In a prospective clinical-experimental study, 15 patients with chronic pancreatitis operated consecutively due to severe pain were examined for the effects of a duodenum-preserving resection of the pancreas head on endocrine pancreas function. This was done by means of oral and intravenous glucose tolerance testing before the operation, on the 10th or 11th postoperative day, and three months after the operation. In addition to glucose levels in the peripheral venous blood, levels of insulin, C-peptide,
glucagon
, somatostatin, and pancreatic polypeptide were determined. As indicated by the k-value, glucose tolerance improved postoperatively in 11 patients; two patients showed no change, and one patient was worse. Only one patient developed evident diabetes mellitus immediately postoperatively. The pre- and postoperative levels of insulin and C-peptide showed no significant differences. The fasting levels of
glucagon
were significantly lower postoperatively than before the operation (2p less than 0.01).
Duodenum
-preserving pancreas head resection led to improvement of the glucose tolerance in the majority of patients; a deterioration was observed only in two cases.

In a prospective clinical-experimental study, 15 consecutive patients with chronic pancreatitis, operated on because of severe pain, were examined for the effects of a duodenum-preserving resection of the pancreas head on endocrine pancreas function. This was done by means of oral and intravenous glucose tolerance testing before the operation, on the 10th or 11th day postoperatively, and 3 months after the operation. In addition to glucose levels in the peripheral venous blood, levels of insulin, C-peptide,
glucagon
, and pancreatic polypeptide were determined. As indicated by the k value, glucose tolerance improved postoperatively in 10 patients (66.6%); three patients (19.9%) showed no change, and one patient (6.6%) was worse. Only one patient (6.6%) developed evident diabetes mellitus immediately postoperatively. Pre- and postoperative levels of insulin and C-peptide showed no significant differences. The fasting levels of
glucagon
were significantly lower postoperatively than before the operation (p < 0.01). The stimulation of pancreatic polypeptide after oral glucose was significantly lower postoperatively (p < 0.01).
Duodenum
-preserving pancreas head resection does not lead to an impairment of glucose tolerance in the majority of patients; a deterioration was observed only in few cases (13.3%).
