I do not do bands any more and most of the bariatric surgeons in my area do not either. However it sounds like you did well with the gastric band. How much it costs to fix a hole in the band depends on where the hole is. If it is in the port, you need to have the port changed. If it is in the catheter, most band catheter are long enough so that you just cut the part with the hole and re-connect. Both of these issues can be fixed under local anesthesia at an ambulatory surgery center. If the hole is in the band it self, then the band will need to be replaced. A new band out of the box costs $2500 to $3500 plus anesthesia and surgeon's fee. Depending where you have done hospital vs ambulatory surgery center the cost will be $6500 to $8000.
