UW Health Medical and Surgical Weight Management surgeons perform the Roux-en-Y gastric bypass, laparoscopic adjustable gastric band and sleeve gastrectomy procedures as well as revisional surgery for people who have had previous weight loss surgery.

The majority of these procedures are performed laparoscopically, where a small video camera and surgical instruments are inserted through tiny holes in the abdomen, allowing the surgeon to perform and view the surgery on a video monitor. This approach reduces operating time, leads to quicker recovery with fewer complications and reduces your hospital stay.

• Roux-en-Y Gastric Bypass: During the operation, surgical staples are used to create a small pouch at the top of the stomach. A segment of the small intestine is then attached to this pouch. Food bypasses most of the stomach and the first part of the small intestine. Read more about Roux-en-Y Gastric Bypass 
   
• Laparoscopic Adjustable Gastric Band: The laparoscopic adjustable gastric band is a device designed to limit the capacity of your stomach. This device is placed around the upper part of the stomach, forming a small gastric pouch to limit the amount of food that you eat and to slow the emptying process from the stomach into the intestines. Read more about the laparoscopic adjustable gastric band
   
• Sleeve Gastrectomy: In this procedure a large portion of the stomach is removed, leaving a narrow, tube-shaped pouch. The capacity of the new stomach pouch is three to four ounces. The sleeve is also primarily a restrictive procedure, meaning patients lose weight by limiting the amount of food they take in. There is no re-routing of the intestines and no change in the ability to absorb calories and nutrients. Watch video re-creation of surgery

• Revisional Surgery: This procedure is for patients who have already had a procedure in the past and now need some sort of revision or repair.
