Background/Aim. Endoscopic mucosal resection (EMR) or mucosectomy is an interventional procedure for minimal invasive endoscopic removal of benign and malignant digestive tract tumors. Mucosectomy removes flat and sessile neoplasms, early colorectal cancer (CRC) confined to mucosa or submucosa and lateral spreading tumors. The aim of the study was to show our first experience in application of this procedure in everyday practice in regarding completeness and efficacy of the procedure, complication rate and incidence of recurrent adenomas. Methods. In the prospective study 51 colorectal adenomas were removed in 44 patients by EMR. Results. Single mucosectomy was done in 43 patients, while multiple (8) in one patient. Complete resection was obtained in all procedures. In 36 (68.62%) procedures ?en block? resection was done, but in 15 (31.37%) procedures ?piece meal? resection was performed. Synchronous colorectal tumors (benign or malignant) were detected in 20 (45.45%) patients. Moderate dysplasia was found in 30 (58.82%) adenomas, but high grade dysplasia in 9 (17.64%) of adenomas. Intramucosal CRC was detected in 11.77% of adenomas. A total of 37 (72.54%) advanced adenomas were removed. There were 3 (5.88%) of recurrent adenomas, 6-30 months after the EMR. Only one (2.2%) case of post procedure bleeding was observed. Conclusion: EMR is a safe and efficious method for removal of flat, sessile adenomas, as well as early CRC. EMR is a routine endoscopic procedure in everyday practice of interventional endoscopist.

ABSTRACT BACKGROUND: Endoscopic mucosal resection is one of the most frequent therapeutic alternatives for large colorectal lateral spreading tumors. There are few data on the prevalence of synchronous lesions on these patients. OBJECTIVE: To describe the prevalence of synchronous colorectal lesions in patients referred for endoscopic mucosal resection of lateral spreading tumors >20 mm. METHODS: We reviewed the endoscopic database of our Department and identified adult patients who were referred for the resection of a colorectal lateral spreading tumor >20 mm and had a diagnostic colonoscopy performed up to six months before. The proportion of patients with at least one synchronous lesion was estimated. The following features were compared between patients with and without synchronous lesions: age, gender, bowel preparation quality and cecal intubation on index colonoscopy and therapeutic colonoscopy, serrated adenoma as index lesion. RESULTS: From December 2016 to November 2017, we identified 70 patients who fulfilled inclusion criteria. Median size of lesions was 25 mm (20-45). Eighty percent were located in the right colon and 35.71% were serrated adenomas. Synchronous lesion rate was 38.57%. Bowel preparation quality was similar in both groups when comparing both index and therapeutic colonoscopies. Patients with synchronous lesions had a higher proportion of serrated adenoma as index lesion than patients without synchronous lesions [51.85% vs 25.58%, OR 3.13 (1.13-8.68), P=0.03]. CONCLUSION: We found a high prevalence of synchronous lesions among patients with a large colorectal lateral spreading tumor. This risk seems to be increased if index lesions are serrated adenomas.

Risk Factors For Recurrence

Abstract Background and study aims Risk factors for colorectal adenoma recurrence after endoscopic mucosal resection (EMR) have been well documented. We assessed the efficacy of the newer 190 colonoscope versus the standard 180 colonoscope for complete resection of lateral spreading lesions. Patients and methods A single-center, retrospective study of patients who underwent EMR with Olympus 180 or 190 colonoscopes from January 1, 2010 to September 30, 2016. We included patients with lesions ≥ 20 mm and surveillance colonoscopy (SC1) after index EMR. A propensity score approach with inverse probability weighting was used to control for potential confounders. A secondary aim was to identify risk factors for recurrence and assess the applicability of the Sydney EMR recurrence tool (SERT) by grading each lesion of our cohort and analyzing associations with recurrence. Results Two hundred ninety-one lesions met inclusion criteria for the study. Odds ratio (OR) for recurrence with the 190 colonoscope was 1.06 (P = .85). Adenoma size (P = .02) and use of argon plasma coagulation (APC; P < .001) were risk factors for recurrence. Lesions with SERT scores > 0 had a higher recurrence risk during follow-up (32 % vs 21 %; OR 1.71; P = .05). Lesions with SERT scores = 0 reached a plateau for recurrence at 12 and 18 months in Kaplan-Meier curves. Conclusions The use of 190 colonoscopes did not measurably affect adenoma recurrence at SC1. Recurrence was associated with adenoma size, complementary APC for resection, and SERT scores > 0. Lesions with SERT scores = 0 that remain negative for recurrence at 18 months may return to routine surveillance.
