Sleeve Gastrectomy Surgery
UW Health's Medical and Surgical Weight Management surgery team performs sleeve gastrectomy surgery for patients interested in bariatric surgery as way to lose weight safely.
About Sleeve Gastrectomy
- The sleeve gastrectomy procedure may be done through an open approach (large incision) or via the more common laparoscopic approach.
- A large portion of the stomach is removed, leaving a narrow tube-shaped pouch with a capacity of approximately three to four ounces.
- Unlike the Roux-en-Y gastric bypass procedure, there is no bypassing of the intestines.
- Most patients typically have a one- to two-night hospital stay.
Benefits of Sleeve Gastrectomy
- The sleeve is primarily a restrictive procedure, meaning patients lose weight by limiting the amount of food that can be eaten at a time, with some change in the ability to absorb calories and nutrients.
- The sleeve may lead to hormonal changes that decrease hunger, and have metabolic effects that may speed the resolution of diabetes.
- The sleeve gastrectomy procedure provides moderate weight loss (four to five pounds per week in the first six to 12 months).
