We report about our experience with combined en-bloc liver-pancreas transplantation in 14 patients with liver cirrhosis and insulin dependent type 2 diabetes mellitus. Exocrine drainage was achieved by duodeno-duodenostomy. Median posttransplant follow-up is currently 92.5 months. All patients were rendered independent from insulin therapy shortly after transplantation. Levels of glycosylated hemoglobin normalized in all recipients. Mean fasting C-peptide values increased from pretransplant 7.0+/-1.7 ng/mL to 10.5+/-2.9 ng/mL 3 months posttransplantation (P<0.001). One recipient (7.1%) developed recurrent exogenous insulin dependence 7 years after transplantation. Pancreas allograft rejection was confirmed by endoscopic biopsy of donor duodenum mucosa in two patients (14.3%). Calculated 5- and 7-year survival is currently at 64.3% and 64.3%, respectively. Our results indicate that combined en-bloc liver-pancreas transplantation using duodeno-duodenostomy is technically feasible and leads to excellent long-term control of glucose metabolism in patients with liver cirrhosis and insulin-dependent type 2 diabetes.
