AbstractAbstract PDFPubReaderePub
The treatment of inflammatory bowel disease (IBD) has been revolutionized for the last 10 years by the increasing use of immunomodulators and biologics. With immunosuppression of this kind, opportunistic infection is an important safety concern for patients with IBD. In particular, viral hepatitis is determined by the interaction between the virus and the host’s immunity, and the risk of reactivation increases if immunity is compromised by immunosuppression therapy. Parts of Asia, including Korea, still show intermediate endemicity for the hepatitis A virus and hepatitis B virus compared with the United States and Western Europe. Thus, members of IBD research group of the Korean Association for the Study of Intestinal Diseases have produced a guideline on the prevention and management of viral hepatitis in IBD.

AbstractAbstract PDFPubReaderePub

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.

Endoscopy
Quality is the key for emerging issues of population-based colonoscopy screening
Jin Young Yoon, Jae Myung Cha, Yoon Tae Jeen
Intest Res 2018;16(1):48-54.   Published online January 18, 2018

AbstractAbstract PDFPubReaderePub

Colonoscopy is currently regarded as the gold standard and preferred method of screening for colorectal cancer (CRC). However, the benefit of colonoscopy screening may be blunted by low participation rates in population-based screening programs. Harmful effects of population-based colonoscopy screening may include complications induced by colonoscopy itself and by sedation, psychosocial distress, potential over-diagnosis, and socioeconomic burden. In addition, harmful effects of colonoscopy may increase with age and comorbidities. As the risk of adverse events in population-based colonoscopy screening may offset the benefit, the adverse events should be managed and monitored. To adopt population-based colonoscopy screening, consensus on the risks and benefits should be developed, focusing on potential harm, patient preference, socioeconomic considerations, and quality improvement of colonoscopy, as well as efficacy for CRC prevention. As suboptimal colonoscopy quality is a major pitfall of population-based screening, adequate training and regulation of screening colonoscopists should be the first step in minimizing variations in quality. Gastroenterologists should promote quality improvement, auditing, and training for colonoscopy in a population-based screening program.

AbstractAbstract PDF
Ulcerative colitis is associated with various extra-intestinal manifestations, including rheumatic, dermatologic, ophthalmologic, biliary, and hematologic manifestations. Cutaneous findings are common extra-intestinal manifestations of ulcerative colitis, occurring in 10-20% of patients. Cutaneous manifestations include erythema nodosum, pyoderma gangrenosum, aphthous stomatitis, and acute febrile neutrophilic dermatosis. Treatments for these cutaneous manifestations include corticosteroids, cyclosporine, tacrolimus, mycophenolate mofetil, azathioprine, and infliximab. A 48-year-old male presented with an acute exacerbation of ulcerative colitis associated with multiple skin lesions on his face, thumbs, thighs, and feet. The final impression was neutrophilic folliculitis, which is an early form of pyoderma gangrenosum. The patient's skin lesions and colitis both improved with corticosteroids. There are rare published case reports of ulcerative colitis exacerbations associated with pyoderma gangrenosum that initiated as neutrophilic folliculitis of the face. This case report includes a review of the literature. (Intest Res 2011;9:225-229)

AbstractAbstract PDF
Cronkhite-Canada syndrome (CCS) is a rare, non-familial hamartomatous polyposis syndrome characterized by multiple polyps in the entire gastrointestinal tract, nail dystrophy, skin pigmentation, and systemic alopecia. The clinical symptoms of this syndrome include diarrhea, abdominal pain, and alopecia often accompanied by taste disturbances, hypoalbuminemia, recurrent infections, nutritional absorption disturbances, heart failure, and gastrointestinal bleeding. We report a patient with CCS who was admitted complaining of hematochezia, melena, and a 1 month history of diarrhea, nail changes, taste disturbances, and alopecia. Upper endoscopy, colonoscopy, and capsule endoscopy were performed and showed numerous polyps in the stomach, small intestine, and large intestine. Histological sections of these polyps showed edematous stroma and cystically dilated foveolar epithelium, which was consistent with CCS. We diagnosed CCS based on the clinical symptoms and the histological findings of the polyps found via endoscopy. We report on this case and review this syndrome. (Intest Res 2011;9:238-242)

