A Study On A Laparoscopic Surgical Procedure For Delayed Perforation After Gastric Endoscopic Submucosal Dissection

Abstract

Delayed perforation after gastric endoscopic submucosal dissection (ESD) has been reported to have large pore size when it has occurred, is difficult to close directly. And also, it is reported that emergency surgery is often required. We experienced three cases of emergency laparoscopic surgery for delayed perforation after gastric ESD. It is believed that the cause of the delayed perforation may be necrosis of the muscular layer due to excessive current applied to the muscular layer during hemostasis. Since the tissue around the perforated area becomes weak due to necrosis, gastric resection is often required.
