Sleeve Gastrectomy


Being overweight or obese can increase your risk of serious medical conditions, including heart disease, cancer, diabetes, metabolic syndrome and more. Sleeve gastrectomy is a surgical procedure that can help treat those who have weight-related disease. At The University of Kansas Health System, we offer sleeve gastrectomy to help you lose weight and reach your health goals.

Although dramatic weight-loss is one of the benefits of sleeve gastrectomy, the procedure also significantly improves health by reducing the effects of medical conditions associated with being obese or overweight.

To schedule an appointment, call 913-588-1227, or request your appointment online. The University of Kansas Health System provides sleeve gastrectomy surgery for people in Kansas City, Overland Park and throughout the region.

What is sleeve gastrectomy?

Sleeve gastrectomy was first performed in 1988 as a part of the more invasive duodenal switch procedure. The sleeve is the portion of the operation that permanently changes the size of the stomach to about 15% of its original size. The remaining stomach is a small, tubular pouch that holds considerably less food.

Sleeve gastrectomy also affects hormones in the gut that can help you feel less hungry. These hormones impact blood sugar, often improving weight-related conditions like type 2 diabetes. Sleeve gastrectomy results seem to be as effective as Roux-en-Y gastric bypass for weight loss and remission of diabetes, based on short-term studies.

Sleeve gastrectomy pros and cons


  • No intestinal re-routing
  • Less complex than gastric bypass
  • No implanted device


  • Limited long-term studies
  • Not reversible
  • Slower, less significant weight loss

Benefits of sleeve gastrectomy

Sleeve gastrectomy can usually be performed using minimally invasive techniques. Because the surgery does not include intestinal bypass, there are fewer long-term complications such as malnutrition, ulcers and intestinal obstructions.

Studies also show the return of cravings is reduced with this procedure when compared with the adjustable gastric band. Patients who have sleeve gastrectomy also experience greater weight loss than gastric band patients. Short-term results show that most people who have the sleeve procedure achieve a 60%-70% excess weight loss at 2 years. Long-term results are not yet available.

What to expect

Once you have fulfilled insurance requirements, been approved and consulted with your surgeon, you are ready to schedule your surgery. The office staff will work to schedule your surgery within the next few weeks.

You will see the surgeon 10-14 days before surgery. During this time, you will have a final checkup, be able to ask questions and make sure you understand your instructions for your preoperative diet and what medications to continue or stop prior to surgery. You will also have an appointment with the presurgical clinic nurse. This will prepare your medical record for the day of surgery, verify the results of any lab work and ensure that any specialty consults (cardiology,etc.) are included in your record. Additionally, staff will inform you on what to expect the day of surgery so you will feel more comfortable each step of the way.

The nurse will tell you what to bring to the hospital and what to leave at home. The nurse will also review your medications to make sure you know what to discontinue and when, and what medications you should take the day of surgery. Make a list of all prescription medications, over-the-counter medications, and any herbal or vitamin supplements you are using, and bring the list with you to the hospital.

Most people who have this surgery spend one night in the hospital and go home the next day. You may have to stay at the hospital for a few days after the procedure. Your diet after the surgery will start with clear liquids. You will then transition to soft foods until your body can adjust to solid foods again. You will feel full very quickly after eating a small amount of food.

Sleeve gastrectomy may lead to a weight loss of more than 50% over 3-5 years, but the weight loss process is usually slower when compared with gastric bypass surgery. Sleeve gastrectomy is more successful when it is a part of a long-term healthy lifestyle plan that includes exercise and a diet recommended by your physician and healthcare team.

Risks and complications

Sleeve gastrectomy is a nonreversible procedure. A small percentage of people may experience complications after the surgery. Some of these complications may be serious while others are minor. Talk to your physician about the benefits and risks associated with sleeve gastrectomy.
