eligible patients, surveillance colonoscopy was performed in 399 (44.6%). Most (83.3%) patients with LRA had a surveillance colonoscopy within 5 years and 70.2% of patients with HRA had a surveillance colonoscopy within 3 years. The cumulative risk of metachronous advanced adenoma was 3.2% within 5 years in the LRA group and only 1.7% within 3 years in the HRA group. The risk of metachronous neoplasia was similar between the surveillance interval of <5 and ≥5 years in the LRA group; however, it was slightly higher at surveillance interval of ≥3 than <3 years in the HRA group (9.4% vs. 2.4%). In multivariate analysis, age and the ≥3-year surveillance interval were significant independent risk factors for metachronous advanced adenoma (P=0.024 and P=0.030, respectively).

Conclusions

Patients had a surveillance colonoscopy before the recommended guidelines despite a low risk of metachronous neoplasia. However, the risk of metachronous advanced adenoma was increased in elderly patients and those with a ≥3-year surveillance interval.

Abstract PDF Supplementary Material PubReader ePub

Crohn's disease (CD) is a chronic, progressive, and disabling inflammatory bowel disease (IBD) with an uncertain etiopathogenesis. CD can involve any site of the gastrointestinal tract from the mouth to the anus, and is associated with serious complications, such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower compared with those in Western countries, but they have been rapidly increasing during the recent decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies have been applied for the treatment of this disease. Concerning CD management, there have been substantial discrepancies among clinicians according to their personal experience and preference. To suggest recommendable approaches to the diverse problems of CD and to minimize the variations in treatment among physicians, guidelines for the management of CD were first published in 2012 by the IBD Study Group of the Korean Association for the Study of Intestinal Diseases. These are the revised guidelines based on updated evidence, accumulated since 2012. These guidelines were developed by using mainly adaptation methods, and encompass induction and maintenance treatment of CD, treatment based on disease location, treatment of CD complications, including stricture and fistula, surgical treatment, and prevention of postoperative recurrence. These are the second Korean guidelines for the management of CD and will be continuously revised as new evidence is collected.

Abstract PDF PubReader ePub

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by a relapsing and remitting course. The direct and indirect costs of the treatment of UC are high, and the quality of life of patients is reduced, especially during exacerbation of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies, including biologics, are currently used for the management of UC. However, many challenging issues exist, which sometimes lead to differences in practice between clinicians. Therefore, the IBD study group of the Korean Association for the Study of Intestinal Diseases established the first Korean guidelines for the management of UC in 2012. This is an update of the first guidelines. It was generally made by the adaptation of several foreign guidelines as was the first edition, and encompasses treatment of active colitis, maintenance of remission, and indication of surgery for UC. The specific recommendations are presented with the quality of evidence and classification of recommendations.

Comparison of the efficacy of disinfectants in automated endoscope reprocessors for colonoscopes: tertiary amine compound (Sencron2®) versus ortho-phthalaldehyde (Cidex®OPA): Hyun Il Seo, Dae Sung Lee, Eun Mi Yoon, Min-Jung Kwon, Hyosoon Park, Yoon Suk Jung, Jung Ho Park, Chong Il Sohn, Dong Il Park; Intest Res 2016;14(2):178-182. Published online April 27, 2016; DOI: https://doi.org/10.5217/ir.2016.14.2.178

Abstract PDF PubReader ePub

Background/Aims

To prevent the transmission of pathogens by endoscopes, following established reprocessing guidelines is critical. An ideal reprocessing step is simple, fast, and inexpensive. Here, we evaluated and compared the efficacy and safety of two disinfectants, a tertiary amine compound (TAC) and ortho-phthalaldehyde (OPA).

Methods

A total of 100 colonoscopes were randomly reprocessed using two same automated endoscope reprocessors, according to disinfectant. The exposure time was 10 minutes for 0.55% OPA (Cidex® OPA, Johnson & Johnson) and 5 minutes for 4% TAC (Sencron2®, Bab Gencel Pharma & Chemical Ind. Co.). Three culture samples were obtained from each colonoscope after reprocessing.

Results

A total of nine samples were positive among the 300 culture samples. The positive culture rate was not statistically different between the two groups (4% for OPA and 2% for TAC, P=0.501). There were no incidents related to safety during the study period.

Conclusions

TAC was non-inferior in terms of reprocessing efficacy to OPA and was safe to use. Therefore, TAC seems to be a good alternative disinfectant with a relatively short exposure time and is also less expensive than OPA.

Current status of biosimilars in the treatment of inflammatory bowel diseases: Dong Il Park; Intest Res 2016;14(1):15-20. Published online January 26, 2016; DOI: https://doi.org/10.5217/ir.2016.14.1.15

Abstract PDF PubReader ePub

Introduction of biological therapies have led to dramatic changes in the management of debilitating immune-mediated inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease. However, the long term use of these agents may be very expensive, placing a significant burden on National Healthcare Systems. The development of first biosimilar to infliximab, CT-P13 (Remsima; Celltrion Inc., Incheon, Korea and Inflextra; Hospiral, Lake Forest, Illinois, USA) has become another way to decrease the medical care cost and increase patient treatment option, but, actual equivalence of efficacy and safety of CT-P13 was investigated in rheumatic diseases only. The extrapolation of outcome from rheumatic trials to IBD and the interchangeability of CT-P13 with infliximab have come to be a matter of concern. Two recent retrospective studies reported the similarity of CT-P13 in terms of efficacy and safety. Infliximab biosimilars may be promising new treatment options for IBD patients, however, well-designed, prospective randomized non-inferiority trials should be needed to confidently integrate infliximab biosimilars into IBD treatment.

