Safety and Efficacy of Endoscopic Submucosal Dissection for Non-Ampullary Duodenal Neoplasms: A Case Series

description Sixteen non-ampullary duodenal neoplasms in 16 patients were treated with endoscopic submucosal dissection (ESD) performed by an endoscopist and an instrument assistant between February 2011 and November 2014. En bloc resection was performed in 15 cases (94%); lateral and vertical margins were pathologically free in 13 cases. Perforation occurred during submucosal dissection using a flex knife, but no perforations occurred in 15 cases using the hook knife only. No postoperative bleeding nor recurrence has been reported in any patient during the median 17-month follow-up period. Use of the hook knife as the main instrument and targeted training of the endoscopist and instrument assistant contributed to safe and effective duodenal ESD for non-ampullary duodenal neoplasms.
