Lap-Band,® Gastric Bypass Surgery and Sleeve Gastrectomy
In the United States, these operations are the three most common. Gastric bypass is currently the most common and has been in use since 1967. The which is the brand name for a laparoscopic adjustable gastric band (LAGB), has been in use in the United States since 2001, and has been used for longer in Europe and Australia. Gastric bypass is also called Roux-en-Y gastric bypass. When performed laparoscopically, it is often called "Lap-RNY" for short.
Sleeve Gastrectomy is a newer procedure that is rapidly gaining in popularity due to being simpler than a gastric bypass but having having similar weight loss results in preliminary studies.
All three surgical procedures designed to help a person lose weight and improve the obesity related health problems. How each surgery accomplishes this is different, and will be discussed in more detail in the sections below.
