Video 1Endoscopic submucosal dissection (ESD) of large rectal lateral spreading tumors (LSTs) that extend to the dentate line with internal hemorrhoids is a challenging procedure because of the increased risk of bleeding from penetrating and hemorrhoidal vessels and the reduced visual field caused by the dilated venous packages and the narrow anal lumen.This video describes novel technical approaches to minimize the risk of intraoperative bleeding.The described approaches are indicated in large  ...[more]
