• Restrictive surgeries, such as the Lap-Band® procedure, the vertical banded gastroplasty ("stomach stapling"), and the sleeve gastrectomy, physically limit the amount of food a patient can consume by reducing the size of the stomach or the amount it can expand.
• Combined procedures, including Roux-en-Y gastric bypass, do the same but also surgically reroute the digestive tract so that food actually bypasses most of the stomach. Combined procedures make up 80 to 85 percent of all bariatric surgeries performed in the United States.
• Malabsorptive procedures, or biliopancreatic diversion bypass, do not regulate intake but instead limit the absorption of calories and nutrients from food by creating a bypass around a significant length of intestine.
• Some bariatric procedures are performed with traditional "open surgery," necessitating a large abdominal incision, while others can be performed laparoscopically, meaning that they are conducted by making small incisions in the abdomen and inserting tiny instruments through those incisions.
• In some cases, bariatric surgery that may typically be performed laparoscopically is inadvisable because of a patient's weight, body shape, or previous surgeries. In those instances, open surgery can usually be performed instead.
• To determine which, if any, procedure may be appropriate, bariatric surgeons must weigh the risks versus the benefits for each patient. The patients as well as their doctors should also consider which procedures the surgeons have the most experience performing.
