Background:
Laparoscopic Roux-en-Y gastric bypass is being undertaken with increasing frequency. We describe a technique for introducing the anvil of the circular stapler using a totally transabdominal approach.
Methods:
One hundred consecutive patients underwent laparoscopic Roux-en-Y gastric bypass in a university-affiliated teaching hospital.
Results:
The cardiojejunostomy was constructed in all 100 patients using the circular stapler with no complications. No anastomotic leaks were detected postoperatively.
Conclusions:
The totally transabdominal approach for introducing the anvil of the circular stapler into the gastric pouch is safe and feasible.
