A Board Certified Plastic Surgeon would be the most qualified person to do your liposuction (Smart lipo or traditional). Unfortunately, because of decreasing insurance reimbursements for surgeries like ones on your gall blader and appendix, General Surgeons have taken to doing liposuction, often using Smart lipo. These doctors have no training in plastic surgery but because the procedure is deceptively easy to do, they believe they can do it safely. I have personally seen patients who have had Smart lipo done by geneal surgeons who were destroyed by their results and were uncorrectable. So, be ware of the training each doctor claims to have and do your thorough research!
