Gastrotomy with anvil “dunk”: a novel technique for gastrojejunostomy in the patient undergoing laparoscopic Roux-en-Y gastric bypass

Abstract

Gastrotomy with anvil dunk is a reproducible and safe method for constructing the gastrojejunostomy. It is an advanced laparoscopic technique that closely resembles open surgical techniques and provides a safe alternative to existing methods.

Transoral Technique for Gastrojejunostomy in Laparoscopic Roux-en-Y Gastric Bypass (LRYGBP) Can Accelerate Learning Curve and Reduce Cost

“…Technical errors in its creation lead to potential complications including: nausea, vomiting, strictures, and leaks. Linear-stapled anastomosis, hand-sewn anastomosis, and circular-stapled anastomosis are three different techniques described with good results for performing the gastrojejunal anastomosis [13,14]. We have had experience with all three techniques, but we choose to use the circular stapler for our GJ anastomosis because it offers the most consistent stoma size for our patients.…”

“…Techniques for the GJ include circular-stapled anastomosis, linear-stapled anastomosis, and hand-sewn anastomosis [13,14]. In the circular-stapled technique, the anvil of the stapler can be introduced into the gastric pouch transabdominally or pulled down the esophagus (transoral) [5,[14][15][16].…”
