Abstract PDF Supplementary Material PubReader ePub: Background/Aims
We investigated the clinical practice patterns of post-polypectomy colonoscopic surveillance among Korean endoscopists.
Methods
In a web-based survey conducted between September and November 2021, participants were asked about their preferred surveillance intervals and the patient age at which surveillance was discontinued. Adherence to the recent guidelines of the U.S. Multi-Society Task Force on Colorectal Cancer (USMSTF) was also analyzed.
Results
In total, 196 endoscopists completed the survey. The most preferred first surveillance intervals were: a 5-year interval after the removal of 1–2 tubular adenomas < 10 mm; a 3-year interval after the removal of 3–10 tubular adenomas < 10 mm, adenomas ≥ 10 mm, tubulovillous or villous adenomas, ≤ 20 hyperplastic polyps < 10 mm, 1–4 sessile serrated lesions (SSLs) < 10 mm, hyperplastic polyps or SSLs ≥ 10 mm, and traditional serrated adenomas; and a 1-year interval after the removal of adenomas with highgrade dysplasia, >10 adenomas, 5–10 SSLs, and SSLs with dysplasia. In piecemeal resections of large polyps ( > 20 mm), surveillance colonoscopy was mostly preferred after 1 year for adenomas and 6 months for SSLs. The mean USMSTF guideline adherence rate was 30.7%. The largest proportion of respondents (40.8%–55.1%) discontinued the surveillance at the patient age of 80–84 years.
Conclusions
A significant discrepancy was observed between the preferred post-polypectomy surveillance intervals and recent international guidelines. Individualized measures are required to increase adherence to the guidelines.

Inflammatory Bowel Diseases

The role of platelet to lymphocyte ratio and neutrophil to lymphocyte ratio in ulcerative colitis: Yujin Jeong, Seong Ran Jeon, Hyun Gun Kim, Jung Rock Moon, Tae Hee Lee, Jae Young Jang, Jun-Hyung Cho, Jun Seok Park, Heesu Park, Ki-hun Lee, Jin-Oh Kim, Joon Seong Lee, Bong Min Ko, Suyeon Park; Intest Res 2021;19(1):62-70. Published online May 8, 2020; DOI: https://doi.org/10.5217/ir.2019.09156

Abstract PDF PubReader ePub

Background/Aims
Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) can serve as biomarkers for diagnosing and assessing disease activity in ulcerative colitis (UC). We investigated their clinical significance in UC.
Methods
We analyzed 48 patients with UC who underwent measurement of fecal calprotectin (FC) and endoscopy and 96 age- and sex-matched healthy controls. NLR and PLR were compared between the patients and healthy controls. The endoscopic activity was divided into 2 groups: group 1 (mild to moderate inflammation) and group 2 (severe inflammation) according to the Mayo endoscopic subscore in UC.
Results
To diagnose UC, the optimal cutoff of NLR and PLR was 2.26 (sensitivity 54.2%; specificity 90.6%; positive likelihood ratio 5.778, 95% confidence interval [CI] 2.944–11.339; area under the curve [AUC] 0.774, 95% CI, 0.690–0.859) and 179.8 (sensitivity 35.4%; specificity 90.6%; positive likelihood ratio 3.778, 95% CI 1.821–7.838; AUC 0.654, 95% CI 0.556–0.753), respectively. The optimal cutoff to differentiate group 1 and group 2 was 3.44, 175.9, and 453 µg/g for NLR, PLR, and FC, respectively (sensitivity, 63.6% vs. 90.9% vs. 81.8%; specificity, 81.1% vs. 78.4% vs. 73.0%; positive likelihood ratio, 3.364 vs. 4.205 vs. 3.027; AUC, 0.714 vs. 0.897 vs. 0.813). PLR had the highest AUC and positive likelihood ratio.
Conclusions
NLR and PLR help differentiate patients with UC from healthy controls. NLR, PLR, and FC indicate endoscopic activity and may reflect intestinal mucosal conditions.

