Risk Factors For Recurrence

Abstract Background and study aims Cold snare endoscopic mucosal resection (EMR) is being increasingly utilized for non-pedunculated polyps ≥ 20 mm due to adverse events associated with use of cautery. Larger studies evaluating adenoma recurrence rate (ARR) and risk factors for recurrence following cold snare EMR of large polyps are lacking. The aim of this study was to define ARR for polyps ≥ 20 mm removed by cold snare EMR and to identify risk factors for recurrence. Patients and methods A retrospective chart review of colon cold snare EMR procedures performed between January 2015 and July 2019 at a tertiary care medical center was performed. During this period, 310 non-pedunculated polyps ≥ 20 mm were excised using cold snare EMR with follow-up surveillance colonoscopy. Patient demographic data as well as polyp characteristics at the time of index and surveillance colonoscopy were collected and analyzed. Results A total of 108 of 310 polyps (34.8 %) demonstrated adenoma recurrence at follow-up colonoscopy. Patients with a higher ARR were older (P = 0.008), had endoscopic clips placed at index procedure (P = 0.017), and were more likely to be Asian and African American (P = 0.02). ARR was higher in larger polyps (P < 0.001), tubulovillous adenomas (P < 0.001), and polyps with high-grade dysplasia (P = 0.003). Conclusions Although cold snare EMR remains a feasible alternative to hot snare polypectomy for resection of non-pedunculated polyps ≥ 20 mm, endoscopists must also carefully consider factors associated with increased ARR when utilizing this technique.

Aim: to identify risk factors for neoplasms recurrence removed by endoscopic mucosal resection (EMR).Patients and methods: the single-center retrospective observational study included 207 patients with 260 benign colon neoplasms. There were 95 (45.9%) males and 112 (54.1%) females. The median age of the patients was 67 (27-80) years. The results obtained were assessed using following criteria: morbidity rate, complication type, hospital stay, tumor site, number of neoplasms in colon, lateral growth, fragmentation rate, technical difficulties (mucosal fold convergence)during surgery, grade of dysplasia, recurrence rate.Results: intraoperative fragmentation of the neoplasms during mucosectomy occurred in 48/260 (18.5%) cases. Postoperative complications within the period of up to 30 days occurred in 13/207 (6.3%) patients. The most frequent 9 (4.2%) postoperative complication arising after mucosectomy was post-polypectomy syndrome. Another 4 (2.0%) patients produced bleeding after the surgery, which required repeated endoscopic procedure. No mortality occurred. The tumor size exceeding 25 mm (Exp (B) = 0.179; 95% CI = 0.05-0.7; p = 0.014), severe dysplasia (Exp (B) = 0.113; 95% CI = 0.03-0.4; p = 0.001) and fold convergence (Exp (B) = 0.2; 95% CI = 0.07-0.7; p = 0.015) are independent risk factors for disease recurrence.Conclusion: mucosectomy is indicated for colon adenomas if its size does not exceed 25 mm and can be removed en bloc.

Abstract Background Colonoscopy is associated with a risk of peritonitis in patients on peritoneal dialysis. However, no study has yet described the risk factors in play. Methods This was a retrospective multicentre study. The medical records of patients on continuous ambulatory peritoneal dialysis (CAPD) who underwent colonoscopy from January 2003 to December 2012 were analysed. We recorded demographic characteristics, colonoscopic factors, use of prophylactic antibiotics, and development of peritonitis. Colonoscopy-related peritonitis was defined as peritonitis developing within 1 week after colonoscopy. Demographic and clinical characteristics were compared between patients who did and those who did not develop peritonitis. Results During the study period, 236 patients on CAPD underwent colonoscopy, of whom 9 (3.8%) developed peritonitis. The rates of polypectomy/endoscopic mucosal resection were significantly higher in the peritonitis group than in the no peritonitis group (66.7 vs. 23.4%, p = 0.009). Prophylactic antibiotics were prescribed before colonoscopy in 65 patients; none developed peritonitis. No patient who developed peritonitis received prophylactic antibiotics (p = 0.067). Conclusions Advanced procedures including polypectomy or endoscopic mucosal resection increase colonoscopy-related peritonitis in patients on CAPD. Randomized controlled trials to investigate whether prophylactic antibiotics are needed to prevent peritonitis in all CAPD patients are warranted.
