ESD removal of submucosal embedded fish bone in the esophagus

Post written by Hon Chi Yip from the Division of Upper Gastrointestinal and Metabolic Surgery at Prince of Wales Hospital at the Chinese University of Hong Kong. This video demonstrated successful removal of a fish bone that was deeply embedded inside the submucosa of proximal esophagus using the endoscopic submucosal dissection (ESD) technique. This video …

ESD removal of large superficial tumor

Post written by Maiko Takita, MD, from the Department of Gastroenterology, NTT Medical Center Tokyo, in Tokyo, Japan Endoscopic resection for cecal tumors extending to the appendiceal orifice is difficult because the margin cannot be often tracked entirely, in addition to the higher risk of perforation. Here we report a case of a colonic tumor …

Countertraction in ESD

Post written by Hiroyuki Aihara, MD, PhD from the Division of Gastroenterology, Hepatology, and Endoscopy at Brigham and Women’s Hospital, Harvard Medical School, in Boston, Massachusetts, USA Two technically challenging endoscopic submucosal dissection (ESD) cases are described in this video. The first gastric ESD was complicated by prior tattooing and incomplete resection, which caused significant …

Submucosal tunneling technique using insulated-tip knife in complete circumferential endoscopic submucosal dissection

Kenichiro Imai from the Division of Endoscopy, Shizuoka Cancer Center presents this video case. We demonstrated complete circumferential colorectal endoscopic submucosal dissection (ESD) using an insulated-tip knife. Colonoscopy in a 70-year-old woman showed a 15-cm circumferential laterally spreading tumor (LST) in the upper rectum. Through the use of magnified endoscopy, we diagnosed non-invasive cancer, so we …