Background/Aims

Quality of life is closely related to anemia in patients with inflammatory bowel disease (IBD). Several studies have reported on anemia in patients with IBD in Western countries. This study investigated the prevalence and clinical characteristics of anemia in Korean patients with IBD.

Methods

We reviewed the medical records of 92 patients with ulcerative colitis (UC) and 76 patients with Crohn's disease (CD) who were followed regularly at a single tertiary medical center in Korea between January 2003 and December 2012. Hemoglobin (Hb) thresholds used to define anemia were <13.0 g/dL in men and <12.0 g/dL in women according to the World Health Organization criteria. We chose the lowest Hb level in each year as a representative value because Hb levels changed at each examination and anemia was associated with disease deterioration. The relationship between clinical variables and lowest Hb level was assessed.

Results

The prevalence of anemia was 36.3% in patients with UC and 41.6% in patients with CD. Anemia in patients with CD was associated with hospital admission, 5-aminosalicylate (5-ASA) and infliximab treatment in men. Anemia in patients with UC was associated with hospital admission, oral steroid use, thiopurine and infliximab treatment in men.

Conclusions

The prevalence of anemia in Korean patients with IBD was comparable to that of patients in Western countries. Anemia was associated with male patients with CD who were admitted to the hospital and received medications including 5-ASA and infliximab, and men with UC who were admitted to the hospital and received medications including oral steroids, thiopurine and infliximab.

Perianal Abscess and Proctitis by Klebsiella pneumoniae: Woo Shin Jeong, Sung Youn Choi, Eun Haeng Jeong, Ki Bae Bang, Seung Sik Park, Dae Sung Lee, Dong Il Park, Yoon Suk Jung; Intest Res 2015;13(1):85-89. Published online January 29, 2015; DOI: https://doi.org/10.5217/ir.2015.13.1.85

Abstract PDF PubReader

Klebsiella pneumoniae (K. pneumoniae) can at times cause invasive infections, especially in patients with diabetes mellitus and a history of alcohol abuse. A 61-year-old man with diabetes mellitus and a history of alcohol abuse presented with abdominal and anal pain for two weeks. After admission, he underwent sigmoidoscopy, which revealed multiple ulcerations with yellowish exudate in the rectum and sigmoid colon. The patient was treated with ciprofloxacin and metronidazole. After one week, follow up sigmoidoscopy was performed owing to sustained fever and diarrhea. The lesions were aggravated and seemed webbed in appearance because of damage to the rectal mucosa. Abdominal computed tomography and rectal magnetic resonance imaging were performed, and showed a perianal and perirectal abscess. The patient underwent laparoscopic sigmoid colostomy and perirectal abscess incision and drainage. Extended-spectrum beta-lactamase-producing K. pneumoniae was identified in pus culture. The antibiotics were switched to ertapenem. He improved after surgery and was discharged. K. pneumoniae can cause rapid invasive infection in patients with diabetes and a history of alcohol abuse. We report the first rare case of proctitis and perianal abscess caused by invasive K. pneumoniae infection.

Abstract PDF PubReader ePub

Background/Aims

Several recent studies have reported that the early use of infliximab (IFX) improves the prognosis of Crohn's disease (CD). However, no data are available from Asian populations, as the forementioned studies have all been conducted in Western countries. The aim of the current study was to evaluate the impact of early use of IFX on the prognosis of Korean patients with CD.

Methods

Patients with a diagnosis of CD established between July 1987 and January 2012 were investigated in 12 university hospitals in Korea. Because insurance coverage for IFX treatment began in August 2005, patients were assigned to either of 2 groups based on diagnosis date. The first group included patients diagnosed from July 1987 to December 2005, and the second from January 2006 to January 2012. We compared the cumulative probabilities of operation and reoperation between the two groups using the Kaplan-Meier method and a log-rank test.

Results

Of the 721 patients investigated, 443 (61.4%) comprized the second group. Although the cumulative probabilities of immunosuppressant (P<0.001) and IFX use (P<0.001) after diagnosis were significantly higher in the second group, there were no significant differences in cumulative probabilities of operation (P=0.905) or reoperation (P=0.418) between two groups.

Conclusions

The early use of IFX did not reduce CD-related surgery requirements in Korean patients with CD. These study results suggest that the early use of IFX may have little impact on the clinical outcome of CD in Korean patients in the setting of a conventional step-up algorithm.

The Effect of Infliximab on Patients with Ulcerative Colitis in Korea: Hyun Il Seo, Dong Il Park, Tae Oh Kim, You Sun Kim, Suck-Ho Lee, Ji Won Kim, Jae Hak Kim, Jeong Eun Shin; Intest Res 2014;12(3):214-220. Published online July 25, 2014; DOI: https://doi.org/10.5217/ir.2014.12.3.214

Abstract PDF PubReader ePub

Background/Aims

Infliximab was introduced recently as a rescue therapy for ulcerative colitis (UC) patients refractory to conventional treatments such as therapy with 5-amiono salicylic acids (5-ASA), immune modulators, and corticosteroids. However, there is insufficient data about its efficacy and safety in Korea.

