Novel approach to endoluminal antral gastroplasty using a modified gastrostomy tube and laparoscopic stapler.

Overview

BACKGROUND AND AIMS: In this study we demonstrated a novel approach to endoluminal antral gastroplasty using a transgastric trocar (Endo-TAGSS, Shawnee, Kans, USA) and laparoscopic noncutting stapler. METHODS: This was a nonsurvival study performed successfully in 2 domestic pigs. After placement of the Endo-TAGSS device, a laparoscopic stapler was introduced through the trocar and used to place staples along the anterior wall, greater curvature, and posterior wall, resulting in imbrication and reduction of the gastric antrum. Postprocedure, a diagnostic necropsy was performed. RESULTS: The endoluminal antral gastroplasty was performed successfully without immediate adverse events. CONCLUSIONS: Endo-TAGSS-assisted endoscopy can overcome limitations of current endoscopic techniques by allowing the use of larger diameter laparoscopic surgical devices in endoscopy, which permitted antral gastroplasty in this study.
