The Roux-en-Y gastric bypass procedure reduces the size of the stomach and reroutes food through the intestine. It involves dividing the upper portion of the stomach to create a smaller stomach pouch. This restricts the amount of food that can be consumed at one time. The surgeon then connects the pouch to a section of the lower intestine, so that the food will bypass the area where calories and nutrients are absorbed.

The Roux-en-Y gastric bypass surgery also causes changes in hormones that can help to promote a feeling of fullness.

Whenever possible, our surgeons use a minimally invasive laparoscopic approach, which often requires a shorter hospital stay. Minimally invasive surgery may lead to less pain and scarring and a quicker recovery.

In an adjustable gastric banding procedure, also called "lap band," an inflatable silicone band is placed around the uppermost part of the stomach, dividing it into two parts: a small upper pouch and a lower stomach. With a smaller stomach pouch, patients begin to feel fuller sooner because their hunger is satisfied by a smaller amount of food. As a result, they are able to decrease the total amount of calories consumed.

The band can be adjusted - tightened or loosened - as needed during follow-up visits. This procedure is reversible and less invasive than most weight-loss surgeries.

Although individual results may vary, most patients who undergo this procedure can lose up to half of their excess weight. And as with other weight-loss procedures, adjustable gastric banding can result in additional benefits, such as lower cholesterol and blood pressure, less joint pain, more energy and better sleep. It can also reduce the risk of other weight-related health problems, such as Type 2 diabetes, heart disease, stroke and certain types of cancer.

Biliopancreatic diversion with duodenal switch involves two primary steps. First, a sleeve gastrectomy is performed, removing the majority of the stomach, creating a small banana-shaped sleeve or smaller stomach. This restricts the amount of food you can eat in one setting and helps you feel fuller faster. Next, the upper portion of the small intestine, called the duodenum, is bypassed, and reattached near the lower end of the small intestine, decreasing the body's ability to absorb calories.

This surgery produces favorable changes in gut hormones to reduce appetite and improve satiety (the feeling of being full). It also can be effective at improving or resolving Type 2 diabetes, lowering blood pressure and cholesterol, reducing joint pain, and improving other obesity-related health conditions. It can help reduce the risk of other health problems, such as heart disease, stroke, depression and certain types of cancer.

An intragastric balloon is a non-surgical option for qualified patients. This procedure is typically used to help individuals starting a diet-and-exercise regimen who want assistance controlling their hunger and limiting their food intake. It can also help patients lose weight before surgery to reduce their risk of complications.

The intragastric balloon is a soft, expandable silicone balloon inserted during an outpatient visit. After a patient is mildly sedated, a deflated balloon is inserted through the mouth and down the esophagus into the stomach. Once in place, the balloon is slowly inflated with saline through a tube. This creates a sense of fullness and restricts the amount of food you can eat at one time.

The balloon is a short-term solution and can be left in place for six months. Patients who combine a medically supervised diet and exercise program with the balloon tend to experience and maintain more weight loss.

The single anastomosis duodenal switch, also called a "loop duodenal switch," starts with a sleeve gastrectomy, removing a large portion of the stomach to create a smaller, banana-shaped pouch that holds less food. This restricts how much you can eat at one time and helps you feel full faster.

A lower section of the small intestines is then looped and reconnected to the stomach through one new connection. This allows food to bypass much of the small intestine, decreasing calorie absorption. Unlike the biliopancreatic diversion with duodenal switch, this surgery, as its name suggests, requires only one new connection to the small intestine.

As with other bariatric surgeries, SADI-S can aid in the improvement or reversal of Type 2 diabetes, hypertension, high cholesterol, joint pain, sleep apnea and other obesity-related health conditions. It can help reduce the risk of heart disease, stroke, depression, and certain types of cancer.