AbstractAbstract 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)

AbstractAbstract PDF
Background/Aims
C-reactive protein (CRP) is a general marker of inflammation and increased CRP level is reported in several cancers. It has been reported that CRP is an independent factor predicting survival in colorectal cancer patients, although this claim is still under debate. The aim of this study was to investigate the association between CRP and the characteristics of colorectal cancer patients. Methods: One hundred eighty-four patients diagnosed with colorectal cancer between January 2007 and January 2009 were included. The patients with active infectious diseases, other tumors, cardiovascular disease, or inflammatory bowel disease were excluded. The CRP levels of colorectal cancer patients were compared with the control group comprised of 175 healthy adults with a normal colonoscopy. Results: The median CRP in the colorectal cancer patients (3.36 mg/L) was higher than the control group (0.48 mg/L). There was a significant correlation between CRP and the stage of colorectal cancer (p<0.001). CRP was increased significantly in Dukes' stage D. CRP had a significant correlations with the CEA and CA 19-9 levels, the ESR, and the white blood cell count, and an inverse correlation with albumin. The CRP level in colon cancer patients was higher than rectal cancer patients (p=0.032). There were no significant difference in the CRP according to metastatic sites, such as the liver and peritoneum. Conclusions: Serum CRP levels were higher in patients with colorectal cancer and high CRP level is a predictor of advanced disease. (Intest Res 2009;7:93-99)

AbstractAbstract 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)

AbstractAbstract PDF
Background/Aims
The effect of tegaserod has been found to differ for Caucasian and black patients. The aims of this study were to demonstrate the efficacy of tegaserod on bowel habits and to investigate the factors affecting the efficacy of tegaserod in Korean patients suffering from chronic constipation (CC). Methods: This was an open-label, multi-center, observational study. Analysis of covariance with repeated measures was used to determine the overall effect of treatment and was used to determine the changes in the number of complete spontaneous bowel movements (CSBM) from baseline during the 8-week treatment period. Demographic and baseline characteristics were compared between responders (3 or more CSBM at 8-weeks) and non-responders by the use of multivariate analysis. Results: A total of 1,798 patients were included in the study. Tegaserod treatment resulted in a significant increase in the mean number of CSBM per week over weeks 2-8 from baseline levels (from 1.0 to 3.1 CSBM per week, p<0.0001). Tegaserod treatment was more effective for female patients, younger patients (age less than 65 years), patients with a high Bristol score at baseline, and patients with a short duration of constipation symptoms. Conclusions: Treatment with tegaserod improved bowel movements and more effective in female patients, patients under the age of 65 years, patients with a high Bristol score at baseline, and patients with a short duration of constipation symptoms.

Problems in the Diagnosis of Inflammatory Bowel Disease in Korea
Yoon Tae Jeen, Yong Dae Kwon
Intest Res 2006;4(2):75-78.   Published online December 30, 2006
AbstractAbstract PDF
Inflammatory bowel disease (IBD) is defined as chronic inflammatory intestinal disorder of unknown origin. Not only Crohn's disease (CD) and ulcerative colitis (UC) are widely known as such IBD, but Behcet's colitis and intestinal tuberculosis also belong to IBD. Particularly because intestinal tuberculosis is common disorder in Korea; Crohn's disease (CD) is on the increase, the differentiation of intestinal tuberculosis from CD is very important. Even though theses diseases have similar clinical feature, their eventual course is quite different. However diagnosis of IBD is intricate because of no pathognomonic feature. Recently introduction of CARD15/NOD2 gene polymorphism which causes increasing of incidence of CD intensifies genetic diagnostic tool research, and new diagnostic approach as systematic analysis of endoscopic findings is suggested. Therefore more advanced and more convenient method to diagnose IBD will be developed in near future. (Intestinal Research 2006;4:75-78)

