Pancreas Transplantation at Mayo: III. Multidisciplinary Management

Abstract

Although pancreas transplantation is a complicated procedure, a good level of success has been achieved because of the introduction of cyclosporine for immunosuppression, improved methods for diagnosing rejection, and a multidisciplinary approach to management. Our immunosuppressive regimen was quadruple therapy with induction by using Minnesota antilymphoblastic globulin. A biopsy technique was instituted in which the pancreas specimens were obtained under cystoscopic direction during episodes of hypoamylasuria. The criteria for rejection episodes were not only biochemical abnormalities but also histologic confirmation and a follow-up to exclude other causes of graft dysfunction. Infectious disease management included use of oral selective bowel decontamination for 3 weeks after transplantation. At the Mayo Clinic between October 1987 and December 1988, 16 patients received pancreaticoduodenal allografts (both kidney and pancreas in 13 and pancreas only in 3 after a prior successful kidney transplantation). In two pancreas and one kidney allograft, function was lost. One patient died of multiorgan failure. The cystoscopically directed biopsy technique was performed 23 times with minimal complications and a 93% success rate. The metabolic results have been excellent; the glycosylated hemoglobulin level was normal 3 to 6 months after transplantation. The quality of life was significantly improved in almost all patients. Nutritional assessment revealed little deterioration after transplantation. With a multidisciplinary approach, the needed answers about the effect of pancreas transplantation on the degenerative complications of diabetes should be forthcoming.
