What is Bariatric Surgery?
Pathway to Surgery
Our team of experts has years of experience in the following procedures:
Roux-en-Y
The most common gastric bypass surgery performed in the U.S. First, a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits how much food you can eat. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of the jejunum. This causes reduced calorie and nutrient absorption. This procedure can now be done with a laparoscope (a thin telescope-like instrument for viewing inside the abdomen) in some people. This involves using small incisions and generally has a more rapid recovery time.
Laparoscopic Gastric Bypass
Performed by introducing a laparoscope through small abdominal incisions. The entire operation is performed "inside" the abdomen. Special stapling instruments are used to create a new small stomach pouch. The remainder of the stomach is not removed (99%), but is completely stapled shut and divided from the new small stomach pouch. Provides faster recovery.
Laparoscopic Banding
Adjustable gastric banding limits food intake by placing a constricting ring completely around the stomach below the junction of the stomach and esophagus. The small gastric pouch (the size of a golf ball) restricts the amount of food that can be consumed at a meal. Ingested food consumed passes through the digestive tract in the usual order, allowing it to be fully absorbed into the body.
This type of restrictive weight loss occurs with the reduction of the size of the stomach, to about 60 cc in volume. As a result, patients feel full after a very small amount of food, and therefore lose weight because they eat less. There are also significant effects on the hunger mechanisms that make the weight loss seen with the sleeve gastectomy even better than would be seen just with a small stomach pouch. Hunger is favorably affected because there is a reduced capacity to produce Ghrelin, a substance that plays a role in how you feel and relieve hunger. Weight loss with the sleeve gastrectomy ranges from 55% to 70% of excess body weight, depending on your circumstances.
