A prospective comparison of bladder versus enteric drainage in vascularized pancreas transplantation

Abstract

Although the number of pancreas transplants has increased significantly in previous years, debate continues concerning the optimum technique for exocrine pancreas drainage. Enteric drainage (ED) has recently been increasingly popular due to the long-term complications with bladder drainage (BD). We prospectively assigned 40 consecutive pancreas transplant recipients to either bladder (n = 20) or enteric (n = 20) drainage. Patient, kidney, and pancreas graft survival rates at 1 year after simultaneous kidney-pancreas transplantation were 95%, 95%, 85%, for BD group and 90%, 85%, 85% for ED group, respectively. Surgical complications were not significantly different between the two groups. The incidence of acute rejection, major infections, and CMV disease were similar between groups. The length of the initial hospital stay was likewise comparable. However, the BD group showed a slight increase in the number of urologic complications, metabolic acidosis, and dehydration. Based on the results of our study, patient and graft survivals were excellent irrespective of technique.
