Kalorama Information estimates about 40% of all bariatric surgery procedures involve gastric banding. The gastric banding market is the largest general segment in the bariatric surgical market with over 90% of total surgical device sales. Other segments include intragastric balloons and suture systems. Allergan, one of the leading development companies involved in obesity surgical devices, reports 450,000 Lap-Band devices sold since 1993 throughout the world.

The most commonly performed gastric bypass procedure, Roux-en-Y Gastric Bypass (RYGB), involves a stomach pouch for food intake restriction and a direct Y-shaped connection made from the ileum or jejunum to the stomach pouch for malabsorption. The RYGB procedure has been performed regularly since the early 1980s and was first performed laparoscopically in the early 1990s. RYGB is one of the most common types of weight loss procedures in current use.
