I joined the Department of Surgery in 2008 to create the new Bariatric and Metabolic Surgery Program which offers a range of fully laparoscopic procedures – including gastric bypass and gastric banding – to help morbidly obese individuals begin the journey to healthier lives. The focus of my prior experience at the University of Tennessee was with procedures that are entirely laparoscopic. Thus, the procedures are less invasive, so patients do better and recover more quickly.

Gastric bypass is considered the “gold standard” operation for weight loss. Performed since the 1960s, it is the most common weight-loss procedure in the United States and around the world. The bypass we perform at Jefferson only bypasses approximately one-third of the intestinal tract, leaving the last two-thirds to be the “common limb,” which absorbs food relatively normally. The amount of malabsorption caused by the bypass that we perform is minimal and easily overcome from a nutritional standpoint by taking a few over-the-counter supplements every day. By eating less and not fully absorbing calories in food, most people will lose 60–70 percent of their excess body weight with this procedure.

The support of the hospital and the Department Chair, Charles Yeo, MD, has enabled us to achieve great results in a small amount of time. Since January 2009 my bariatric surgery colleague Bernadette Profeta, MD and I have performed close to 80 procedures, which is an impressive volume for a young program.

This all contributes to being able to make a difference in the lives of patients like Josephine Lacaba. I feel extremely lucky to work in an area of medicine in which we can actually reverse chronic, lifethreatening conditions. It’s very rewarding work—the patients are genuinely grateful for our help.
