The decision to have Revision Surgery is not made easily. You should know that Dr. Mehta is a highly experienced bariatric surgeon, with one of the most in-depth training in revision surgeries. He did his fellowship under tutelage of Bariatric Surgery pioneer Dr. Brolin, where he was trained in many type of revision operations including variations of older Gastric Bypasses, Long Limb Gastric Bypass, Duodenal Switch, Jejuno-ileal bypass, Fobi-pouch, Marginal ulcers...etc. This type of training is rarely found these days, and is key into having knowledge and in-depth experience, which cannot be easily substituted. He has been performing laparoscopic revision surgeries over his entire career and has treated many patients who traveled far distances for his expertise.
You should also find comfort in knowing that Dr. Mehta has modified many revision operations over the years, using minimally invasive techniques, and modifying the way they are being done in an attempt to making them simpler and safer for patients. Many of the revisions can be done without cutting the stomach or the intestines, thereby substantially decreasing the chance of a leak, and increasing patient safety.
Additionally, Dr. Mehta personally performs each and every surgery or procedure, in their entirety from beginning to end. Surgeries are NEVER handed off to an assistant surgeon, a junior partner, or a resident. Very often this is the case in teaching hospitals, or in groups with less experienced surgeons. Dr. Mehta also personally checks on each and every patient himself after the surgery, including on weekends. He also gives out his personal cell phone number to his patients so they have quick access to him should they have any questions or concerns. Spend some time reading his testimonials to see what his patients have to say.
