Post written by Siyu Sun MD, PhD, and Ye Han MD, PhD, from the Endoscopic Center, Shengjing Hospital of China Medical University, Shenyang, China. Esophageal stenosis is closely associated with quasi-circumferential endoscopic submucosal dissection (ESD). We examined whether post-ESD esophageal stricture can be prevented by grafting an acellular dermal matrix (ADM) membrane in a large …

ESD by use of a modified dental floss clip method for recurrent tumor in the cecum
Post written by Hisatomo Ikehara, MD, PhD, from the Division of Gastroenterology and Hepatology, Department of Medicine, Nihon University School of Medicine, Tokyo, Japan. The patient in this video case underwent endoscopic submucosal dissection (ESD) for a recurrent tumor in the cecum 11 months after initial piecemeal endoscopic mucosal resection (p-EMR). The recurrent tumor showed …

Insulated tip knife tunneling technique with clip line traction
Post written by Seiichiro Abe, MD, from the Endoscopy Division, National Cancer Center Hospital, Tokyo, Japan. A 80-year-old male underwent endoscopic submucosal dissection (ESD) for a circumferential esophageal squamous cell carcinoma, 70 mm in size, involving the middle and lower esophagus. Using a dual knife and IT knife nano, a semi-circumferential mucosal incision was made …

Usefulness and safety of a scissors-type knife in ESD for non-ampullary duodenal epithelial tumors
Post written by Toshio Kuwai, MD, PhD, from the Department of Gastroenterology, National Hospital Organization, Kure Medical Center and Chugoku Cancer Center, Kure, Japan. In this study, we describe 2 cases of duodenal endoscopic submucosal dissection (ESD) using a scissors-type knife, Stag Beetle (SB) Knife Junior (Jr) (Sumitomo Bakelite Co., Tokyo, Japan). Our first case …
Management and risk factor of stenosis after ESD for colorectal neoplasms
Post written by Takemasa Hayashi, MD, from the Digestive Disease Center, Showa University Northern Yokohama Hospital, Yokohama, Japan. This study focuses on the incidence of stenosis and its relationship with the clinicopathological factors in surveillance. Endoscopic submucosal dissection for large colorectal neoplasms can reduce the need for unnecessary surgery. Large mucosal lesions should be removed …

ESD with a scissors-type knife for post-EMR recurrence tumor
Post written by Toshio Kuwai, MD, from the Department of Gastroenterology, National Hospital Organization, Kure Medical Center and Chugoku Cancer Center in Hiroshima, Japan. Endoscopic submucosal dissection (ESD), although routinely performed, can prove to be challenging in areas where endoscopic mucosal resection (EMR) has already been performed because of scarring and fibrosis. A 79-year-old woman …

“Underwater” ESD for superficial esophageal neoplasms
Post written by Tomofumi Akasaka from the Department of Gastrointestinal Oncology at Osaka Medical Center for Cancer and Cardiovascular Disease. In this study, we used a bipolar needle-knife with a water jet function (Jet B-knife; Zeon Medical, Tokyo, Japan). After a circumferential incision, as performed for conventional ESD, esophageal lumen was filled and submucosal injection with …
