The gastric bypass operation is the most common bariatric procedure performed in the United States and for good reason. It is extremely safe with only a 1-2% serious complication rate. It is also the most effective choice of the three with data that spans 25 years demonstrating good long term results.

This surgery is almost always performed laparoscopically, meaning through small incisions in the skin, rather than a large cut. The Roux-en-Y Procedure takes around two hours to complete. The stomach is stapled into 2 pieces, one small pouch (A) and one large remnant (B). The pouch (A) is 5% of the size of the old stomach, therefore holds much less food. The larger portion (B) of the stomach stays in place however will lie dormant for the remainder of the patient’s life.

The Roux limb carries food to the intestines. The Y limb carries digestive juices from the pancreas, gall bladder, liver and duodenum to the intestines. The food and the digestive juices mix where the Roux limb and Y limb (D) meet. The separation of the ingested food from the enzymes prevents its absorption in the bypassed segment of intestine.
