Overview of Surgeries

Adjustable Gastric Banding

Gastric banding is a restrictive surgical procedure. During this procedure, two medical devices are implanted in the patient: a silicone band and an injection port. The silicone band is placed around the upper part of the stomach and molds the stomach into two connected chambers. The injection port is attached to the abdominal wall, underneath the skin. The port is connected to the band with soft, thin tubing.

Gastric Bypass

Roux-en-Y gastric bypass surgery uses a combination of restriction and malabsorption. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a large portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food; bypassing a portion of the small intestine means the patient’s body absorbs fewer calories.

Sleeve Gastrectomy

Sleeve gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon creates a small, sleeve-shaped stomach. It is larger than the stomach pouch created during Roux-en-Y bypass—and is about the size of a banana. Sleeve gastrectomy is typically considered as a treatment option for bariatric surgery patients with a higher BMI.

ROSE Procedure (NEW)

New surgical tools now allow surgeons to reduce the size of the pouch and stoma through the patient’s mouth without making external cuts into the body. Your doctor may refer to this as the “ROSE” procedure, which stands for Restorative Obesity Surgery, Endoscopic.

Before the ROSE incisionless procedure, patients who regained weight after gastric bypass generally had few treatment options. Scarring and adhesions related to the initial bypass procedure make open or laparoscopic revision surgery very challenging. Revision surgery procedure time is typically longer than the original bypass procedure and patients can be up to three times more likely to develop a complication following revision surgery. Therefore, most patients who regain weight after gastric bypass opt not to undergo open or laparoscopic surgical revision after weighing the risks and benefits.

POSE Procedure (NEW • UNDER CLINICAL TRIAL)

The POSE procedure is an investigational, minimally-invasive weight-loss procedure that does not involve any skin incisions or scars. The procedure is designed to reduce the stomach’s ability to accommodate and stretch during meals, so you can feel full and satisfied with smaller portions.
