Laparoscopic approach to open gastric bypass

Background: Gastric bypass is a successful tool in the treatment of morbid obesity. In recent years, laparoscopic Roux-en-Y gastric bypass has gained popularity. However, open bypass is sometimes more suitable for patients who are “superobese.” Laparoscopic instrumentation can be used during an open gastric bypass to facilitate dissection, formation of the gastric pouch, and creation of the gastrojejunostomy. Methods: We describe the use of laparoscopic ultrasonic coagulating shears for dissection during open gastric bypass. Additionally, laparoscopic gastrointestinal anastomosis and end-to-end anastomosis staplers are used for creating bowel anastomoses. Conclusions: Laparoscopic instrumentation can be useful in the setting of open procedures. Their long handles and jaw design make them ideal for working in the depths of a superobese abdomen
