Mayo Clinic surgeons perform the following types of bariatric surgery procedures.
Most are done using minimally invasive (laparoscopic) surgery, which can help decrease hospital stay time and speed up your recovery.
Roux-en-Y gastric bypass reduces stomach size and is the most common procedure performed at Mayo Clinic.
The very, very long limb gastric bypass is a modified version of the Roux procedure. Developed by a Mayo surgeon, it is preferred for severely obese people (usually men who weigh more than 400 pounds and women over 350 pounds). This procedure differs from the standard Roux-en-Y in that the bypassed segment of intestine containing the digestive juices is attached to the food-carrying intestine closer to the large intestine. This further restricts nutrient and calorie absorption.
Biliopancreatic diversion with duodenal switch is similar in some ways to Roux-en-Y gastric bypass, but keeps some stomach function intact while bypassing most of the intestine.
Laparoscopic gastric banding involves placing an inflatable band around the upper portion of the stomach to restrict the amount of food you can consume. This minimally invasive procedure is adjustable and reversible.
Sleeve gastrectomy involves surgically removing the left side of the stomach, leaving a much smaller stomach about the size and shape of a banana.
