Laparoscopic Revision of Open Roux-En-Y Gastric Bypass with Fundus Resection: This video presents a 37-year-old female with a BMI of 57. In 1994, she underwent open gastric bypass surgery but never achieved the desired weight loss. Esophagogastro-duodenoscopy showed a large pouch. The patient was taken to the OR for laparoscopic revision of the bypass. The stomach was mobilized, and by using green load EndoGIA, the stomach was divided just below and above the previous staple lines. Fundus was then divided and resected. The jejunum was divided from the gastrojejunostomy by using a blue load EndoGIA. The gastrojejunostomy was reconstructed in 2 layers over a 34F bougie. On POD 1, UGS showed a functional small pouch without evidence of leakage. At 6-month follow-up, the patient had lost 81 pounds. Laparoscopic revision of open Roux-En-Y gastric bypass surgery is safe and feasible, even in patients who have had a previous open weight loss procedure.
