    Abstract:
    BACKGROUND: The optimal pancreatic exocrine drainage method remains controversial. Bladder drainage (BD) is widely used, but associated with a high incidence of urological complications (acidosis, dehydration, pancreatitis, and urinary tract infection). Enteric drainage (ED) avoids this morbidity, but may be associated with inferior graft survival. METHODS: We conducted a retrospective study comparing BD and ED in 71 simultaneous pancreas-kidney transplant recipients (37 BD; 34 ED) transplanted between February 1988 and June 1996. RESULTS: Five BD and five ED patients experienced early pancreas loss within 3 months after transplantation. The mean follow-up of the remaining 61 patients has been 45.7+/-3.9 and 76.0+/-3.3 months for ED and BD patients, respectively (P<0.005). Both groups had similar pretransplant demographics, co-morbidity, and nutritional and immunological status. The incidence of volume depletion (3.4% vs. 34.3%), acidosis (0% vs. 41.0%), pancreatitis (3.4% vs. 39.7%) and urinary tract infection (26.7% vs. 71%) was lower in ED patients (P<0.005 vs. BD). Of the BD group, 18.7% required conversion to ED for intractable complications. Initial length of stay was equivalent (17.7+/-9 days vs. 18.4+/-10 days) between groups. However, the number of admissions (0.79+/-0.18 vs. 1.38+/-0.14) and in-hospital days/patient/year (6.26+/-1.16 vs. 11.46+/-2.12) was less in ED patients (P<0.05 vs. BD). Actuarial patient and pancreas allograft survival up to 4 years after transplant was similar between groups. CONCLUSIONS: Compared with BD, (a) perioperative morbidity is not increased by ED, (b) ED is associated with fewer complications and hospitalizations, and (c) ED is not associated with increased long-term pancreas graft failure. These data suggest that ED is superior to BD and should be considered as the preferred technique for simultaneous pancreas-kidney transplants.
