Safe management of laparoscopic endoscopic cooperative surgery for superficial non-ampullary duodenal epithelial tumors

Abstract

Background and study aims Endoscopic submucosal dissection (ESD) for duodenal tumors results in a high delayed perforation rate due to the thinness of the duodenal wall. In most cases with perforation after duodenal ESD, additional surgery is needed due to severe peritonitis. A newly developed procedure, laparoscopic endoscopic cooperative surgery for duodenal tumors (D-LECS), may help to avoid perforation after ESD. In our institution, patients with superficial non-ampullary duodenal epithelial tumors (SNADET) smaller than 50 mm which could not have en-bloc resection by endoscopic mucosal resection were treated with D-LECS. After a laparoscopic exposure of anterior duodenal wall of second portion, ESD was performed. Laparoscopic suturing from the serosal side of ESD site was performed for reinforcement. There were neither postoperative leakage nor other complications. Therefore, D-LECS can be performed safely and prevent perforation after ESD for SNADET. D-LECS could be selected as a treatment for SNADET which can be cured by ESD.