Colorectal neoplasia

Clinical outcomes of positive resection margin after endoscopic mucosal resection of early colon cancers: Junseok Park, Hyun Gun Kim, Shin Ok Jeong, Hoon gil Jo, Hyo Yeop Song, Jeeyeon Kim, Seri Ryu, Youngyun Cho, Hyun Jin Youn, Seong Ran Jeon, Jin-Oh Kim, Bong Min Ko, Yoon Mi Jeen, So-Young Jin; Intest Res 2019;17(4):516-526. Published online May 31, 2019; DOI: https://doi.org/10.5217/ir.2018.00169

Abstract PDF PubReader ePub

Background/Aims
When determining the subsequent management after endoscopic resection of the early colon cancer (ECC), various factors including the margin status should be considered. This study assessed the subsequent management and outcomes of ECCs according to margin status.
Methods
We examined the data of 223 ECCs treated by endoscopic mucosal resection (EMR) from 215 patients during 2004 to 2014, and all patients were followed-up at least for 2 years.
Results
According to histological analyses, the margin statuses of all lesions after EMR were as follows: 138 cases (61.9%) were negative, 65 cases (29.1%) were positive for dysplastic cells on the resection margins, and 20 cases (8.9%) were uncertain. The decision regarding subsequent management was affected not only by pathologic outcomes but also by the endoscopist’s opinion on whether complete resection was obtained. Surgery was preferred if the lesion extended to the submucosa (odds ratio [OR], 25.46; 95% confidence interval [CI], 7.09–91.42), the endoscopic resection was presumed incomplete (OR, 15.55; 95% CI, 4.28–56.56), or the lymph system was invaded (OR, 13.69; 95% CI, 1.76–106.57). Fourteen patients (6.2%) had residual or recurrent malignancies at the site of the previous ECC resection and were significantly associated with presumed incomplete endoscopic resection (OR, 4.59; 95% CI, 1.21–17.39) and submucosal invasion (OR, 5.14; 95% CI, 1.18–22.34).
Conclusions
Subsequent surgery was associated with submucosa invasion, lymphatic invasion, and cancer-positive margins. Presumed completeness of the resection may be helpful for guiding the subsequent management of patients who undergo endoscopic resection of ECC.

Clinical comparison of low-volume agents (oral sulfate solution and sodium picosulfate with magnesium citrate) for bowel preparation: the EASE study: Jeeyeon Kim, Hyun Gun Kim, Kyeong Ok Kim, Hyung Wook Kim, Jongha Park, Jeong-Sik Byeon, Sung-Wook Hwang, Hyun Deok Shin, Jeong Eun Shin, Hyo-Joon Yang, Hyun Seok Lee, Yunho Jung, Young-Seok Cho, Young Eun Joo, Dae-Seong Myung, Kyu Chan Huh, Eu Mi Ahn; Intest Res 2019;17(3):413-418. Published online April 8, 2019; DOI: https://doi.org/10.5217/ir.2018.00156

Abstract PDF PubReader ePub

Background/Aims
This study compared the efficacy, compliance, and safety of bowel preparation between sodium picosulfate with magnesium citrate (SPMC) and oral sulfate solution (OSS).
Methods
A prospective randomized multicenter study was performed. Split preparation methods were performed in both groups; the SPMC group, 2 sachets on the day before, and 1 sachet on the day of the procedure, the OSS group, half of the OSS with 1 L of water on both the day before and the day of the procedure. The adenoma detection rate (ADR), adequacy of bowel preparation using the Boston Bowel Preparation Scale (BBPS) score, patient satisfaction on a visual analog scale (VAS), and safety were compared between the 2 groups.
Results
This study analyzed 229 patients (121 in the SPMC group and 108 in the OSS group). ADR showed no differences between 2 groups (51.7% vs. 41.7%, P> 0.05). The mean total BBPS score (7.95 vs. 8.11, P> 0.05) and adequate bowel preparation rate (94.9% vs. 96.3%, P> 0.05) were similar between the 2 groups. The mean VAS score for taste (7.62 vs. 6.87, P=0.006) was significantly higher in the SPMC group than in the OSS group. There were no significant differences in any other safety variables between the 2 groups except nausea symptom (36.1% vs. 20.3%, P=0.008).
Conclusions
Bowel preparation for colonoscopy using low volume OSS and SPMC yielded similar ADRs and levels of efficacy. SPMC had higher levels of satisfaction for taste and feeling than did OSS.

