Endoscopic Full-thickness Resection for Gastric Submucosal Tumor: A Technical Analysis Study (With Video).

ABSTRACT:

Background

Endoscopic full-thickness resection (EFTR) is an effective treatment method for gastric submucosal tumors (SMTs). We aimed to perform a technical analysis of EFTR in gastric SMT and compare it with the outcome parameters.

Method

Sixty-one gastric SMTs from 60 patients were resected using EFTR. The indication criteria: size, 11-30 mm, connection to the muscularis propria on endoscopic ultrasonography, intraluminal growth type, no ulceration, and histologically evident or clinically suspicious gastrointestinal stromal tumors (GISTs). The following technical improvements were introduced during the study Periods 1-3: routine use of clip-line traction (Periods 1-3); use of a plastic bag retriever (Periods 2-3); adaptation of the reopenable clip over-the-line method (RO
