Revision Surgery for Suboptimal Weight Loss or Recurrent Weight Gain After Roux-en-Y Gastric Bypass

"1. The entire previous gastric bypass construction is released from any adhesions and all parts of the small intestine are measured and assessed.~2. All or parts of the first part of the intestine that food reaches after the gastric pouch (so-called Roux) is resected. The reason is that parts of the intestine that are considered to be of poor quality (for example, affected by a lot of adhesions or abnormally dilated) are removed. This can be about 1.5 meters of intestine, which corresponds to 10-25% of the entire length of the small intestine.~ The gastric pouch will be small (\<30 ml).~3. A new gastric bypass construction is constructed where the intestine receiving food from the esophagus (Roux) will be 1 meter, and the small intestine part from the closed stomach at least 1.5 meters.~The remaining length of the small intestine below the jejuno-jejunal anastomosis should be minimum 3 meters."
