Weight Loss Options


The most popular weight loss procedure, the Roux-en-Y Gastric Bypass (GBP), can now be performed laparoscopically. In most cases, this minimally invasive surgery only requires six small incisions.

How it Works
The stomach is divided into two parts using a surgical stapler. The upper part forms a small (approximately ½ ounce) pouch which receives food. We then create an outlet from the pouch to a portion of small bowel (150 cm Roux limb) using a circular stapler.

This results in a bypass of most of the stomach and duodenum. The average hospital stay is usually 2-3 days. Reported weight loss from the GBP can vary widely. However, it is generally reported that average excess weight loss ranges from 60% to 70% within one to two years.

Chart of Bypass ResultsHow it Differs from the LAP-BAND® System Procedure
The Roux-en-Y is restrictive and malabsorptive. It restricts intake and also lessens the absorption of food. In contrast to the gradual weight loss from LAP-BAND® System Procedure, three quarters of the weight loss occurs in the first year with Roux-en-Y.

Potential Complications
As with any surgical procedure, there are potential complications. They include gastric perforation, leakage from the anastomosis (hook-up), vitamin/mineral deficiencies, and blood clots. In addition, the average mortality rate is 1% nationally.