Methods

From 7 tertiary referral hospitals, 33 patients who were treated with infliximab for moderate to severe (Mayo score 6-12) UC refractory to conventional treatment were recruited to this study. Clinical remission was defined as a total Mayo score of 2 or lower and every subscore less than 2. Partial response was defined as a decrease of Mayo score at least 3 points from baseline.

Results

Twenty-three patients (69.7%) showed clinical remission and 29 patients (87.8%) showed partial response in the observation period. When the remission and non-remission groups were compared in univariate analysis, only a higher total Mayo score at base line (11.0±0.9 vs. 9.9±1.5; P=0.04) was related to remission. The remission maintenance rate decreased with time in the Kaplan-Meier analysis. Two patients experienced re-remission after the first remission followed by aggravation during infliximab treatment. Three patients stopped infliximab treatment owing to adverse events including rhabdomyolysis, pneumonia, and fever of unknown origin.

Conclusions

If there is no choice except surgery for UC patients refractory to conventional treatment, infliximab is an effective and relatively safe treatment option for these patients in Korea.

Abstract PDF

Background/Aims
A subset of patients may develop colorectal cancer after a colonoscopy that was negative for carcinoma. These missed or de novo developed lesions were termed as interval cancers. Many studies regarding interval cancer have been conducted in Western countries, whereas very limited data are available in Asian populations. Therefore, the purpose of this study was to investigate prevalence, clinicopathologic features, and predictors of interval colorectal cancers in the Korean population. Methods: Interval cancer was defined as a cancer that is diagnosed within 5 years of a negative colonoscopy result. Among the patients who were diagnosed colorectal cancers at Kangbuk Samsung Hospital from January 2007 to April 2012, clinicopathologic characteristics of interval cancers were compared with those of sporadic cancers. Results: Among the 785 patients, 482 responded to telephone calls. Of these, 30 (6.2%) developed interval cancers. Finally, 28 patients who had interval cancers were compared with 415 patients who had sporadic cancers. Interval cancer group was significantly younger and more frequent in the right side colon than sporadic cancer group. There was no differences in sex, tumor size, differentiation, and staging between two groups. In multivariate analysis, young age and right side colon cancer were independent factors associated with an interval cancer. Conclusions: A significant proportion of Korean patients developed interval colorectal cancer, especially at the young age and in the proximal colon. (Intest Res 2013;11:178-183)

Exposure to Diagnostic Radiation in Patients with Inflammatory Bowel Disease: A Single Center Study: Jae Wan Lim, Yoon Suk Jung, Jung Ho Park, Hong Joo Kim, Yong Kyun Cho, Chong Il Sohn, Woo Kyu Jeon, Byung Ik Kim, Dong Il Park; Intest Res 2013;11(2):107-112. Published online April 30, 2013; DOI: https://doi.org/10.5217/ir.2013.11.2.107

Abstract PDF: Background/Aims
Western studies recently reported that patients with inflammatory bowel disease (IBD) are exposed to diagnostic radiation at potentially harmful levels. There is little research, however, on exposure to diagnostic radiation in patients with IBD in Asian areas. The present study assessed cumulative radiation exposure dose in patients with IBD who were treated at a single-tertiary medical center in Korea and analyzed the factors that increased the exposure dose. Methods: Retrospective investigation was performed of the medical records of the patients who were followed up for 1 year or more in a period from January 2003 through November 2011 at Kangbuk Samsung Hospital. Results: Included in the study were 202 patients with IBD: 80 (39.6%) had Crohn's disease (CD) and 122 (60.4%) had ulcerative colitis (UC). The mean follow-up period was 4.2±2.5 years for CD and 4.3±1.4 years for UC. The mean culmulative effective dose (CED) for CD and UC were 39.7 and 11.0 mSv respectively (P<0.001). In CD, factors associated with increased CED were surgery, history of intravenous steroid treatment, and structuring or penetrating disease. Conclusions: A substantial proportion of IBD patients, especially CD patients, were exposed to significantly harmful amounts of diagnostic radiation, mainly due to computed tomography examination. Efforts should be made to reduced diagnostic medical radiation, especially in patients at risk for increased radiation exposure. (Intest Res 2013;11:107-112)

Abstract PDF

The incidence of colorectal carcinoid tumor is recently increasing as screening colonoscopy increased. Traditional carcinoid tumor had been known as low grade, malignant neuroendocrine cell orign tumor. In 2000, World Health Organization (WHO) suggested that carcinoid was called well-differentiated neuroendocrine tumor (NET). It recently updated in 2010 by WHO; according to the differentiation and malignant potential, NET classified with NET Grade 1, Grade 2, and neuroendocrine carcinoma. They suggested that NET had malignant potential in accordance with histopathologic characteristics. Therefore, WHO recommended the behavior code of NET as malignant. However, European Neuroendocrine Tumor Society (ENETS) proposed the behavior of NET to four grades based on the histopathologic features; benign, benign or low grade malignant, low grade malignant, and high grade malignant. Also, American Joint Committee on Cancer (AJCC) suggested that topography codes of NET were defined as malignant. Korean Standard Classification of Diseases (KCD) described the different codings of carcinoid (NET). The discrepancies of behavior code or coding system exist among WHO, ENETS, AJCC and KCD. Also, there were differences in the perception for topographic coding system between clinicians and pathologists. NETs of colorectum were reported with the variable clinical characteristics (especially, metastasis) and long term prognosis from many studies. Especially, risk of metastasis and long term prognosis of small sized NET (<1 cm) had some discrepancies and should be investigated prospectively. Therefore, the consensus about topographic codes of NET should be needed with multidisplinary approach among gastroenterologists, pathologists and surgeons. (Intest Res 2013;11:14-22)

