Combined Laparoscopic Revision of the Gastric Pouch and Distalization of the Roux Limb After Failure of Weight Loss Following Roux-en-Y Gastric Bypass

Abstract

After failed Roux-en-Y gastric bypass (RYGB), the choice of a secondary procedure falls into many pathways: revision of the gastric pouch, distalization of the bypass (DRYGB), addition of an adjustable gastric band, and conversion to a duodenal switch (BPD/DS). We present the case of a 54-year-old man with initial BMI of 51.5kg/m2, who first underwent laparoscopic sleeve gastrectomy (SG) in 2010. In 2012, he underwent a RYGB procedure, and in 2015, a pouch resizing for weight regain. In 2018, he reached a BMI of 41.2kg/m2. A 3D volumetric CT scan measured a gastric pouch volume of 220cm3 and a gastrojejunal anastomosis diameter of 20mm. As shown in the video, the patient underwent a combined revision of the gastric pouch and the gastrojejunal anastomosis associated to the distalization of the Roux limb. The gastrojejunal anastomosis is identified, and vertical division of the stomach is performed along a 36 French bougie, in order to create a 30cm3 gastric pouch. Then, the jejunojejunal anastomosis is identified, and the Roux limb at the jejunojejunostomy is divided and transposed distally 100cm to create a total alimentary length of 250cm. The postoperative course was uneventful. At 1year, his BMI was 31.2kg/m2. No nutritional deficiencies were noted. Combined laparoscopic pouch resizing and distalization are safe and can lead to adequate weight loss. This technique allows the combination of an added restriction and malabsorption to the previous RYGB and could lead to an improved weight loss.
