Has anyone had a successful conversion from an iband to a Gastric Sleeve? I had my band placed 4 years ago...have never lost much weight, lot of esophagus issues with spasms, can't seem to get me in the green zone. I have an appt.soon to discuss with my Bariatric Surgeon. I hope that my insurance (BCBS and Tricare) will pay to have it removed and pay the conversion. Your feedback is appreciated.
