Abstract

BACKGROUND:

Pancreatic diseases and pancreatic surgery usually cause a derangement of glucose metabolism ranging from a change in glucose tolerance test to insulin-dependent diabetes. The authors assess the changes in glycemia both in basal condition and after a challenge test in a group of patients who underwent Pylorus Preserving Pancreatoduodenectomy (PPPD) according to an original technique of reconstruction with two separate bowel loops.

MATERIALS AND METHODS:

Ten patients who underwent PPPD either for chronic pancreatitis or ampullar carcinoma were enrolled in this study. Pre- and postoperative assessment of pancreatic endocrine function was carried out in all the patients. The evaluation included: 1) oral glucose tolerance test (OGTT), 2) intravenous glucose tolerance test (IVGTT) and 3) glucagon challenge test.

RESULTS:

Plasma glucose level in basal condition, after oral glucose tolerance test, intravenous glucose tolerance test and glucagone challenge test, shows that insulin secretion and/or its effectiveness is not impaired after PPPD. Two patients with preoperative insulin-dependent diabetes needed a lower dose of insulin in the postoperative period. One patient responded abnormally to OGTT both in the preoperative and postoperative periods. Seven patients maintained normal glucose homeostasis in the postoperative period.

DISCUSSION:

PPPD allows a normal control of glucose metabolism. Better digestive and endocrine function noted in our patients in the postoperative period is due to the integrity of the stomach and the reconstruction technique with two bowel loops used to drain biliary and pancreatic secretion separately.
