Our group has experience with over 6000 of these procedures, and we have striven to refine our techniques and methods to produce the maximum sustained weight loss achievable. The small intestine is cut about 18 inches below the stomach, and is re-arranged so as to provide an outlet to the small stomach, while maintaining the flow of digestive juices at the same time. The lower part of the stomach is bypassed, and food enters the second part of the small bowel within about 10 minutes of beginning the meal. There is very little interference with normal absorption of food - the operation works by reducing food intake, and reducing the feeling of hunger. The result is a very early sense of fullness, followed by a very profound sense of satisfaction.
Patients continue to enjoy eating - but they enjoy eating a lot less.
The Gastric Bypass provides an excellent tool for gaining long-term control of weight, without the hunger or craving usually associated with small portions, or with dieting. This operation duplicates the anatomy and physiology of the standard, open procedure. The benefits of the laparoscopic approach come from the very small incisions which are necessary, which cause much less pain, and very little scarring. Patients are able to get up and walk within hours after surgery, can breath easier, and move without discomfort. Bowel activity usually is not affected, as it is with an open incision.
