We examined surgical complications among a group of diabetic type 1 patients (IDDM) with end-stage renal disease (ESRD) who had undergone pancreas-kidney transplantations (PK). Between October 1993 and August 2004, 70 SPK were performed using bladder (n = 14) or enteric (n = 56) drainage. Donors were selected according to standard criteria (mean age, 27.6 years; range, 17-49). All patients received cyclosporine-based immunosuppression. All pancreata functioned immediately, whereas 2 patients needed postoperative dialysis. Four patients (5.7%) lost their pancreatic graft due to vascular thrombosis; both patients underwent urgent allograft pancreaectomy and pancreas retransplantation (re-PT). One of them (1.4%) experienced a venous thrombosis and died due to a pulmonary embolism at 12 hours after re-PT. The other 3 patients had uneventful postoperative courses and were discharged with good pancreatic and renal function. Three patients in the bladder group (21.4%) had an anastomotic leak, which resolved with a bladder catheter. Four patients in the enteric group (7.1%) who experienced an anastomotic leak needed a second surgical procedure but in 3 of them allograft pancreatectomy was necessary. Relaparotomy was required in the other 3 patients due to hemorrhage (1 patient) or occlusion (2 patients). Acute rejection episodes, which occurred in 16 patients (22.8%), were treated with steroid boluses. With a mean follow-up of 72 months (range, 3-129), 2 patients have died at 8 and at 36 months, respectively, after SPK due to acute myocardial infarction (2.9%). Chronic rejection was the leading cause of pancreatic failure in 5 patients (7.1%) and of renal failure in 2 patients (2.8%). Patient, kidney, and pancreas survival rates were 95.8%, 92.9%, and 81.5%, respectively. Surgical complications were the leading cause of pancreatic allograft loss in IDDM and ESRD patients submitted to SPK.