The Effect of Transfection of RET9 and RET51 on Apoptosis in SW48 and RKO Colon Cancer Cells: Hyun Il Seo, Dong Il Park; Intest Res 2013;11(1):28-33. Published online January 31, 2013; DOI: https://doi.org/10.5217/ir.2013.11.1.28

Abstract PDF: Background/Aims
Dependent receptor can transmit both positive signal: proliferation, differentiation or migration; and negative signal: apoptosis. It depends on the presence of its ligand. This study was performed to determine the effects of transfection of dependent receptors in human colon cancer cell lines. Methods: Two dependent receptors (rearranged during transfection [RET]9 and RET51) were transfected into three human colon cancer cell lines: SW48, RKO and V400. Then, half of them were treated with glial cell line-derived neurotrophic factor (GDNF). Using ELISA and caspase assay, apoptosis was measured. Dose-response relation between GDNF and apoptosis was also analyzed. A pcDNA was used as an empty vector. Results: After transfection of RET51, apoptosis was increased in SW48 (70% with ELISA and 119% with caspase assay) and RKO (255% with ELISA and 106% with caspase assay) cell lines when compared with the pcDNA group. V400 cell line did not show increased apoptosis. Transfection of RET9 did not induce apoptosis in all of the three human colon cancer cell lines. Treatment with GDNF 12 hours after transfection of RET51 decreased apoptosis in SW48 (66% with ELISA and 60% with caspase assay) and RKO (39% with ELISA and 57% with caspase assay) when compared with the cell lines transfected with RET51 only. Apoptosis was down-regulated with increasing concentration of GDNF in RKO cell line. Conclusions: This study showed that the apoptosis of human colon cancer cell line can be controlled by manipulating the dependent receptors and its ligands. We present the possibility of therapeutic method using dependent receptor in colon cancer. (Intest Res 2013;11:28-33)

Frequency of Bone Marrow Toxicity by Using Pattern of Azathioprine in Inflammatory Bowel Disease Patients: Kyung Hee Hyun, Suck-Ho Lee, Jae Min Shin, Dong Il Park, Chang Kyun Lee, Jeong Eun Shin, Chang Soo Eun, Kyu Chan Huh, Young Hwangbo; Intest Res 2012;10(3):244-250. Published online July 31, 2012; DOI: https://doi.org/10.5217/ir.2012.10.3.244

Abstract PDF

Background/Aims
The most important adverse effect of azathioprine (AZA) is bone marrow toxicity (BMT). Many physicians have preferred a gradual dose increment (GDI) policy for the prevention of BMT. The aim of this study was to evaluate the efficacy of GDI for the prevention of AZA-induced BMT in inflammatory bowel disease (IBD) patients. Methods: The medical records of IBD patients who received AZA in 6 university hospitals were reviewed. The patients were divided into two groups: the GDI group (initial dose ＜1.5 mg/kg, gradually increased to a therapeutic dose) and the non-GDI group (initial therapeutic dose ≥2 mg/kg). Results: A total of 308 patients were enrolled (male to female ratio, 1:2.3; mean age, 34.91±14.19 years; ulcerative colitis, 43.5%; Crohn's disease, 55.2%; and intermediate colitis, 1.3%). The overall incidence of BMT was 16.2% (50/308). BMT developed most frequently between fourth to eighth week (26%, 13/50). The rate of BMT of the non-GDI group was significantly higher than that of the GDI group (27.5%, 11/40 vs. 14.6%, 39/268, P=0.038). A multivariate analysis showed that the only factor related to BMT was a non-GDI policy (P=0.036; odds ratio, 2.41; 95% confidence interval, 1.06-5.49). Conclusions: A GDI policy could be useful for reducing AZA-induced BMT in Korean IBD patients. (Intest Res 2012;10: 0-250)

Comparison of Bowel Preparation Quality between Clear-liquid Diet and No Diet Restriction: Woo Shin Jeong, Dong Il Park, Hyo Sun Seok, Seong Eun Kim, Suck-Ho Lee, Chang Kyun Lee, Chang Soo Eun, Dong Soo Han; Intest Res 2012;10(3):272-279. Published online July 31, 2012; DOI: https://doi.org/10.5217/ir.2012.10.3.272

