Laparoscopic bariatric surgery is a minimally invasive operation that reduces the stomach capacity to a very small volume and helps a person to lose weight. The most commonly performed laparoscopic bariatric operations are the Laparoscopic Gastric Bypass and the Laparoscopic Gastric Banding operations.


The Laparoscopic Gastric Bypass operation (also called Laparoscopic Roux-en-Y Gastric Bypass) is considered the standard operation in bariatric surgery. It is performed by laparoscopic technique, through tiny holes (ports), made in the abdomen. One of the ports is for placing a laparoscope (a long slender camera), which gives excellent visualization of the inside of the abdomen. The other ports are used for passing long slender instruments to perform the operation without having to cut open the abdomen. Stapling instruments are used to construct a new tiny stomach pouch (about 15-30 ml), which is connected to the small intestine, bypassing the rest of the stomach (see details of the operation). Because it is minimally invasive, incisional pain is usually minimal.

The Laparoscopic Gastric Banding operation is also performed by laparoscopic technique. A hollow band of silicone rubber is placed around the upper part of the stomach to restrict the eating capacity. The band is connected to an injection port, which is implanted underneath the skin of the abdomen and will later be used for adjusting the size of the band and its corresponding stomach restriction in the months following the operation. It requires close follow-up intervals for band adjustment and is less effective than the gastric bypass operation for long-term weight control, but it is sometimes performed in patients who specifically request this operation.

If you are overweight to the degree that is defined as morbid obesity, you may be a candidate for Laparoscopic Bariatric Surgery.
