WEIGHT LOSS SURGERY- GASTRIC BYPASS
Procedures that alter digestion are known as malabsorptive procedures. Malabsorptive techniques reduce the length of intestine that comes in contact with food so that the body absorbs fewer calories. According to the American Society for Bariatric Surgery and the National Institutes of Health, Roux-en-Y gastric bypass is the current gold standard procedure for weight loss surgery. In this procedure, stapling creates a small (15 to 20cc) stomach pouch. The remainder of the stomach is completely stapled shut and divided from the stomach pouch. It is not completely removed. The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, called the Roux limb, thus eliminating the duodenum and a small portion of the jejunum from the absorptive circuit. The omitted segment is connected into the side of the Roux limb of the intestine creating the "Y" shape that gives the technique its name. The length of either segment of the intestine can be adjusted to produce lower or higher levels of malabsorption.