Abstract PDF

Background/Aims
Adequate bowel preparation is essential for full visualization of colonic mucosa because detection of small polyps and neoplasms depends on the quality of bowel cleansing. The aims of this study were to compare the efficacy, tolerability of preparation and side effect between two groups: clear-liquid diet with polyethylene glycol (PEG) solution versus no diet restriction with PEG solution. Methods: This was a randomized single-blind prospective study. A total of 330 patients were randomly assigned to receive either 2 L PEG solution with a clear-liquid diet on the day before colonoscopy and another 2 L PEG solution on the day of the procedure (group 1) or 2 L PEG solution with a general diet on the day before colonoscopy and another 2 L PEG solution on the day of the procedure (group 2). Results: 162 patients were assigned to group 1 and 168 patients to group 2. The satisfactory quality of bowel preparation was not significantly different between the two groups (80.2%, 78.6%, P=0.707). Patient's compliance of the clear-liquid diet in group 1 was 50%. The satisfactory quality of bowel preparation was weakly better when the clear-liquid diet was given 2 or 3 times a day (group 1A) than 0 or once a day (group 1B) (74.1%, 86.4%, P=0.048). The tolerability of the PEG solution and side effects of preparation were not significantly different in the two groups (P=0.573, 0.686). Conclusions: Bowel preparation with no diet restriction and split-dose PEG solution was similar to preparation with a clear-liquid diet in efficacy, tolerability and side effect. Therefore, the use of the clear-liquid diet protocol should improve patient's compliance. (Intest Res 2012;10: 0-279)

Published online April 30, 2012; DOI: https://doi.org/10.5217/ir.2012.10.2.161

Abstract PDF

Background/Aims
Conflicting data have been reported about the seasonal variation in flare-up of inflammatory bowel disease (IBD). The aim of this study was to assess the occurrence of seasonal variations in flare-up of IBD in the Korean population. Methods: Patients with IBD, who underwent more than 1 year of follow-up and showed more than 1 episode of flare-up, were included. Flares of disease were refined as follows; receipt of a new prescription and increasing dose of corticosteroids, 5-ASA or immunosuppressant; hospitalized or operated due to development and worsening of symptoms; elevation of inflammatory marker due to worsening of Crohn's Disease Activity Index (CDAI) or Mayo score. In addition, for patients with more than two episodes of flare-up, they were investigated in a monthly and seasonal pattern. Results: Of 573 patients with IBD, 46 patients with Crohn's disease and 61 patients with ulcerative colitis were enrolled. There was no association between month of the year and flare of Crohn's disease (P=0.06) or ulcerative colitis (P=0.58). Further, no association between season of the year and flare of Crohn's disease (P=0.06) or ulcerative colitis (P=0.68). However, in Crohn's disease who experience 2 or more flare-ups, symptoms occurred more frequently during winter, especially December (P=0.029). Conclusions: In the Korean population, there was no association of seasonal and monthly variation in flares of Crohn's disease and ulcerative colitis. However, in Crohn's disease, individuals with 2 flar-up or more, symptoms occurred more frequently during December. (Intest Res 2012;10: 0-167)

Abstract PDF

Colorectal cancer is the second most common cancer in males and the fourth most common in females in Korea. Since the most of colorectal cancer occur through the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish Korean guideline for colorectal cancer screening and polyp detection. Korean Multi-Society Take Force developed the guidelines with evidence-based methods. Parts of the statements drawn by systematic reviews and meta-analyses. Herein we discussed the epidemiology of colorectal cancers and adenomas in Korea, optimal screening methods for colorectal cancer, and detection for adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

Korean Guidelines for Post-polypectomy Colonoscopic Surveillance: Dong-Hoon Yang, Sung Noh Hong, Young-Ho Kim, Sung Pil Hong, Sung Jae Shin, Seong-Eun Kim, Bo In Lee, Suck-Ho Lee, Dong Il Park, Hyun-Soo Kim, Suk-Kyun Yang, Hyo Jong Kim, Se Hyung Kim, Hyun Jung Kim, Multi-Society Task Force for Development of Guidelines for Colorectal Polyp Screening, Surveillance; Intest Res 2012;10(1):89-109. Published online February 29, 2012; DOI: https://doi.org/10.5217/ir.2012.10.1.89

Abstract PDF

Post-polypectomy surveillance has become a major indication for colonoscopy as a result of increased use of screening colonoscopy in Korea. However, because the medical resource is limited, and the first screening colonoscopy produces the greatest effect on reducing the incidence and mortality of colorectal cancer, there is a need to increase the efficiency of postpolypectomy surveillance. In the present report, a careful analytic approach was used to address all available evidences to delineate the predictors for advanced neoplasia at surveillance colonoscopy. Based on the results of review of the evidences, we elucidated the high risk findings of the index colonoscopy as follows: 1) 3 or more adenomas, 2) any adenoma larger than 10 mm, 3) any tubulovillous or villous adenoma, 4) any adenoma with high-grade dysplasia, and 5) any serrated polyps larger than 10 mm. In patients without any high-risk findings at the index colonoscopy, surveillance colonoscopy should be performed five years after index colonoscopy. In patients with one or more high risk findings, surveillance colonoscopy should be performed three years after polypectomy. However, the surveillance interval can be shortened considering the quality of the index colonoscopy, the completeness of polyp removal, the patient's general condition, and family and medical history. This practical guideline cannot totally take the place of clinical judgments made by practitioners and should be revised and supplemented in the future as new evidence becomes available.

