Surgical Options for Bariatric Surgery

With over 15 years of experience, UChicago Medicine leads the Midwest in all four surgical options for the treatment of severe obesity using minimally invasive techniques.

With minimally invasive surgery, patients experience less pain, less scarring and a shorter hospital stay than traditional surgeries. Read more about the procedures we offer below. 

Surgical Options

During a VSG procedure, the stomach is permanently reduced to about 15 percent of its original size, leaving a sleeve-shaped portion that can hold less food and is resistant to stretching. Depending on the individual needs of each patient, the surgery can be performed as a single, primary procedure or as the second part of a two-stage procedure to help patients lose weight before undergoing another weight loss surgery, such as duodenal switch or Roux-en-Y gastric bypass.

One of the most frequently performed weight loss surgeries in the country, RYGB is when the upper portion of the stomach is stapled and the upper intestine is connected to the stomach. Food is rerouted so it does not come into contact with the main stomach area. Stomach size is reduced to the size of a golf ball, making patients feel fuller between meals. In addition, patients may find that they no longer crave — or even like — sweet foods.

The biliopancreatic diversion with duodenal switch (BPD/DS) — commonly referred to as the duodenal switch — can help patients lose more weight than with other bariatric procedures.  In addition to reducing obesity, the BPD/DS can also resolve other related health issues, such as heart disease, high blood pressure and type 2 diabetes.

BPB/DS is a complex procedure that combines a sleeve gastrectomy with intestinal bypass. As a result, a patient feels fuller faster and the body’s ability to absorb calories, vitamins and minerals is decreased.

The BPD/DS procedure is complex and is usually recommended for patients who are severely obese, with a a body mass index of 50 or higher or 40 or higher along with other health problems. Most patients can expect to lose 60% to 80% of their excess weight.

We are also a regional and national referral center for complex and revisional bariatric surgery.

At UChicago Medicine, we are dedicated to long-term, follow-up care. When you have surgery here, we offer continued care for the rest of your life. Our patients have access to our dietitians, nurses and physicians for as long as needed.

We understand that bariatric surgery is a life-changing procedure. We offer a monthly support group for patients facilitated by a clinical psychologist with the participation of surgeons, nurses and dietitians.

Why Minimally Invasive Surgery?

At UChicago Medicine, all of our bariatric surgeries are performed laparoscopically, a minimally invasive technique that requires five or six small incisions ranging from 1/4 to 3/4 inches in length. Laparoscopic approaches offer the same potentially life-saving results as traditional "open" obesity surgeries — which require a single large incision extending from the lower edge of the breastbone down to the belly button — but with significantly less pain and fewer complications, such as wound infections and hernias. Patients typically return home two to four days after their surgery and usually return to work and other activities significantly earlier than they would after traditional weight loss surgery.

During a laparoscopic procedure, the surgeon inserts a laparoscope, which is a thin tube with a tiny video camera on the end of it, through a 10-millimeter incision in the middle of the abdomen. The surgeon then inserts surgical instruments through the additional incisions to perform the operation. Throughout the surgery, the laparoscope's camera projects a high-resolution, magnified image of the surgical field onto multiple video monitors, allowing the surgeon to perform the procedure safely and with high precision.

Patients from across the country turn to UChicago Medicine for obesity surgery. Our surgeons perform hundreds of obesity surgeries a year. With their surgical expertise and the strength of a supporting multidisciplinary team, we are able to help many patients who are often considered to be too obese or high risk for laparoscopic weight loss surgery. Our surgeons' rate of surgical complications is also lower than the national average, despite the larger and higher-risk patients treated at our center.
