Types of Bariatric Surgery

Gastric sleeve surgery, or vertical sleeve gastrectomy, is the most common option nowadays. The procedure is performed under general anesthesia. During the procedure, the surgeon narrows the stomach into a thin vertical sleeve, about the size and shape of a banana. The remainder of the stomach is removed. This is a merely restrictive operation.  The patient’s smaller stomach gets full quickly after eating smaller portions of food, so the patient is satisfied after consuming less calories. Digestion and absorption of nutrients is not impaired and the patient seldom needs any dietary supplements.

Gastric Bypass Surgery
Gastric bypass surgery is the most common bariatric – or weight loss – procedure performed. After surgery, patients are unable to eat as much as they used to prior to the procedure because the stomach is now smaller. The procedure is performed under general anesthesia.

Using staples, the surgeon divides the stomach into a small upper section and a larger bottom section. Following surgery, the top section of the stomach, called the pouch, is where food eaten goes. This pouch is about the size of a walnut. It holds only about 1 ounce of food.

The next phase during gastric bypass surgery is the bypass. The surgeon connects a small part of the small intestine, also called the jejunum, to a small hole in the pouch. Food eaten will then travel from the pouch into this new opening in the small intestine, which results in the body absorbing fewer calories.
Gastric bypass can be performed in two ways. With open surgery, the surgeon will make a large surgical cut to open up the belly in order to have access to the stomach, small intestine, and other organs.

Another option, and the more common today, is for the surgeon to use minimally invasive techniques which require making four to six small cuts in the belly. The cuts make it possible for a tiny camera called a laparoscope to be inserted into the body along with thin surgical instruments for the surgeon to divide the stomach and perform the bypass.

Weight loss surgery may require that the patient have a tube inserted into the stomach via the mouth in order to remove fluid. Patients are not permitted to eat for one to three days following surgery. Once they can eat, fluids followed by pureed food are required before they can eat and digest solid food.
