Hybrid resection of GI stromal tumor with endoscopic submucosal dissection and the full-thickness resection device

Post written by Varun Angajala, MD, MS, and Ara Sahakian, MD, from the Department of Internal Medicine, Keck School of Medicine, University of Southern California, Los Angeles, California, USA. We are excited to share our hybrid resection technique for a gastric subepithelial lesion (SEL). We performed submucosal dissection to unroof and expose the surface of the …

Use of a novel dual-action clip for closure of complex endoscopic resection defects

Post written by Mike Tzuhen Wei, MD, from Stanford University, Stanford, California, and Veterans Affairs Palo Alto, Palo Alto, California, USA. In our presentation, we demonstrate the use of a dual-action clip and clips with atraumatic teeth in facilitating the closure of endoscopic submucosal dissection defects. We found that the dual-action clip (Micro-Tech Endoscopy USA, Ann …

Tip-in EMR as an alternative to endoscopic submucosal dissection for 20- to 30-mm nonpedunculated colorectal neoplasms

Post written by Kazunori Takada, MD, and Kinichi Hotta, MD, from the Division of Endoscopy, Shizuoka Cancer Center, Shizuoka, Japan. Compared with conventional EMR, endoscopic submucosal dissection (ESD) provides a higher en-bloc resection rate and a lower local recurrence rate for large lesions. However, ESD is technically demanding and associated with a higher risk of adverse …

Endoscopic submucosal dissection with reinforcement using a laparoscopic approach for a duodenal cavernous hemangioma

Post written by Yoriaki Komeda, MD, PhD, from the Department of Gastroenterology and Hepatology, Kindai University Faculty of Medicine, Osaka, Japan. We performed endoscopic submucosal dissection (ESD) with reinforcement using a laparoscopic approach (duodenal-laparoscopic and endoscopic coordinated surgery [D-LECS] with ESD) for a duodenal cavernous hemangioma. Cavernous hemangiomas including duodenum are derived from the submucosa. Even …

Possibility of ultrathin endoscopy in radial incision and cutting for esophageal strictures

Post written by Mako Koseki, MD, and Daisuke Kikuchi, MD, PhD, from the Department of Gastroenterology, Toranomon Hospital, Tokyo, Japan. In this video, we present a case of a refractory esophageal stricture caused by anastomosis of gastric tube reconstruction for advanced esophageal carcinoma. We treated the stricture with radial incision and cutting (RIC) using ultrathin endoscopy. …

Endoscopic submucosal dissection in the right lateral position for early gastric cancer in the fornix

Post written by Hiromu Fukuda, MD, from the Department of Gastroenterology and Hepatology, Osaka University Graduate School of Medicine, Suita, Japan. In this video case, we show the usefulness of endoscopic submucosal dissection (ESD) in the right lateral position (RLP) for early gastric cancer (EGC) in the fornix. ESD of EGC in the fornix is challenging …

Technical feasibility of salvage endoscopic submucosal dissection after chemoradiation for locally advanced rectal adenocarcinoma

Post written by Galen Leung, MD, from the Department of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA. For this study, we wanted to evaluate the technical feasibility of salvage endoscopic submucosal dissection (ESD) after chemoradiation for locally advanced rectal adenocarcinoma in terms of rates of complete resection of residual tumor and safety profile. Emerging evidence …

Endoscopic submucosal dissection with ductotomy for the resection of a gastric duplication cyst with a communicating duct

Post written by Hiroyuki Aihara, MD, PhD, from the Division of Gastroenterology Hepatology and Endoscopy, Brigham and Women’s Hospital, Boston, Massachusetts, USA. A 40-year-old woman with persistent upper abdominal pain was found to have a 3-cm subepithelial lesion in the prepyloric area and was referred to our center. EUS showed an anechoic cyst in the …

Efficacy and safety comparison of scissor-type knives with needle-type knives for colorectal endoscopic submucosal dissection: a post-hoc propensity score–matched analysis (with videos)

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 primarily focused on the safety of colorectal endoscopic submucosal dissection (ESD) using a scissor-type knife in comparison to a needle-type knife. For more information, please visit our …

A specimen collection technique to ensure that the resected specimen is safely retrieved after duodenal endoscopic submucosal dissection

Post written by Marie Kurebayashi, MD, from the Department of Gastrointestinal Endoscopy, NTT Medical Center Tokyo, Tokyo, Japan. This video describes the collection method for duodenal specimens resected by endoscopic submucosal dissection (ESD). With this method, we leave a thin bundle of about 1 mm of submucosal fibers for the linkage of the resected specimen …
