Intestinal topical lidocaine spray improves the efficacy and safety of endoscopic sigmoid polypectomy.

Background And Aims: Endoscopic polypectomy can prevent colorectal cancer. Adequate surgical field visualization is crucial to complete resection. To prevent visual field loss caused by intestinal peristalsis, we investigated the efficacy and safety of topical lidocaine spraying during the endoscopic sigmoid polypectomy (ESP).
