a surgical procedure that combines the creation of small stomach pouches to restrict food intake and the construction of bypasses of the duodenum to prevent food absorption
A weight-loss procedure performed by bariatric or general surgeons that utilizes stapling, suturing and other surgical techniques to create a very small stomach pouch, severely restricting the amount of food that can be consumed at one time. The rest of the stomach is bypassed and therefore no longer receives food.
Operation designed to make non-functional a portion of the stomach
A type of operation that combines the creation of a small stomach pouch to restrict food intake and the construction of bypasses of the duodenum and other segments of the small intestine to cause malabsorption (decreased absorption of nutrients).
Anti-Obesity Operation Which Bypasses The Intestine And Makes A Small Stomach
A surgical procedure for the treatment of obesity where a thumb-sized stomach pouch is created using stapling techniques to divide the stomach and then connect the outlet of the pouch directly to the intestine (also known as the bowel), essentially "bypassing" the lower stomach. The flow of digestive juices is preserved, however. This procedure achieves its effect by restricting the volume of food consumed and also the type of food consumed. Sugars and fats may cause discomfort known as the "dumping syndrome." Gastric bypass surgery can be performed via open surgery (one large incision) or less invasively with laparoscopic techniques (several tiny incisions), although laparoscopic gastric bypass is performed infrequently. Produces rapid and significant weight loss but is associated with higher mortality and complication rates. Also known as Roux-en-Y or RYGB.
