Laparoscopic transgastric resection of gastric submucosal tumor located near the esophagogastric junction

Abstract

Aim: Laparoscopic wedge resection is widely accepted as the choice of treatment for gastric submucosal tumors (GST). However, tumors on the posterior wall at the esophagogastric junction (EGJ) are difficult to approach. Laparoscopic transgastric resection (LTR) is a novel technique to remove gastric tumors that are unresectable by endoscopy due to their size and location. The aim of the article is to assess the feasibility and oncological outcomes of this laparoscopic approach for intraluminal GST located in the posterior wall and near the EGJ.

Methods: A retrospective analysis of all patients with GST located at the EGJ who underwent LTR at our institution from January 2015 to February 2016 was performed.

Results: Of the 4 patients who underwent LTR, 3 were female and 1 was male, with a mean age of 74.5 years. LTR was successfully performed in all the cases. All patients received a complete resection with negative margins. Histopathologic diagnoses were gastrointestinal stromal tumor in 2 cases and leiomyoma in the other 2. Median tumor size was 3.45 cm. The mean operation time was 173 min (range 120-232 min). One patient experienced a postoperative hematemesis, but was treated conservatively. The mean postoperative stay was 8 days (range 4-15 days).

Conclusion: LTR is feasible and difficult localizations can be reached with ease. It is an appropriate alternative to laparoscopic wedge resections especially for localizations that cannot be accessed by laparoscopy such as tumors located near the EGJ.
