OBJECTIVES: Serrated polyps, which are considered to be precursors of colorectal carcinoma, include hyperplastic polyps, sessile serrated adenomas and traditional serrated adenomas. With the exception of hyperplastic polyps, all of these lesions must be removed. This study sought to examine whether underwater endoscopic mucosal resection is a safe and effective technique for treating serrated polyps.
METHODS: Cases in which patients were submitted for underwater endoscopic mucosal resection and histologically diagnosed with sessile serrated adenoma were prospectively registered.
RESULTS: The median patient age was 54.5 years (range, 48 to 72 years), and the patients included 4 men (28.5%) and 10 women (71.5%). One lesion (6.2%), 10 lesions (62.5%), 1 lesion (6.2%), 3 lesions (18.8%) and 1 lesion (6.2%) were found in the cecum, the ascending colon, the hepatic flexure, the transverse colon and the descending colon, respectively. The median lesion size was 20 mm (range, 10 to 35 mm). Eight lesions (50%) were removed en bloc, and the remaining eight lesions (50%) were removed using a piecemeal technique. None of the cases were complicated by perforation or delayed bleeding.
CONCLUSION: Underwater resection could be a feasible, safe and effective alternative for the resection of sessile serrated adenomas.
