 Your surgery can be revised if it's failed in the past. Failure of bariatric surgery could be for many reasons. I've done a lot of revisionary surgeries where patients didn't have the proper surgery for them before. Surgeries can be translated. You can have a sleeve gastrectomy converted to a gastric bypass. Gastric bypasses can also be reversed. You can have a band removed and converted to a sleeve gastrectomy. So the answer to that question is absolutely. You can have revisionary bariatric surgery or you can have conversion surgeries.
