Roux-en-Y Gastric Bypass Surgery

Roux-en-Y gastric bypass surgery (RYGB) is recognized as the gold-standard treatment for morbid obesity due to its low complication rate and long-term success in achieving and maintaining weight loss.

The procedure combines a restrictive operation with a small amount of malabsorption. The stomach is divided into two parts. The upper pouch receives food from the esophagus. The lower part receives no food, but sends stomach acid to the duodenum. The surgeon divides the small intestine in the upper jejunum and creates an anastamosis to the small stomach pouch with a dime-sized opening. The other end of the jejunum is reconnected, creating a "Y" shape. Absorption of food begins at the anastamosis of the jejunum.

Risks and Complications of RYGB

RYGB has the highest long-term success rate and low rates of mortality, complication and failure. The procedure carries a mortality rate of less than 1 percent, an operative complication rate of less than 5 percent, and an effective loss of 50 to 75 percent of excess weight.
