Like other procedures in bariatric surgery, VBG is performed only on patients who are severely or morbidly obese by NIH standards. Severe obesity is presently defined as a body mass index (BMI) of 35 or higher. Nonetheless, it is the epidemic with the greatest prevalence in the United States as of 2003. One out of every 20 adults, or 15 million people, have a BMI greater than 35.
At present, few figures are available regarding the number of VBGs performed in the United States each year compared with other types of obesity surgery. The International Bariatric Surgery Registry (IBSR) at the University of Iowa is presently compiling a database to monitor the outcomes of different procedures and to analyze statistical data about patients undergoing obesity surgery. In 2000, the IBSR analyzed data on a group of 14,641 people who had had obesity surgery as of 1998. The patients weighed an average of 280 lb (127 kg) at the time of surgery and had an average BMI of 46. Slightly less than 20% of the patients had BMIs between 35 and 39.9; 76.1% had BMIs of 40 or higher.

The animation describes gastric bypass surgery, gastric band surgery, and sleeve gastrectomy. As explained in the video, these procedures use either restrictive or malabsorptive approaches to weight loss, or both.
Other Information
Vertical banded gastroplasty (VBG), also known as stomach stapling, is a restrictive operation for weight control. Both a band and staples are used to create a small stomach pouch. In the bottom of the pouch is an approximately one-centimeter hole through which the pouch contents can flow into the remainder of the stomach and thence onto the remainder of the gastrointestinal tract.
Stomach stapling is a restrictive technique for managing obesity. The pouch limits the amount of food a patient can eat at one time and slows passage of the food. Stomach stapling is more effective when combined with a malabsorptive technique, in which part of the digestive tract is bypassed, reducing the absorption of calories and nutrients. Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine, bypassing the lower stomach, the duodenum, and the first portion of the jejunum.
This type of weight loss surgery is losing favor as more doctors begin using the adjustable gastric band. The newer adjustable band does not require cutting into the stomach and does not use any staple lines, thus making it a much safer alternative.
VBG is known in the medical community as a very serious and dangerous procedure. It has been classified by the AMA as a "severely dangerous" operation.

Because surgeons are not required to register with any medical agency, there is no precise number. However, the American Society for Bariatric Surgery reports current 2006 membership at 1500.
