No one can guarantee you that you will not have a complication, no surgeon can. What is important to know is whether or not your doctor has the experience to deal with anything that might arise. Dr. Kelly has exclusively performed bariatric surgery for the past 10 years and it is safe to say that he has seen and done it all. He has perfected his surgery technique so as to minimize the chance for any complication to arise. His complication rate is very low, less than 1 out of 200.
