A modified endoscopic full-thickness resection for gastrointestinal stromal tumors: A new closure technique based on the instruction of super minimally invasive surgery.

Abstract

Endoscopic resection, including endoscopic submucosal excavation (ESE) and endoscopic full-thickness resection (EFTR), is an effective and safe method for gastrointestinal stromal tumors (GISTs). While during traditional EFTR, closure of the defect using a loop-and-clip closure technique or just clips always follows the full-thickness resection, this usually results in the occurrence of gas-related complications, such as pneumoperitoneum [1] [2]. What is more, it is time-consuming and not easy to perform for some lesions larger than 2.0 cm.