Practice patterns and clinical significance of use of capsule endoscopy in suspected and established Crohn's disease: Yonghyun Kim, Seong Ran Jeon, Sang Myung Choi, Hyun Gun Kim, Tae Hee Lee, Jun-Hyung Cho, Yunho Jung, Wan Jung Kim, Bong Min Ko, Jin-Oh Kim, Joon Sung Lee, Moon Sung Lee; Intest Res 2017;15(4):467-474. Published online October 23, 2017; DOI: https://doi.org/10.5217/ir.2017.15.4.467

Abstract PDF PubReader ePub

Background/Aims

Although the role of capsule endoscopy (CE) in Crohn's disease (CD) has expanded, CE is not used routinely for diagnosing and evaluating CD in Korea. We aimed to investigate current patterns of practice and evaluate the clinical significance of the use of CE in CD in Korean patients.

Methods

Among 651 CE procedures performed for various indications, we retrospectively analyzed the medical records of patients who underwent CE in 57 cases of suspected CD (sCD) and 14 cases of established CD (eCD).

Results

In the sCD group, CE was most commonly used for the initial diagnosis of CD (54.4%). Capsule retention was found in only 1 patient in the eCD group (1/71, 1.4%). In the sCD group, 28.1% of patients were diagnosed with CD on the basis of CE findings; other diseases diagnosed included tuberculous enteritis (7.0%), non-steroidal anti-inflammatory drug-induced enteropathy (5.3%), and other enteritis (17.5%). Only 11.5% of patients with eCD (14/122) underwent CE. The indication for CE in the 14 patients with eCD was to assess disease extent and activity. The overall diagnostic yield of CE was 59.7%. Therapeutic strategies were changed in 70.2% of patients in the sCD group and 50% of those in the eCD group based on CE findings.

Conclusions

In clinical practice, CE was most commonly indicated for the initial diagnosis of CD and was not generally performed in patients with eCD. CE appears to be an effective diagnostic modality for evaluating sCD and is useful for determining therapeutic strategies for patients with sCD and those with eCD.

Abstract PDF Supplementary Material PubReader ePub

Background/Aims

Inflammatory bowel disease (IBD) is a chronic disabling gastrointestinal disorder that diminishes the quality of life of the affected individuals. Limited data are available regarding the impact of IBD on the daily life of Koreans.

Methods

Self-administered, computer-aided, internet-based questionnaires were distributed to members of a Korean patient organization for IBD from March to April 2013, by the Korean Association for the Study of Intestinal Diseases.

Results

A total of 599 patients with IBD (387 with Crohn's disease [CD] and 212 with ulcerative colitis [UC]) were enrolled. The majority of patients (81%) expressed feelings of fatigue, weakness, and being worn out in their daily lives during times of flare; this percentage was reduced to 61% during remission. Respondents were absent from work or school for an average period of 18 days because of illness, within the first 6 months; the majority of respondents (64%) felt stressed about their absence. Forty-six percent of the respondents reported having received unfair comments at work, or having suffered discrimination. Forty-seven percent of the respondents felt that IBD had negatively affected their income and earnings. Compared with patients with UC, those with CD reported a more frequent negative impact of IBD on work, or more economic burden. More than half of the respondents (61%) reported that IBD had prevented them from making or keeping friends.

