Pancreas transplant is the curative treatment in diabetes. Most commonly it is done in type 1diabetes and rarely in type 2 diabetes. Especially in those who are on insulin it can be done but the success rate is not very good. It is 10 to 25% and in some centres more than that. In type 2 diabetes along with that kidney transplant is usually done. So it is done usually in those with both kidney failure and diabetes on insulin because the patients have to be on chemotherapy and immunotherapy and immunosuppressants which itself can further lead to diabetes. Hence it has to be done only in those patients who really have not been responding to insulin and have too much fluctuations and sometimes severe hypoglycaemia, unawareness along with renal failure.
