The laparoscopic Roux-en-Y gastric bypass is commonly referred to as “gastric bypass.” This procedure involves the creation of a small gastric pouch (roughly the size of a golf ball) from the top part of the patient’s existing stomach. The patient’s small intestine is divided and is connected to the gastric pouch (the “Roux” limb). The beginning of the small intestine (the “biliopancreatic limb”) is then connected further down the small intestine.

What is the Recovery Time?

The hospital stay for the gastric bypass procedure is typically 2 days. Recovery period for the bypass is slightly more than with the adjustable gastric banding procedure as it is more invasive. Many patients who have sedentary jobs often return to work within 2-4 weeks. Patients with jobs that require more physical effort may be out of work for 4-6 weeks.

What are the Pros/Cons of Gastric Bypass vs. Adjustable Banding?

Even though both procedures are both restrictive procedures and performed with laparoscopic techniques, There are significant differences. Each has its own distinct advantages and disadvantages:

Gastric bypass involves rearranging the gastrointestinal anatomy using surgical staplers. (A small stomach pouch is created). The surgery lasts around two hours and usually requires two nights in the hospital. The weight loss after surgery occurs over one to two years. Because most of the stomach and part of the small intestine is bypassed, patients are at risk for anemia and osteoporosis and must take vitamins and supplements for the rest of their lives. Because the stomach and small intestine is stapled and divided, there is a risk for leaking and bleeding at the staple lines.

Banding involves placing a silicone device, the Lap Band® system, around the top of the stomach. The device is connected by tubing to a port that is placed under the skin. There is no rearrangement of the anatomy. The surgery lasts around one hour and usually requires one night in the hospital, although some patients can go home the same day as surgery. The weight loss after Banding occurs over two to three years. By using a special needle to access the port, the Lap Band® can be adjusted by adding or removing saline solution. The adjustment changes the opening in the stomach at the level of the Lap Band® and, therefore, controls how much food can be eaten. Banding requires more frequent follow-up visits, where adjustments may be performed.

In summary, both Bypass and Banding can provide good, sustained weight loss; however, you must adhere to a proper diet and exercise program in order to get the best results. Bypass results in faster weight loss, but there are more risks with the surgery itself. Banding is a less-invasive surgery, but it does require several adjustments to be performed after surgery.
