Roux-en Y Divided Gastric Bypass
Named after the surgeon who first described the procedure, Cesar Roux, the Roux-en Y procedure reconfigures parts of the stomach and intestine to resemble a stick Y-shape. It reduces the capacity of the stomach to a small pouch that holds about one ounce of food. The pouch is completely divided from the stomach and is connected to the small intestine so that it can empty. Limiting the amount of food a patient can eat and the number of calories that the patient’s body can absorb helps the patient achieve dramatic weight loss while often controlling Type 2 diabetes, high blood pressure, sleep apnea, and other health problems.
Sleeve gastrectomy is a restrictive weight loss surgery that permanently removes 85% of the stomach. This procedure is helpful for patients who wish to lose weight but have health conditions that make combined restrictive/malabsorptive surgery less safe at this point in time. Your surgeon will use staples to divide your stomach into two parts. The surgeon makes one part into a narrow tube that will carry the food. The other side of the stomach is no longer used. When you eat, the food goes into the narrow tube and leaves through your intestines (the tube that takes food away from your stomach) as normal. The stomach tube can only take a few ounces of food. This means you should feel full sooner than usual.
Adjustable Gastric Band
The adjustable gastric band is the only adjustable surgical treatment for morbid obesity. It causes weight loss by reducing the capacity of the stomach, which restricts the amount of food that can be consumed. During the procedure, surgeons use small incisions to implant an inflatable silicone band into the patient’s abdomen. Like a wristwatch, the band is fastened around the upper stomach to create a new, tiny stomach pouch that limits and controls the amount of food that is eaten. It also creates a small outlet that slows the emptying process into the stomach and small intestine. As a result, patients experience an earlier sensation of fullness and are satisfied with smaller amounts of food.
