简要总结
Patients who have provided informed consented and are scheduled to undergo endoscopic mucosal resection (EMR) of lesions 15mm and larger will be randomized to STSC (80 W, Effect 5) vs APC (preferred settings) vs No Treatment of the perimeter of the EMR site.
详细描述
Data regarding polyp morphology, location & shape will be recorded in addition to procedure and treatment length. Injection fluid use and clipping will also be recorded in addition to any procedural complications.
All randomized subjects will receive a 30-day post procedure follow-up phone call and be scheduled, as per the standard of care, to receive a standard follow-up colonoscopy procedure after the initial procedure. The investigators will measure the rate of recurrence by endoscopic visualization of the EMR site at the first follow-up using endoscopic magnification and electronic chromoendoscopy, as well as systematic biopsy of the scars.

结局指标
主要结局
Types of Recurrences
时间窗: 1 day
Description of whether recurrence was visible during the follow-up procedure and confirmed by pathology, visible during the follow-up procedure but not confirmed by pathology, or not visible during the follow-up procedure but confirmed by pathology of biopsies taken.
Recurrence
时间窗: 1 day
The recurrence rate of adenomas at the site of any qualifying, previously resected lesions will be measured at the first follow-up colonoscopy
