Gastric Bypass

Gastric Bypass in Greenwich Hospital

The Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is considered to be the “gold standard” procedure by the American Society of Bariatric Surgeons (ASBS). This operation is the one most commonly performed and has a proven record of significant weight loss. It includes decreasing the size of the stomach and partially bypassing the small intestine to limit the amount of calorie intake. There are many different techniques that can be used for the LRYGB, all of which are acceptable. With Dr. Neil Floch the procedure is done laparoscopically with 5 to 7 small incisions. A camera called a laparoscope, and long surgical instruments are used while the belly is inflated with carbon dioxide gas. The surgeon then operates while visualizing the internal organs on a high definition television screen. During the LRYGB, a 30-60cc pouch is created by stapling-off the stomach.

The remaining stomach stays alive and intact, and the far end is attached to the small bowel. This “remnant stomach” receives blood and produces digestive stomach acid. A 50cm section of small bowel is then measured, cut, and reattached to the stomach by stapling hand stitching, or a combination of the two. Another 50cm of the small bowel is then attached to the side of the limb to drain the new, small stomach pouch. Food is not absorbed completely because the food and digestive juices are separated for 33% of the length of the bowel. This results in weight loss.

Weight loss from this procedure averages 60-80% loss of excess body weight. The LRYGB is highly effective because patients not only eat less and feel full quickly, but they also do not fully absorb the food they eat. Doing the procedure laparoscopically results in a decreased morbidity and shorter hospital stay when compared to the open procedure. Most patients are discharged home in 2-4 days. An average of 60% to 80% of excess body weight loss can be expected within the first twenty months following this procedure. Most of the loss will occur within the first six months following the surgery. This weight loss can be maintained with post-operative lifestyle changes including diet and exercise.
