Non-Exposed Endoscopic Wall-inversion Surgery for Submucosal Tumor of the Duodenum: A Novel Case Report

Abstract

Laparoscopic and endoscopic cooperative surgery for duodenal tumor is the precise oncologic resection procedure and the closure of the defect (1). Non-exposed Endoscopic Wall-inversion Surgery (NEWS) is a novel minimally invasive technique for gastric submucosal mass (SMT) and early gastric cancer having advantageous precision to determine the resection line with no risk of peritoneal contamination (2-5). We describe the NEWS technique that we applied and performed for a small duodenal SMT.
