BACKGROUND: We aimed to evaluate the safety and technical success of an easy-to-use technique that applies underwater cap suction pseudopolyp formation to facilitate the resection of flat lesions or those at the appendiceal orifice or ileocecal valve.
METHODS: We retrospectively analyzed a register of consecutive cap suction underwater endoscopic mucosal resection (CAP-UEMR) procedures performed at two centers between September 2020 and December 2021. Procedures were performed using a cone-shaped cap, extending 7 mm from the endoscope tip, to suction the lesion while submerged underwater, followed by underwater snare resection. Our primary end point was technical success, defined as macroscopic complete resection.
RESULTS: We treated 83 lesions (median size 20 mm; interquartile range [IQR] 15-30 mm) with CAP-UEMR: 64 depressed or flat lesions (18 previously manipulated, 9 with difficult access), 11 from the appendix, and 8 from the ileocecal valve. Technical success was 100 %. There were seven intraprocedural bleedings and two delayed bleedings, all managed endoscopically. No perforations or other complications occurred. Among the 64 lesions with follow-up colonoscopy, only one recurrence was detected, which was treated endoscopically.
CONCLUSIONS: CAP-UEMR was a safe and effective technique for removing nonpolypoid colorectal lesions, including those arising from the appendiceal orifice or ileocecal valve.
