title: [Pancreatectomy and diabetes].
abstract: Post total pancreatectomy diabetes is a clearly defined form of unstable diabetes, requiring low doses of insulin, with frequent and severe hypoglycemic events. This is due to both deficiency of pancreatic glucagon, hormone of primary importance for hepatic gluconeogenesis and glycogenolysis, and exocrine failure. The management of this form of diabetes is difficult, involving exact correction of malabsorption and low doses of insulin. Whenever possible, partial pancreatectomy should therefore to be preferred. After partial pancreatectomy, the likelihood of diabetes depends on the volume of the remaining pancreas, the type of resection and above all the preexisting pancreatic status. Prevention of postoperative hyperglycemia could minimize the risk of long-term diabetes. Pancreatic cancer is a particular case: the onset of diabetes could be a manifestation of occult pancreatic cancer and glucose metabolism may improve after tumour excision with preservation of some pancreatic tissue.