Conclusions

IBD significantly impacts daily life, including work, education, and social relationships. Treatment that addresses the full spectrum of life of a patient would be more effective.

Abstract PDF PubReader ePub

Background/Aims

Pneumoperitoneum is recognized as a benign and self-limiting finding after the insertion of a percutaneous endoscopic gastrostomy (PEG) tube, while complicated pneumoperitoneum is rarely reported. The aim of this study was to reappraise pneumoperitoneum following PEG.

Methods

We retrospectively reviewed 193 patients who underwent PEG from May 2008 to May 2014. All patients had a follow-up upright chest or simple abdominal radiograph after PEG. Pneumoperitoneum was quantified by measuring the height of the air column under the diaphragm and graded as small (<2 cm), moderate (2-4 cm), or large (>4 cm). Clinically significant signs were defined as fever, abdominal tenderness or leukocytosis occurring after PEG insertion.

Results

Of the 193 study patients, 9 (4.6%) had a pneumoperitoneum visualized by radiographic imaging, graded as small in 5 patients, moderate in 2 patients and large in 2 patients. Clinically significant signs were observed in 5 (55.5%) patients with fever reported in 4 patients, abdominal tenderness in 4 patients and leukocytosis in 4 patients. The time to resolution of free air was 2-18 days. Two patients (22.2%) with moderate or large pneumoperitoneum after PEG died from either pneumonia or septic shock.

Conclusions

The clinical course of pneumoperitoneum after PEG is not always benign and self-limiting. These findings suggest that clinicians should not neglect a moderate or large pneumoperitoneum, particularly in patients who have an altered mental status or received antibiotics, since peritoneal irritation cannot be observed under these circumstances.

Double-Balloon Enteroscopy in Elderly Patients: Is It Safe and Useful?: Dae Han Choi, Seong Ran Jeon, Jin-Oh Kim, Hyun Gun Kim, Tae Hee Lee, Woong Cheul Lee, Byung Soo Kang, Jun-Hyung Cho, Yunho Jung, Wan Jung Kim, Bong Min Ko, Joo Young Cho, Joon Seong Lee, Moon Sung Lee; Intest Res 2014;12(4):313-319. Published online October 27, 2014; DOI: https://doi.org/10.5217/ir.2014.12.4.313

Abstract PDF PubReader ePub

Background/Aims

Providers may be hesitant to perform double-balloon enteroscopy (DBE) in the elderly because the increased number of co-morbidities in this population poses a greater risk of complications resulting from sedation. There are limited data on the use of DBE in the elderly. Here, we assessed the safety and efficacy of DBE in the elderly compared to those in younger patients.

Methods

We retrospectively analyzed the medical records of 158 patients who underwent 218 DBEs. Patients were divided into an elderly group (age ≥65 years; mean 71.4±5.4; n=34; 41 DBEs) and a younger group (age <65 years; mean 39.5±13.5; n=124; 177 DBEs).

Results

In both groups, the most common indication for DBE was obscure gastrointestinal bleeding. Mucosal lesions (33.3% vs. 60.9%; P=0.002) were the most common finding in both groups, followed by tumors (30.8% vs. 14.1%; P=0.036). The elderly were more likely to receive interventional therapy (51.3% vs. 23.5%; P=0.001). The diagnostic yield of DBE was slightly higher in the elderly group (92.3% vs. 86.5%; P=0.422), but was not statistically significant. The therapeutic success rate of DBE was 100% in the elderly group compared to 87.5% in the younger group (P=0.536). The overall DBE complication rate was 1.8% overall, and this rate did not differ significantly between the groups (2.6% vs. 1.7%; P=0.548).

Conclusions

DBE is safe and effective in the elderly, and has a high diagnostic yield and high therapeutic success rate.

