Endocrine and exocrine pancreatic functions following partial pancreatectomy + partial hepatectomy.

Comparative studies were performed on changes in endocrine and exocrine responses of the pancreas after partial hepatectomy, partial pancreatectomy or combination of these procedures in rats, in order to clarify the effect of the combined operation on the remnant pancreatic parenchyma. Three days after partial (60%) pancreatectomy with partial (70%) hepatectomy, endocrine function was better preserved than after partial pancreatectomy alone, suggesting that hypersecretion of insulin initiated by partial hepatectomy may ameliorate the defective glucose-induced insulin secretion following partial pancreatectomy. Further, exocrine function in terms of amylase output was relatively well maintained 3 days after partial pancreatectomy + partial hepatectomy as compared with partial pan after partial pancreatectomy + partial hepatectomy as compared with partial pancreatectomy alone.
