Types of Bariatric Surgery

Gastric Banding: Gastric banding, done laparoscopically, is less invasive and the only adjustable reversible obesity surgery available. During this procedure, surgeons place an inflatable silicone band around the upper stomach to create a new, smaller stomach pouch that limits the amount of food that can be consumed and slows the progression into the stomach and intestines. The patient feels full sooner and satisfied with smaller amounts of food, ultimately losing up to 40-60 percent of his of her weight over three years.

The band itself is adjustable by adding or removing fluid from the band’s interior through a small port that is placed beneath the patient’s skin. The surgeon can adjust the band via the port with minimal discomfort to the patient. If the band needs to be removed, the stomach will return to its original form and function.

 


 

Laparoscopic Gastric Bypass (Roux-en-Y Gastric Bypass): If greater weight loss is required than banding techniques can produce, a gastric bypass operation is considered. Gastric bypass procedures reduce food absorption, in addition to restricting food intake. Patients who have gastric bypass procedures generally lose 70 percent of their excess weight within 1 ½ years. In Roux-en-Y gastric bypass (RGB), the most common weight loss procedure, a small stomach pouch is created by stapling, which separates it from the rest of the stomach. Then a section of small intestine is attached to the new pouch to allow food to bypass most of the stomach and first portion of the small intestine to reduce calorie intake and nutrient absorption. The limited quantity of food, combine with reduced absorption of calories, results in a faster weight loss than is normally achieved by the banding procedure.

 


 

Laparoscopic – Sleeve Gastrectomy: In this surgery approximately 70 percent of the stomach is removed to limit the volume of food intake at one time.  This procedure  similar to the band procedure, there is restriction in the volume of food intake. One can lose around 40-60% of their excess weight over 18 months. Unlike the band operation, this operation is permanent.



 

Bilio-Pancreatic Duodenal Switch Surgery: After the stomach is divided as described above, the gastric sleeve resection is usually carried out several months later as the second stage operation.  During this surgery, the stomach and the first part of the small intestine are surgically separated and reattached to the last portion of the small intestine.. Bilio-pancreatic duodenal switch surgery is reserved for the most severely obese patients.

 


 

Revisional Endoscopic and Laparoscopic Surgery:  While, dietary modification and lifestyle go hand in hand with bariatric surgery to achieve long term success, In some instances revisional bariatric surgery is needed to remove a malfunctioning band, revise a laparoscopic Sleeve gastrectomy or gastric bypass. Both  surgical and endoscopic procedures are made available to our patients who may need revisional baratric surgery for weight regain or malfunctioning previous bariatric surgery.
