Vertical banded gastroplasty, or VBG, is an elective surgical procedure in which the stomach is partitioned with staples and fitted with a plastic band to limit the amount of food that the stomach can hold at one time. Gastroplasty is a term that comes...
from two Greek words, gaster or "stomach," and plassein, "to form or shape.""Stomach stapling," also known as VBG, is part of a relatively new surgical subspecialty called bariatric surgery. The word "bariatric" is also derived from two Greek words, barys, which means "heavy," and iatros, which means "healer." A restrictive bariatric procedure, VBG controls the amount of food that the stomach can holdâ€”in contrast to malabsorptive surgeries, in which the food is rerouted within the digestive tract to prevent complete absorption of the nutrients in the food.
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.
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.
Average excess weight loss at five years is 48-74 percent after gastric bypass and 50-60 percent after vertical banded gastroplasty -2004