AbstractAbstract PDF
Background/Aims
Colon cancer has a multistep process of molecular changes on the way of carcinogenesis. The detection of gene mutations associated with those molecular changes is expected to be able to predict or diagnose colon cancer. Calreticulin is one of the protein which has being investigated as a biomarker of colorectal cancer. The Aims of this study was to demonstrate the expression of calreticulin in normal colon mucosa, colonic tubular adenoma and colorectal cancer of each patient, and analyze the differences among them. Methods: 8 patients who have colorectal adenocarcinoma and more than 10 mm sized tubular adenoma synchronously were enrolled. Colorectal adenocarcinoma, tubular adenoma and normal colon tissue were taken from each patient. After proteins isolation and separation, western blot assay were performed to demonstrate calreticulin. The results were analyzed by Wilcoxon Signed Rank Test. Results: Calreticulin was more expressed in colorectal adenocarcinoma and tubular adenoma significantly compared with normal mucosa. Also, calreticulin was more expressed in adenocarcinoma than in adenoma but there were no significant diffences. Conclusions: These results suggest that calreticulin may be available for an early diagnostic biomarker for colorectal cancer or advanced colon adenoma. (Intestinal Research 2006;4:7-11)

AbstractAbstract PDF
Backgroud/Aims: Proximal lesion without distal finding is weak point in colon cancer screening. Clinical significance of distal finding for advanced proximal neoplasia (APN) is uncertain. Aims of this study were to assess distal finding for prediction of APN. Methods: Asymptomatic 826 adults (age≥50) were collected in KASID prospective study, who underwent colonoscopy and polypectomy. Polyps located distal to splenic flexure were defined as distal polyps. Age, gender, size, appearance, histology of distal polyps were analyzed as risk factor of APN (adenoma≥10 mm or villous histology or high grade dysplasia or invasive cancer). Sensitivity and positive predictive value of distal polyp on APN were assessed. Results: APN were found in 98 patients and 45 (45.9%) patients of them were not associated with any distal findings. Risk factors of APN were male, size of distal polyp and advanced distal polyp. Sensitivity of distal polyp size≥10 mm on APN was 38.8% and advanced distal polyp also 38.8%. Positive predictive value of distal polyp size≥10 mm and advanced distal polyp were 13.3%, 14.4% respectively. Conclusions: Although distal colon findings were helpful to predict APN in asymptomatic 50 years of age or order patients screening, more careful examination is required considering APN without distal polyps.

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)

Background/Aims
The current practice of colonoscopic polypectomy reduce the risk of colorectal cancer. However, clinicopathologic charateristics of colorectal adenoma in population under 50 years old are uncertain. This study was performed to investigate clinicopathologic characteristics of colorectal adenoma and to determine colonoscopic indication of advanced adenoma in this population. Methods: A large scale, multicenter, prospective study was conducted from July 2003 through June 2004. Of the total 19,288 patients performed colonoscopy at 11 tertiary medical centers, we analysed 3,366 patients who undergone polypectomy and divided two groups by age of 50. Results: Among colonoscopic polypectomy, 10.7 percent (831/7,789) was younger patients and 22.0 percent (2.535/11,499) was older patients (p<0.001), and the detection rate of advanced adenoma was significantly lower in younger patients than older patients (17.7% vs. 21.1%, p<0.0050). In younger patients, the indications of colonoscopy were asymptomatic screening (32.7%), bowel habit change (24.0%), abdominal pain (16.8%), hematochezia (9.2%) and so on. The risk factors for advanced adenoma as colonoscopic indications in younger patients were hematochezia (OR 1.9, 95% CI 1.1-3.3) and referred patients from primary clinic (OR 2.0, 95% CI 1.3-3.0). Conclusions: This study documents lower prevalence of adenoma requiring polypectomy in younger patients compared with older patients and the low detection rate of advanced adenoma. Also, in this younger population, the colonoscopic polypectomy should be the first consideration in polyps with hamatochezia patients or referred patients from primary clinic.
