Abstract
Although there is a tendency to perform enteric drainage of pancreas transplants in simultaneous pancreas-kidney (SPK) transplantation, bladder drainage is still preferable in pancreas transplantation alone (PTA) or after a previous kidney transplantation (PAK). Our hypothesis was that enteric conversion of a bladder drained pancreas is an effective and safe procedure. We studied the complication rate and physiological effects of enteric conversion in patients with primary bladder-drained SPK transplantation. We performed 51 enteric conversions in bladder-drained SPK transplant recipients. As we observed a low complication rate, with time enteric conversions were also performed for less strict and severe indications. The main indications for conversion were urological problems, metabolic complications and reflux-pancreatitis. The median transplantation-conversion interval was 12 months (range 2-40 months). Post-operative complications consisted of seven urinary tract infections, two low-grade superficial wound infections, one minor bleeding, one phlebitis and one paralytic ileus. In two patients, a relaparotomy was necessary. No graft rejection following enteric conversion was found. Long-term renal and pancreatic function were not affected by the enteric conversion. Three-year patient, kidney and pancreas survival rates after enteric conversion were 93, 97 and 93%, respectively (censored data). Enteric conversion after pancreas transplantation is an effective and safe procedure. Therefore, we suggest a policy of a two-step approach of primary bladder drainage followed by an enteric conversion of the pancreas in a selected group of SPK patients.
