Effectiveness of clip-and-thread traction-assisted duodenal endoscopic submucosal dissection: a propensity score–matched study (with video)

Post written by Tomoaki Tashima, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. The indications for endoscopic submucosal dissection (ESD) in superficial nonampullary duodenal epithelial tumors (SNADETs) remain controversial because the procedure is technically challenging. The aim of this study was to compare the effectiveness of duodenal traction-assisted …

Endoscopic submucosal dissection using traction by a spring-and-loop with clip for a laterally spreading tumor in the inferior aspect of the cecum: a nonreferral center experience

Post written by Yohei Koyama, MD, from the Department of Gastroenterology and Hepatology, Tokyo Medical University Hospital, Tokyo, Japan. Endoscopic submucosal dissection (ESD) has been widely accepted as a minimally invasive treatment for early colorectal neoplasms. However, cecal ESD remains a challenging treatment owing to the anatomical features of the cecum, such as the thin …

Endoscopic submucosal dissection for a laterally spreading ampullary carcinoma

Post written by Osamu Dohi, MD, PhD, from Molecular Gastroenterology and Hepatology, Kyoto Prefectural University of Medicine Graduate School of Medical Science, Kyoto, Japan. We performed endoscopic submucosal dissection (ESD) for a laterally spreading ampullary carcinoma 3 cm in size because it was expected to be difficult to completely resect the lesion by endoscopic papillectomy …

Endoscopic full-thickness resection of colorectal lesions: a systematic review and meta-analysis

Post written by Russell D. Dolan, MD, from the Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, USA. As techniques have advanced to improve endoscopic removal of large lesions within the colon and rectum to serve as alternatives to surgery, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection …

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 …