Abstract PDF

There are indirect evidences to suggest that 80% of colorectal cancers (CRC) develop from adenomatous polyps and that, on average, it takes 10 years for a small polyp to transform into invasive CRC. In multiple cohort studies, colonoscopic polypectomy has been shown to significantly reduce the expected incidence of CRC by 76% to 90%. Colonoscopic polypectomy is performed frequently in primary outpatient clinics and secondary and tertiary medical centers in Korea. However, there are no evidence-based, procedural guidelines for the appropriate performance of this procedure, including the technical aspects. For the guideline presented here, PubMed, Medline, and Cochrane Library literature searches were performed. When little or no data from well-designed prospective trials were available, an emphasis was placed on the results from large series and reports from recognized experts. Thus, these guidelines for colonoscopic polypectomy are based on a critical review of the available data as well as expert consensus. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data become available. This guideline is intended to be an educational device to provide information that may assist endoscopists in providing care to patients. This guideline is not a rule and should not be construed as a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment. Clinical decisions for any particular case involve a complex analysis of the patient's condition and the available courses of action. (Intest Res 2012;10:110-124)

Comparison of Infliximab and Infliximab/Azathioprine for Maintenance Therapy in Korean Patients with Luminal Crohn's Disease: Hyun Sun Won, Dong Il Park, Chang Uk Chon, Hyo Sun Seok, Tae Wan Kim, Woon Je Heo, Chang Kyun Lee, Chang Soo Eun, Dong Soo Han, Suck-Ho Lee; Intest Res 2011;9(3):189-195. Published online December 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.3.189

Abstract PDF

Background/Aims
The benefits and risks of concomitant immunomodulators with infliximab maintenance therapy in patients with luminal Crohn's disease (CD) have not been adequately evaluated. We studied the influence of immunomodulator discontinuation in patients in remission with infliximab therapy through a restrospective case- control study. Methods: Medical records of 37 patients with luminal CD who received infliximab at four medical centers were retrospectively analyzed. We compared clinical and follow-up data of patients who were treated with infliximab alone with that of patients with combination therapy. Results: Among 37 patients, 31 (83.7%) were treated with infliximab plus azathioprine and six (16.2%) were treated with infliximab alone. Of the 31 patients receiving combination maintenance therapy, 26 (83.9%) were in complete remission after 12 months, as compared with five of six patients (83.3%) receiving infliximab alone. No significant difference was observed in remission rate between two groups (P=0.735). In total, 16.1% of patients in combination therapy and 16.7% in infliximab alone group reported side effects (P=1.000), but serious adverse events such as reactivation of tuberculosis were noted in only one patient in combination therapy group. Conclusions: Concomitant immunomodulators did not improve efficacy in patients with luminal CD who received scheduled infliximab maintenance. (Intest Res 2011;9:189-195)

Abstract PDF

Background/Aims
There are no evidence-based, procedural guidelines to appropriately perform a colon polypectomy. Thus, we investigated the treatment modality for colon polypectomy in Korea, using a web-based e-mail survey. Methods: A questionnaire of preferred treatment modality for colon polypectomy was sent via e-mail to members of the Korean Association for the Study of Intestinal Diseases and primary care physicians who performed colonoscopies as a screening or surveillance program nationwide. Among 425 colonoscopists who were sent the e-mail, 263 replied. We analysed data from 252 colonoscopists who had performed colon polypectomies. Results: The stopping time for antiplatelet and anticoagulation therapy before a colon polypectomy had a tendency to increase and the restarting time for these drugs was delayed as polyp size increased. Colonoscopists preferred cold biopsy removal for polyps <5 mm in size and a hot snare polypectomy after injecting normal saline and epinephrine mixture for polyps ≥5 mm in size. More than half of colonoscopists preferred observation rather than additional procedures for adenomas with incomplete resection. In contrast, most colonoscopists recommended additional procedures, such as endoscopic mucosal resection, endoscopic submucosal dissection or surgery for an advanced adenoma with incomplete resection. The most preferred prophylactic treatment for immediate postpolypectomy bleeding washemoclipping. Conclusions: Various treatment modalities were used for a colon polypectomy because there are few guidelines for performing a colon polypectomy based on a critical review of the available data. Further well-designed, prospective studies are needed to develop evidence-based guidelines for colon polypectomy. (Intest Res 2011;9:196- 205)

Usefulness of Polyp Detection Rate as a Quality Indicator in Colonoscopy: Su Hee Lee, Dong Il Park, Jun Mo Sung, Jae Hyun Jang, Seung Ho Ryu, Young Ho Kim, Suck-Ho Lee, Chang Kyun Lee, Chang Soo Eun, Dong Soo Han; Intest Res 2011;9(2):105-111. Published online August 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.2.105

