A Modified Esophagogastric Reconstruction Method After Laparoscopic Proximal Gastrectomy

Anastomosis Clinical Trial

Official title:
A Modified "Arch-bridge-type" Esophagogastric Reconstruction Method After Laparoscopic Proximal Gastrectomy

Clinical Trial Summary

The double-flap technique (DFT) is an effective digestive tract reconstruction method after proximal gastrectomy (PG) to reduce the incidence of postoperative reflux esophagitis. But its clinical application is restricted due to the technical complexity. Our surgical team devise a modified esophagogastric reconstructive method which we term the "arch-bridge-type" reconstruction based on the principle of DFT. The aim of this single-arm prospective study is to assess the safety and feasibility of the "arch-bridge-type" reconstruction after PG.

Clinical Trial Description

1. The lymphadenectomy is performed according to the Japanese Gastric Cancer Treatment Guidelines. 2. Transection of the esophagus is performed using a linear stapler 2cm away from the proximal end of the tumor. 3. Creating the seromuscular flap ("arch-bridge"): (1) The stomach is resected by a linear stapling device. (2) A "匚" shaped seromuscularflap (3.0cm×4.0cm) is created utilizing electrocautery extracorporeally by dissecting submocosal and muscular layer of the anterior wall of the remnant stomach. (3) The opening of the flap is interrupted sutured by 4-0 absorbable suture, then the "arch-bridge" is created. 4.The remnant stomach is then inserted into the abdominal cavity, and pneumoperitoneum is re-established to perform the intracorporeal anastomosis. ;
