Serosal and muscular layers incision technique in laparoscopic surgery for gastric gastrointestinal stromal tumors

Abstract

Introduction

To minimize the resection of stomach tissue, especially for lesions close to the esophagogastric junction or pyloric ring, we developed laparoscopic wedge resection with the serosal and muscular layers incision technique (SAMIT) for gastric gastrointestinal stromal tumors.

Materials and Surgical Technique

SAMIT involves resection of the mucosal and submucosal layers and then an incision in serosal and muscular layers around the tumor. SAMIT is simple and does not require special devices. The data of 13 patients who underwent laparoscopic wedge resection with SAMIT for primary gastric gastrointestinal stromal tumors were reviewed. No intraoperative complications were observed, and postoperative stenosis occurred in only one case of a middle stomach lesion. Adequate oncological resection was performed in all cases.

Discussion

Laparoscopic wedge resection with SAMIT is technically and oncologically safe. It is useful for treating gastric gastrointestinal stromal tumors, including those close to the esophagogastric junction or pyloric ring.