Abstract PDF

Background/Aims
The adenoma detection rate (ADR) has been proposed as a quality indicator of colonoscopy; however, ADR cannot be measured easily with commonly used endoscopy reporting systems because substantial time and effort is required to acquire data from histologic assessments. The purpose of this study was to determine if polyp detection rate (PDR) could be used as a valid proxy for ADR. Methods: A total of 1,156 consecutive, asymptomatic, individuals of average risk between 50 and 75 years-of-age who underwent screening colonoscopies at four tertiary medical centers by 27 gastroenterologists were included in this study. Each individual endoscopist performed at least 10 colonoscopies during the study period. The ADR and PDR were calculated as the proportion of an endoscopist's cases with an adenoma or polyp divided by the total number of colonoscopies. Pearson's correlation coefficient and the intraclass correlation coefficient were used to determine the level of agreement between ADR and PDR. Results: The mean PDR and ADR for endoscopists was 47.4% (range, 21.7-75.0) and 36.5% (range, 13.0-66.7), respectively. There was a strong correlation between PDR and ADR (Pearson's correlation coefficient 0.94, P＜0.001) and there was also good agreement between performance quintiles defined by ADR and PDR (intraclass correlation coefficient 0.94, P＜0.001). Conclusions: PDR is a valid proxy for ADR and may be useful for quality assurance at centers where ADR cannot be easily measured. (Intest Res 2011;9:105-111)

Abstract PDF

Background/Aims
There is a paucity of information on postpolypectomy surveillance currently practiced in Korea. Thus, we investigated the present state of postpolypectomy surveillance in Korea using a web-based survey. Methods: A multiple choice questionnaire was used to determine the preferred surveillance modality, the colonoscopic surveillance interval used in 11 case scenarios, and clinical factors influencing surveillance intervals. The form was sent via e-mail to members of the Korean Association for the Study of Intestinal Diseases and primary care physicians involved in a colonoscopy surveillance program. Of 425 colonoscopists contacted, 263 replied (response rate, 62%). Of the respondents, 94% were internists and 54% practiced in tertiary referral hospitals. Results: All respondents chose colonoscopy as a preferred surveillance modality following polyp removal. Colonoscopy at 3 years was the most frequent answer after removal of 1 or 2 tubular adenoma(s) ＜1 cm in size, while 1 year was the most frequent answer after removal of an advanced adenoma or ≥3 adenomas, and 6 months was the most frequent choice after removal of adenoma with high-grade dysplasia or a sessile polyp ≥2 cm. The agreement rate for the time of first surveillance between preferred guideline recommendations and respondent answers was in the low range at 14-43%. Conclusions: A significant disagreement exists between current postpolypectomy surveillance practices of Korean colonoscopists and preferred guideline recommendations. This discrepancy may be due to the fact that the guidelines do not reflect recent studies and the specific medical environment in Korea. Thus, there is a need to develop new evidence-based Korean guidelines for postpolypectomy surveillance. (Intest Res 2011;9:118-128)

Published online April 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.1.1

Abstract PDF

The Korean Standard Classification of Diseases (KCD), which reflects the International Classification of Diseases (ICD), is a fundamental coding system for the diagnosis of colorectal epithelial tumors. The KCD coding of colorectal lesions is entirely up to the clinician and is based on pathologic reports. However, coding discrepancies have arisen among physicians using the KCD and pathologists using the ICD for Oncology-3 (ICD-O-3). The Korean Society of Pathologists recently proposed a standardized pathology-reporting format and guidelines for the coding of colorectal cancer to decrease these discrepancies among pathologists. However, ICD and ICD-O are simple classification codes based on pathologic reports, and are neither intended nor suitable for indexing of distinct clinical entities. For appropriate diagnostic coding using the KCD, a corrected coding principle based upon pathologic reports is required, and unified coding between KCD and ICD-O is necessary. A standardized pathologic report format and communication with understanding between physicians and pathologists should be established. Additionally, the private medical insurance system for colorectal cancer should be revised to reduce conflicts among patients, clinicians, and insurance companies over the medical coding system.

Comparison of Bowel Preparation Depending on Completion Time of Polyethylene Glycol Ingestion and Start Time of Colonoscopy: Jang Hyuk Yoon, Dong Il Park, Jeong Eun Shin, Seong Eun Kim, Sung Ae Jung, Suck Ho Lee, Dong Kyung Chang, Chang Soo Eun, Dong Soo Han, Hyun Soo Kim, Seun Ja Park, Il Hyun Baek, Bora Keum, Yoon Tae Jeen; Intest Res 2010;8(1):24-29. Published online June 30, 2010; DOI: https://doi.org/10.5217/ir.2010.8.1.24

Abstract PDF

Background/Aims
Polyethylene glycol (PEG) solution is the most widely used bowel preparation agent for colonoscopy because of its safety and efficacy in colon cleansing. It has been hypothesized that the timing of colon preparation may influence the quality of colon cleansing, and therefore affect the diagnostic yield of colonoscopy. The aim of this study was to determine the optimal interval of time between complete ingestion of PEG and performing colonoscopy. Methods: We prospectively enrolled 1,355 patients who had undergone a PEG-based bowel preparation on the day of colonoscopy in 11 tertiary hospitals in Korea between March 2008 and February 2009. All colonoscopies were performed in the afternoon. The start time of PEG ingestion, completion time of PEG ingestion, dose of PEG ingested, start time of colonoscopy, and the quality of bowel cleansing were recorded. Results: There was no difference of cleansing quality of bowel preparation between three groups of less than 7 hours of elapsed time (2≤ and <3 hours, 3≤ and <5 hours, 5≤ and <7 hours). However, group of more than 7 hours of elapsed time presented poor cleansing quality than others (P<0.01). Conclusions: If >7 hours elapses after ingestion of PEG, the quality of bowel preparation is poor. Therefore, depending on the time colonoscopy is scheduled, the start time of PEG ingestion may need to be adjusted. (Intest Res 2010;8:24-29)

