Different Gastric Bypass Surgery for Weight Loss

According to Dr. Roberto Rizzi (Franco e Rizzi) there are three major variations of gastric bypass suurgery. If you are considering gastric bypass surgery to obtain weight loss, you should be aware of the differen gastric buypass procesdures available to you.

1. Loop Gastric Bypass (later called the Mini Gastric Bypass) The first gastric bypass was in 1967, It used a loop of the small bowel for re-construction. Although simple to create, it allowed corrosive juices from the small bowel to enter the gastric pouch, sometimes causing severe inflammation and ulcers. It was was abandoned but recently re-employed by a few surgeons, as the "Mini-Gastric-Bypass", mainly to simplify the reconstruction, when performed laparoscopically. Although the mini gastric bypass has a low complication rate, there are now multiple reports in the medical literature of serious long-term complications with the procedure, even requiring revision surgery.

2. Proximal Roux-en-Y Gastric Bypass. This is by far the most commonly performed bariatric procedure in the United States. It is the operation which is least likely to result in nutritional difficulties. The small bowel is divided about 18 in below the lower stomach outlet, and is then re-arranged into a Y-configuration, to enable outflow of food from the small upper stomach pouch, via a "Roux limb". In this proximal version, the Y-intersection is formed near the upper end of the small bowel. The Roux limb is constructed with a length between 30 to 60 inches, preserving most of the small bowel for absorption of nutrients. The patient gets quickly a sense of stomach-fullness, followed by a satiety feeling, shortly after the start of a meal.

3. Distal Roux-en-Y Gastric Bypass. As the Y-connection is moved farther down the Gastro intestinal tract, the amount of the bowel capable of fully absorbing nutrients is reduced. The Y-connection is made closer to the lower end of the small bowel, usually 40 to 60 inches from the lower end of the bowel, causing reduced absorption of food, mainly fats and starches, but also various minerals, and fat-soluble vitamins. The unabsorbed fats and starches pass into the large intestine, where bacterial action produces often irritants and malodorous gases.