Abstract PDF PubReader

Background/Aims

Colorectal cancer (CRC) develops from colonic adenomas. Type 2 diabetes mellitus (DM) is associated with a higher risk of CRC and metformin decreases CRC risk. However, it is not certain if metformin affects the development of colorectal polyps and adenomas. This study aimed to elucidate if metforminaffects the incidence of colonic polyps and adenomas in patients with type 2 DM.

Methods

Of 12,186 patients with type 2 DM, 3,775 underwent colonoscopy between May 2001 and March 2013. This study enrolled 3,105 of these patients, and divided them in two groups: 912 patients with metformin use and 2,193 patients without metformin use. Patient clinical characteristics, polyp and adenoma detection rate in the two groups were analyzed retrospectively.

Results

The Colorectal polyp detection rate was lower in the metformin group than in the non-meformin group (39.4% vs. 62.4%, P<0.01). Colorectal adenoma detection rate was significantly lower in the metformin group than in the non-metformin group (15.2% vs. 20.5%, P<0.01). Fewer advanced adenomas were detected in the metformin group than in the non-metformin group (12.2% vs. 22%, P<0.01). Multivariate analysis identified age, sex, Body mass index and metformin use as factors associated with polyp incidence, whereas only metforminwas independently associated with decreased adenoma incidence (Odd ratio=0.738, 95% CI=0.554-0.983, P=0.03).

Conclusions

In patients with type 2 DM, metformin reduced the incidence of adenomas that may transform into CRC. Therefore, metformin may be useful for the prevention of CRC in patients with type 2 DM.

Abstract PDF

Background/Aims
Recent guidelines strongly recommend that the interval of surveillance colonoscopy be determined according to the risk stratification obtained at index colonoscopy. However, because of the differences in perception of the classification of colorectal intraepithelial neoplasia between Asian and Western countries, there is some confusion about surveillance colonoscopy. The aim of the present study was to evaluate the clinicopathological characteristics and the interval of surveillance colonoscopy between patients with high-grade dysplasia/carcinoma in situ and those with intramucosal carcinoma. Methods: From January 2003 to June 2010, 727 patients were included from 8 tertiary centers. Four hundred fifteen patients (57.1%) had high-grade dysplasia /carcinoma in situ (group A), and 312 (43.9%) had intramucosal carcinoma (group B). Clinicopathological data were reviewed retrospectively. Results: Group A had a significantly more frequent family history of colorectal cancer (3.1% vs. 0.6%, P<0.001), smaller polyp size (12 mm vs. 15 mm, P=0.001), and more proximal location (31.1% vs. 21.8%, P=0.005) than did group B. Among 727 patients, surveillance colonoscopy was performed within 6 months in 55.8% of patients and within 12 months in 77.8%. Group B had a significantly shorter interval of surveillance colonoscopy than did group A (P<0.001). There was no difference in detection of advanced neoplasia at surveillance colonoscopy between the 2 groups (6.6% vs. 5.4%, P=0.638). Conclusions: The recommended interval of surveillance colonoscopy is not followed in Korea. More education about post-polypectomy surveillance guidelines is required. (Intest Res 2013;11:276-282)

Analysis of Colonoscopy Quality in Clinical Practices of Korea: Cohort Study of Patients Referred to Tertiary Hospital after Colonoscopy Examinations: Chang Gyun Chun, Hyun Gun Kim, Seong Ran Jeon, Bong Min Ko, Byung Hoo Lee, Jin-Oh Kim; Intest Res 2013;11(3):198-203. Published online July 30, 2013; DOI: https://doi.org/10.5217/ir.2013.11.3.198

