Background. Since 1,982, 288 pancreas transplantations have been perfo
rmed at the University of Wisconsin. This report reviews our experienc
e with 200 consecutive simultaneous pancreas-kidney (SPK) transplantat
ions during a 7-year period. Methods. Two hundred consecutive SPK tran
splantations were performed between December 1985 to October 1992. Imm
ediate posttransplant function and surgical and infectious complicatio
ns were evaluated. Frequency of rejection episodes were analyzed, as w
as 5-year patient and graft survival. Results. All but four pancreas t
ransplants functioned immediately after transplantation. Three pancrea
s transplants failed because of thrombosis and one from primary nonfun
ction. Five-year patient survival was 90.2%, kidney survival 80.3%, an
d pancreas survival 78.6%. There were 54 surgical complications. Fifte
en patients have died since 1985. The most frequent cause of death was
infection (three patients). A total of 678 infectious episodes were r
ecorded. Urinary tract infection (n = 344) was the most frequent type
of infection. Enteric conversion was necessary in 35 patients, with th
e most frequent indication being a leak of the duodenal segment. Concl
usions. We concluded from this series that SPK transplantation is asso
ciated with higher cost and morbidity as compared with kidney transpla
ntation alone. However, excellent long-term survival in combination wi
th the clearly demonstrated benefits for secondary diabetic complicati
ons indicate that SPK transplantation is the procedure of choice for c
arefully selected patients with diabetes.
