Weightloss surgeries are very commonly performed on obese or over weight persons who have unsuccessfully tried all measures to reduce their weight. These weightloss surgeries can be performed laparoscopically with various advantages as compared to open procedure. The major Laparoscopic weight loss procedures are the following:
Laparoscopic Gastric Sleeve
It is a restrictive procedure only where there is no bypass of the small intestines. The procedure involves removal of about 60 percent of the stomach so that it takes the shape of a tube or sleeve.
Laparoscopic Adjustable Gastric Banding
It is a restrictive procedure in which the small intestine is not altered. A gastric band is an adjustable silicone ring that is placed around the stomach 1-2 cm centimetres below the esophagus. This ring is attached to tubing, which is threaded under the skin to a round "port".
Laparoscopic Roux-en-Y Gastric Bypass (RNY)
This is both a restrictive and malabsorptive procedure in which the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples. This newly created smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum). This allows lesser intake of food and reduces calorie absorption.
Laparoscopic Biliopancreatic Diversion with Duodenal Switch
It is both a restrictive and malabsorptive procedure and is usually reserved for those patients with a BMI over 55. The procedureinvolves reducing the size of the stomach by dividing the stomach vertically and removing more than 85 percent of it leaving behind a banana shaped stomach. This is followed by biliopancreatic diversion with duodenal switch in which a larger portion of the stomach is kept intact to regulate the release of stomach contents into the small intestine. The DS procedure keeps the pyloric valve intact.