Abstract PDF

Background/Aims
Although the quality of colonoscopy is considered important to improve screening efficacy, there is little evidence and few statistical reports which properly reflects the colonoscopy quality of clinical practices in Korea. We aimed to investigate the quality indicators of colonoscopy performing in clinical practice. Methods: We analyzed the computerized photo-documentation files of patients who were transferred to tertiary academic hospital from private clinics or primary and secondary hospitals from January 2012 to October 2012. Quality indicators including cecal intubation rate, withdrawal time, bowel preparation status, colonoscopy report form were analyzed. Bowel preparation was assessed by 4 steps on the preparation scale (excellent, good, fair, poor). Results: A total of 198 patients (134 male, 64 female) were enrolled and analyzed. Cecal intubation rate was 91.4% (181/198) and photo-documentation of appendiceal orifice and ileocecal valve was achieved as 84.3% (167/198) and 71.7% (142/198), relatively. Overall, 83.3% of cases were adequate bowel preparation state (excellent 52%, good 31.3%). Withdrawal time could be estimated at 94.4% (187/198) of cases and mean withdrawal time of diagonostic colonoscopy (n=165) was 8.6 minutes. However, the rate of cases which withdrawal time was more than 6 minutes was 69.7% (115/165). Total of 30 institution's colonoscopy report forms were analyzed and among nearly half enrolled institutions (46.6%, 14/30) were just recording patient's information and colonoscopic diagnosis. Conclusions: Considerable portion of colonoscopy examination in the primary clinical practice has been performed with low procedure quality. We thus need careful attention to maintain the quality of colonoscopy in daily practice routines. (Intest Res 2013;11:198-203)

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)

Clinical Comparison for Colon Polyps between Right and Left Colon in Koreans: Wook Hyun Um, Hyun Gun Kim, Seong Ran Jeon, Tae Hee Lee, Wan Jung Kim, Bong Min Ko, Jin-Oh Kim, Joo Young Cho, Joon Seong Lee, Moon Sung Lee; Intest Res 2012;10(4):372-378. Published online October 31, 2012; DOI: https://doi.org/10.5217/ir.2012.10.4.372

Abstract PDF

Background/Aims
Comparative studies of colon polyps between right and left colon in Korean population are limited. We investigated the clinical characteristics of the patients according to polyp location and compared the results of the morphological and histological analysis of right and left colon polyps. Methods: The study was performed prospectively for the patients who underwent colon polypectomy for health check-ups in a single tertiary center. The patients were classified into three groups by the location of the polyps: right group (from the cecum to the splenic flexure), left group (from the descending colon to the anus), and total group. The size, the morphology, the location and the pathology of the polyps were evaluated. Results: From June 2010 to June 2011, Overall 2596 polyps from 950 patients (male=646) were analyzed. Colon polyps were right side-shift with increased patients age (P<0.001). The incidence of polyps was most common in sigmoid colon (26.5%). Polyps less than 5 mm size were more common in left colon (P<0.001) and flat polyps larger than 1 cm in right colon (P=0.006), respectively. In histopathological findings, the distribution of advanced adenoma was not different according to the location, however tubular adenomas and serrated adenomas (P<0.001) were more common in right colon. Female was more distributed in right group, respectively (P<0.001). Conclusions: In a single center study, colon polyps were more distributed in right colon with age and in females. Also flat polyps larger than 1cm, tubular adenoma and serrated adenoma were found in larger proportion in right colon. (Intest Res 2012;10:372-378)

Endoscopic Treatment Strategy for Large Laterally Spreading Tumor: Endoscopic Piecemeal Mucosal Resection or Endoscopic Submucosal Dissection: Sang Goo Kang, Suck-Ho Lee, Seung Kyu Chung, Jae Min Shin, Seong Ran Jeon, Tae Hee Lee, Hyun Gun Kim, Jin Oh Kim; Intest Res 2011;9(3):211-216. Published online December 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.3.211

