  1. How safe is bariatric surgery?

  2. Bariatric surgery is the branch of surgery that encompasses surgeries performed for weight loss in patients suffering with clinically severe obesity. There are various types of bariatric procedures. Some of the most commonly performed bariatric procedures are listed and described as under:

  3. Laparoscopic Sleeve Gastrectomy: Laparoscopic sleeve gastrectomy is one of the commonest bariatric procedures performed across the world. In this procedure, a long and narrow tube of the stomach is created over a calibration tube. Almost two-thirds of the outer half of the stomach is removed. This procedure leads to restriction of food intake, early satiety, decreased hunger and increased gastric emptying. It leads to a weight loss of about 65 to 75% excess weight over a period of 18 to 24 months and significant improvement in obesity associated co-morbidities. 2. Laparoscopic Roux-en Y Gastric Bypass: Laparoscopic Roux-en Y Gastric Bypass is one of the oldest and time tested bariatric procedures. It is also known as the gold standard bariatric procedure. In this procedure a 30 to 50 cc pouch of stomach is created and the small intestine is re-routed to join the stomach pouch. Most of the stomach, duodenum and first part of jejunum is bypassed. The food enters the stomach pouch and then directly into the attached jejunum. This surgery leads to restriction of food intake, early satiety, decreased hunger, some degree of mal-absorption, early release of gastro-intestinal hormones like PYY and GLP-1 and bile acid alterations. It leads to a weight loss of about 70 to 80% over 18 to 24 months and significant improvement in obesity associated co-morbidities.

  4. Laparoscopic Single Anastomosis Gastric Bypass or Mini Gastric Bypass: Laparoscopic Single Anastomosis Gastric Bypass or Mini Gastric Bypass is a bariatric procedure in which a long and narrow pouch of the stomach is created and a loop of the small intestine is joined to this pouch. Most of the stomach, duodenum and 150 to 200 cm of jejunum is bypassed. The food enters the stomach pouch and then directly into the attached jejunum. This surgery leads to restriction of food intake, early satiety, decreased hunger, early release of gastro-intestinal hormones like PYY and GLP-1 and bile acid alterations. This procedure is more mal-absorptive than a routine Roux-en y gastric bypass. It leads to a weight loss of about 70 to 80% over 18 to 24 months and significant improvement in obesity associated co-morbidities. 4. Laparoscopic Duodenal Switch: Laparoscopic Duodenal Switch is a surgery where a sleeve gastrectomy is created and most of the small intestine is bypassed. The food enters the sleeve of stomach and then directly into the attached ileum. This surgery leads to restriction of food intake, early satiety, decreased hunger, early release of gastro-intestinal hormones like PYY and GLP-1 and bile acid alterations. This procedure is extremely mal-absorptive. It leads to a weight loss of about 80 to 85 % over 18 to 24 months and significant improvement in obesity associated co-morbidities.

  5. 5. Laparoscopic Adjustable Gastric Banding Laparoscopic Adjustable Gastric Banding is a surgery in which a silicon band is placed in the upper part of the stomach, dividing it into a smaller upper pouch and a larger lower pouch.  This procedure mainly works on the principle of restriction. The weight loss achieved after this procedure was less satisfactory and gradually this procedure went out of favour. It is one of the least performed bariatric procedures. 6. Intra-Gastric Balloon Insertion: This is a non-surgical endoscopic procedure in which a silicon balloon is inserted in the stomach and inflated with fluid. This restricts the food intake. The balloon can be kept inside for 6 months to a year depending on the type of balloon. After that it needs to be removed. It leads to a weight loss of approximately 6 to 10% of the total body weight. 7. Other procedures: There are many other bariatric procedures which are relatively less popular but are recommended on an individual case to case basis. The other procedures include SADI-S, Ileal transposition, SGIT, Diverted SGIT, Loop Bi-partition etc. Note: Please remember that bariatric surgery is partnership between the bariatric team and the patient. Regular follow up is extremely important for good results. Overall complication rate of bariatric surgery is 1 to 2% and each procedure has a different set of complications which will be explained in detail to you when you come in for a consultation. All procedures require post-operative nutritional supplementation and this usually is adjusted as per your clinical reports.
