title: Long-term pancreatic endocrine function following pancreatoduodenectomy with pancreaticogastrostomy.
abstract: OBJECTIVE
  The aim of this study was to evaluate long-term pancreatic endocrine function following pancreatoduodenectomy with pancreaticogastrostomy.
  
  
  METHODS
  Records of 52 patients who had survived for three or more years following pancreatoduodenectomy with pancreaticogastrostomy were studied retrospectively. Serum HbA(1c) levels had been measured prior to and at 3- to 6-month intervals after surgery.
  
  
  RESULTS
  Three of 42 patients with normal preoperative serum HbA(1c) levels (<or=5.8%), and five of 10 patients with elevated preoperative serum HbA(1c) levels (>5.8%) showed deterioration of glucose tolerance. Five of these eight patients developed a pancreatic fistula postoperatively. However, the average serum HbA(1c) levels of patients with normal preoperative serum HbA(1c) levels have remained within the normal range for 3-10 years after surgery.
  
  
  CONCLUSIONS
  Pancreatic endocrine function was maintained for a long-term period after pancreatoduodenectomy with pancreaticogastrostomy. Impaired glucose tolerance appeared to be associated with postoperative pancreatic fistula formation.