Clinical Significance of Screening Colonoscopy in Elderly: A KASID Multi-center Study: Sung Geun Park, Dong Il Park, Young-Ho Kim, Hyun Soo Kim, Won Ho Kim, Tae Il Kim, Hyo Jong Kim, Suk-Kyun Yang, Jeong-Sik Byeon, Moon Sung Lee, Il Kwon Jung, Moon Kwan Chung, Sung-Ae Jung, Yoon Tae Jeen, Jai Hyun Choi, Hwang Choi, Dong Soo Han, Jae Suk Song; Intest Res 2008;6(1):25-30. Published online June 30, 2008

Abstract PDF: Background/Aims
Currently, screening colonscopy is widely performed in the medical field. The initial time of screening is recommended at an age of 50 years, but the age to cease screening is unknown. Accordingly, we have investigated the diagnostic yield of colonoscopy according to indications in the elderly, and we evaluated if screening colonoscopy is useful in the elderly. Methods: We recruited asymptomatic individuals undergoing screening colonoscopy according to age (2830 subjects aged 50-74 years and 111 subjects ≥75 years-old), The colonoscopy findings of the study subjects were compared. In addition, colonoscopy findings of asymptomatic subjects more than 75 years-old were compared with the findings of symptomatic subjects with the same age. Results: The yield for overall neoplasia and advanced adenoma was higher in the group of subjects ≥75 years-old than in the 50-74 years age group (overall adenoma: 49.54% versus 24.98%, p＜0.001; advanced adenoma: 16.2% versus 8.23%, p=0.003). The overall frequency of neoplasms was higher in asymptomatic subjects ≥75 years-old than in symptomatic subjects ≥75 years-old (49.54% versus 28.19%, p＜0.001). Conclusions: The prevalence of advanced adenoma increased with age. Screening colonoscopy was still significantly effective in elderly subjects ≥75 years-old. The lack of a decline in the frequency of adenoma, including advanced adenoma, justifies continuing screening colonoscopy in the elderly. (Intest Res 2008;6:25-30)

A Case of Pulmonary Tuberculosis Misdiagnosed as Lung Metastases after Curative Resection of Early Colon Cancer: Chang Joon Kim, Dong Il Park, Sung Keun Park, Jung Ho Park, Chong Il Sohn, Woo Kyu Jeon, Young-Ho Kim, Sun-Young Lee; Intest Res 2007;5(2):196-199. Published online December 30, 2007

Abstract PDF: Early colon cancer can be cured by endoscopic mucosal resection (EMR). However, the possibility of complete resection depends on the depth of cancer invasion. Ten percent of cancers invading the submucosal layer are associated with local lymph node metastasis. Therefore, colon cancers confirmed to invade the submucosal layer after EMR require surgical resection. We treated a woman with adenocarcinoma at the hepatic flexure with submucosal invasion diagnosed after piecemeal EMR. Subsequent right hemicolectomy with lymph node dissection revealed no residual cancer. However, after 21 months, multiple pulmonary nodules were incorrectly diagnosed as pulmonary metastases, based on the radiological findings. The final diagnosis of pulmonary tuberculosis was made after lung metastasectomy. (Intest Res 2007;5:196-199)

Clinicopathological Characteristics and Malignant Potential of Colonic Flat Adenomas Compared to That of Polypoid Adenomas: Myeong Gwan Jee, Hyun Soo Kim, Won Ho Kim, Tae Il Kim, Dong Il Park, Young-Ho Kim, Hyo Jong Kim, Jeong-Sik Byeon, Suk-Kyun Yang, Moon Sung Lee, Il Kwon Jung, Sung-Ae Jung, Yoon Tae Jeen, Jai Hyun Choi, Hwang Choi, Kyu Yong Choi, Dong Soo Han; Intest Res 2005;3(2):127-132. Published online December 30, 2005

Abstract PDF: Background/Aims
Colorectal flat adenomas have been a topic of debate in the view of malignant potential. The aims of this study are to investigate the clinicopathological features of flat adenomas compared to that of polypoid adenomas and to identify the determinants for malignant transformation in colorectal flat and polypoid adenomas. Methods: This was a prospective, cross sectional study of 3,360 patients who diagnosed as adenomas via total colonoscopy and polypectomy at 13 tertiary medical centers between July 2003 and July 2004. Potential risk factors for malignant transformation were analyzed. Results: Out of 3,360 adenomas, 207 (6.2%) were flat adenomas and 3,153 (93.8%) were polypoid adenomas. The patients with flat adenoma were older (59.6 vs. 57.1, p＜0.01) and more frequently located in the right colon than polypoid adenomas (49.3% vs. 32.0%, p<0.01). The incidence of high grade dysplasia or cancer in flat adenomas was similar to that of polypoid adenomas (5.4% vs. 4.6%, p=0.36). Multivariate analysis revealed that the size ≥11 mm (OR 6.8; 95% CI 4.8-9.7) and location of adenoma in the left colon (OR 1.6; 95% CI 1.07-2.38) were significant determinants for malignant potential of colonic adenoma. Conclusions: Clinicopathological determinants for malignant potential in colorectal adenomas were not gross morphology but size and location of adenoma. (Intestinal Research 2005;3:127-132)
