Modified double-layered suturing for a mucosal defect after colorectal endoscopic submucosal dissection (Origami method) (with video)

Post written by Teppei Masunaga, MD, and Motohiko Kato, MD, PhD, from the Division of Research and Development for Minimally Invasive Treatment, Cancer Center, Keio University School of Medicine, Tokyo, Japan. Endoscopic defect closure techniques have been applied to reduce the incidence of adverse events after colorectal endoscopic submucosal dissection (ESD). This retrospective observational study aimed …

Usefulness of the ultrathin endoscope with a newly developed knife for complex esophageal endoscopic submucosal dissection

Post written by Satoki Shichijo, MD, PhD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. A 62-year-old woman underwent subtotal esophagectomy for esophageal cancer, local resection of pharyngeal cancer with postoperative radiotherapy, and bilateral cervical lymph node dissection because of pharyngeal cancer metastasis. Follow-up endoscopy revealed a 10-mm brownish area in the …

Closure of large mucosal defects for prevention of strictures after duodenal endoscopic submucosal dissection (with video)

Post written by Yoko Kubosawa, MD, from the Division of Gastroenterology and Hepatology, Department of Internal Medicine, and the Division of Research and Development for Minimally Invasive Treatment, Cancer Center, Keio University School of Medicine, Tokyo, Japan. We analyzed the incidence of post–endoscopic submucosal dissection (ESD) strictures after wide-field duodenal ESD. Although it is known that …

Endoscopic submucosal dissection of a gigantic gastric polyp aided by a novel retraction device and complicated by upper esophageal sphincter laceration during retrieval

Post written by Michael Lajin, MD, from Sharp HealthCare, San Diego, California, USA. An 87-year-old woman with multiple comorbidities was found to have a gigantic gastric polyp (11 × 8 cm) with a broad short stalk containing an area of irregular vascular patterns worrisome for high-grade dysplasia. Attempting polypectomy using an endoloop was challenging because of the …

Emergent endoscopic submucosal dissection for a polypoid fibroadipose tumor accidentally disgorged from the mouth: an organ-preserving minimally invasive treatment

Post written by Yuki Morita, MD, and Toshiyuki Yoshio, MD, PhD, from the Department of Gastroenterology, Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan. An unusual, long polyp was detected extending from the hypopharynx to the lower thoracic esophagus of a patient. Polypoid fibroadipose tumors should be resected because they are occasionally malignant and …

Endoscopic adventitial dissection of a rectal GI stromal cell tumor

Post written by Hao Dang, BSc, and Jurjen J. Boonstra, MD, PhD, from the Department of Gastroenterology and Hepatology, Leiden University Medical Center, Leiden, The Netherlands. Endoscopic submucosal dissection has allowed the endoscopist to perform en bloc resection of various types of GI neoplasms, including subepithelial tumors (SETs). However, submucosal dissection is not feasible for SETs …

Endoscopic submucosal dissection of appendiceal lesions by using a novel adjustable traction device: A-TRACT-2

Post written by Louis-Jean Masgnaux, MR, from the Gastroenterology and Endoscopy Unit, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France. We describe the use of an adjustable endoscopic traction system, the A-TRACT-2, a handmade device that can be tightened during the procedure to increase the traction tension and greatly assist the operator in difficult cases …

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 …
