New linear stapled semimechanical esophagogastric anastomosis with invagination

Abstract

Objective. Development and implementation esophagogastric linear stapled semimechanical anastomosis with invagination. Material and methods. Seromuscular stitches are applied over 4 cm on both sides to the lateral surfaces of the esophagus posterior wall and gastric graft posterior wall, towards their edges. The posterior wall of the anastomosis is sutured and cutted with a linear stapler on 30–40 mm deep. The anterior wall sutured with a linear stapler. The next layer of sutures on the anastomosis anterior wall invaginates the anastomos and the esophageal stump into the gastric graft. Results. There was no early postoperative mortality. Average I. Lewis minimally invasive esophagectomy time was 353 minutes (245–470 minutes). The average volume of blood loss was 114 mL (50–200 mL). No patient faced an anastomotic leak. Anastomotic stricture occurred in 5 patients (19.2%) during 21 days to 6 months of follow-up. There were no anastomosis-related complications above Clavien-Dindo grade II. Conclusions. Linear stapled semimechanical anastomosis with invagination has proven both clinical and technical advantages of its use.
