Abstract

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.

Abstract

Colonoscopic polypectomy is effective in decreasing the incidence and mortality of colorectal cancer (CRC). Premalignant polyps discovered during colonoscopy are associated with the risk of metachronous advanced neoplasia. Postpolypectomy surveillance is the most important method for managing advanced metachronous neoplasia. A more efficient and evidence-based guideline for postpolypectomy surveillance is required because of the limited medical resources and concerns regarding colonoscopy complications. In these consensus guidelines, an analytic approach was used to address all reliable evidence to interpret the predictors of CRC or advanced neoplasia during surveillance colonoscopy. The key recommendations state that the high-risk findings for metachronous CRC following polypectomy are as follows: adenoma ≥10 mm in size; 3 to 5 (or more) adenomas; tubulovillous or villous adenoma; adenoma containing high-grade dysplasia; traditional serrated adenoma; sessile serrated lesion containing any grade of dysplasia; serrated polyp of at least 10 mm in size; and 3 to 5 (or more) sessile serrated lesions. More studies are needed to fully comprehend the patients who are most likely to benefit from surveillance colonoscopy and the ideal surveillance interval to prevent metachronous CRC.

Abstract

Background and Aims Metabolic syndrome may share the pathophysiology of adipose tissue dysregulation and inadequate immune response with inflammatory bowel disease [IBD]. We determined the association of abdominal obesity [AO] with the risk of developing IBD. Methods We conducted a nationwide population-based cohort study using the Korean National Health Insurance Services database. A total of 10 082 568 participants of the 2009 national health screening programme were enrolled. Newly diagnosed Crohn's disease [CD] and ulcerative colitis [UC] were identified using the International Classification of Diseases 10th Revision and specialized national codes for rare intractable diseases. Waist circumference [WC] was classified into six groups and compared with the reference values of 85.0–89.9 cm for men and 80.0–84.9 cm for women. AO was defined as a WC of ≥90 cm for men and ≥85 cm for women. Results During a median follow-up of 9.3 years, the incidence rates of CD and UC were 2.11 and 8.40 per 100 000 person-years, respectively. After adjustment for age, sex, lifestyle behaviours, income and body mass index [BMI], the increase in baseline WC was significantly associated with the risk of developing CD, but not UC, compared to the references. The risk of developing CD in subjects with AO increased significantly compared to those without AO [adjusted hazard ratio, 1.40; 95% confidence interval, 1.21–1.61], regardless of obesity based on BMI. Conclusions Individuals with AO bore an increased risk of developing CD proportional to WC, but not UC, suggesting that visceral adiposity is related to the pathophysiology of CD.
