Michigan Medicine bariatric surgeons are specialized in minimally-invasive techniques (laparoscopic surgery). These techniques allow patients to recover more quickly and with less pain and less chance of complication.  Michigan Medicine bariatric surgeons participate in the Michigan Bariatric Surgery Collaborative (MBSC), a state-wide quality improvement program aimed at continually improving the safety of bariatric surgery.