Abstract PDF

Background/Aims
The therapeutic strategy between endoscopic piecemeal mucosal resection (EPMR) and endoscopic submucosal dissection (ESD) for large laterally spreading tumors (LSTs) has not been clearly defined. The aim of this study was to compare the clinical outcomes between EPMR and ESD in patients with large LST. Methods: From July 2006 to September 2010, 106 patients who underwent endoscopic resection for large (＞20 mm) LSTs were included in our retrospective analysis. Results: Baseline characteristics of the patients and tumors were not different between two groups except for location (EPMR-right colon, ESD-rectum). The en bloc resection rate and complete resection rate were significantly higher in the ESD group than those in the EPMR group (EPMR vs. ESD, 53.5% vs. 88.6, P＜0.01, 45.1% vs. 71.4%, P=0.01, respectively). However, total procedure time was significantly shorter in the EPMR group (21.3 min vs. 44.4 min, P＜0.01). Furthermore, the rates of complication including perforation and bleeding were significantly lower in the EPMR group than those in the ESD group (perforation, 1.4% vs. 11.4%, P=0.02; bleeding, 4.2% vs. 17.1%, P=0.03, respectively). During 19.9 months of follow-up, no significant difference was observed in terms of recurrence (1.5% vs. 3.2%). Non-granular, pseudo-depressed type (LST-PD) showed a significantly higher presence of adenocarcinoma and deeper submucosal invasion than other types of LSTs. Conclusions: The therapeutic strategy for choosing between EPMR and ESD for large LST lesions should be determined based on the macroscopic findings of their subtype. En bloc resection with ESD should be applied to LST-PDs due to their higher rate of submucosal invasion. (Intest Res 2011;9:211-216)

Capsule Endoscopy for Suspected Small Bowel Bleeding in Patients with Portal Hypertension: Gang Il Cheon, Jin Oh Kim, Sung Wook Hong, Seong Ran Jeon, Tae Hee Lee, Hyun Gun Kim, Won Young Cho, Wan Jung Kim, Min Jeong Kim, Sung Won Jeong, Jae Young Jang, Bong Min Ko, Joo Young Cho, Joon Seong Lee; Intest Res 2011;9(2):129-138. Published online August 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.2.129

Abstract PDF: Background/Aims
In Korea, limited data are available on small bowel bleeding in patients with portal hypertension. This study reports on the use of capsule endoscopy in cases of suspected small bowel bleeding in patients with portal hypertension. Methods: Capsule endoscopy was used at our hospital to evaluate small bowel disease in 501 cases from July 2003 to June 2010. Of those cases, nine patients with portal hypertension due to liver cirrhosis with suspected small bowel bleeding were selected for the study. A retrospective analysis was performed using data from medical records. Results: Six of the nine (66.7%) patients were males with an average age of 53.4 years. The average hemoglobin level was 8.1 g/dL. Abnormalities noted during capsule endoscopy included portal hypertensive enteropathy in all nine cases (100%), jejunal varices in four (44.4%), jejunal and ileal angiodysplasia in five (55.5%), multiple small bowel erosions in one (11.1%), granularity of the jejunal mucosa in one (11.1%), and small bowel erythema in three (33.3%). Active bleeding from jejunal varices was detected in two patients (22.2%). Despite having no obvious active bleeding during the capsule endoscopy, four patients (44.4%) were diagnosed with portal hypertensive enteropathy with obscure small bowel bleeding. Conclusions: Capsule endoscopy is a useful diagnostic tool for the evaluation of small bowel bleeding in patients with portal hypertensive enteropathy. Additional prospective and multicenter studies on the use of capsule endoscopy are needed to evaluate the incidence and clinical importance of portal hypertensive enteropathy.

Clinical Classification of Colorectal Epithelial Tumors and Proposal for Diagnostic Coding: Hyun Gun Kim, Jin-Oh Kim, Suck-Ho Lee, Chang Kyun Lee, Hyun Soo Kim, Hwang Choi, Dong-Hoon Yang, Bora Keum, Sung Pil Hong, Seong-Eun Kim, Byung Chang Kim, Jeong Eun Shin, Cheol Hee Park, Chang Soo Eun, Tae Il Kim, Dong Il Park, Kyu Chan Huh, Dong Kyung Chang, Seun Ja Park; Intest Res 2011;9(1):1-11. 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.
