Abstract
During a 7-year period, 116 pancreas transplants were performed in 98 diabetics patients (49 with and 49 without previous kidney transplants) at the University of Minnesota [USA]. The posttransplant clinical course of 26 recipients (22%) was complicated by an intra-abdominal infection (8 with and 18 without previous kidney transplants). Infections occurred in 19/57 cases (33%) in which exocrine secretions were managed by enteric drainage, in 5/15 cases (33%) managed by free drainage into the peritoneal cavity, in 1/39 cases (3%) in which the duct was injected with a synthetic polymer, and in 1/2 cases (50%) in which a pancreaticocystostomy was performed. The organisms Escherichia coli, enterococci, bacteroides, and several anaerobes were cultured from the patients with enteric drainage, while staphylococci were associated with the open duct drainage. Fungal infections with Candida were found with all techniques. Surgical and percutaneous drainage was performed in all patients. In 14 patients, functioning and in four patients, nonfunctioning grafts were removed. In five patients, the infection resolved while the grafts were functioning, and these patients are currently alive and well. Seven of the 26 patients with infections died (27% mortality rate), five after graft removal and two with the graft still in place (1 with 1 without function), five in the open-duct, and one each in the enteric and urinary drainage categories. In the 90 cases without intra-abdominal infection, only six patients died (4 cardiovascular, 1 anaphylaxis, 1 cytomegalovirus infection), for a mortality rate of 7%.
