Background: The placement of a ring circumferentially around the gastric pouch of a vertical gastric bypass has the advantage of permanently fixing the size of the gastric outlet and slowing the passage of food into the jejunum. Opinion remains divided about the use of rings, and the optimal size.
Methods: Since 1990, we have consistently placed a ring at the time of gastric bypass surgery and have an experience with three ring sizes (circumference); 5.
Background: While a great deal has been published regarding the short- and medium-term outcomes of gastric bypass surgery, much less information is available regarding long-term follow-up. Such information would be valuable in changing attitudes towards this surgery.
Methods: 342 severely obese patients underwent gastric bypass between June 1990 and April 2003 by a single surgeon.
