Blood glucose control and risk of progressing to a diabetic state during clinical follow up after cephalic duodenopancreatectomy

Abstract Introduction Pancreatic resection carries a theoretical risk of developing diabetes; however few studies have demonstrated the effect of a cephalic duodenopancreatectomy on postoperative blood glucose control. Material and methods An analysis was made of the post-operative clinical follow up of 70 patients subjected to a cephalic duodenopancreatectomy in our Hospital between March 1993 and November 2009. The surgical indication was due to primary pancreatic disease in 30 patients (21 adenocarcinoma of the pancreas, 6 chronic pancreatitis, 1 endocrine carcinoma, 1 cystadenoma and 1 complicated pseudocyst). The pancreas was not affected in the other 40 patients (24 ampullary carcinomas, 11 cholangiocarcinomas, 3 duodenal carcinomas, 1 papillary adenoma and 1 adenomatous hyperplasia of the bile duct). Data on the pre- and post-operative diabetic state were collected. Results Before resection, 49 patients (70.0%) had a normal glucose without the need for treatment. Seventeen patients required oral diabetic treatment, 3 subcutaneous insulin, and only one was treated by diet. The duodenopancreatectomy worsened glucose control in 47.1% of the patients (23 of the previously non-diabetics and 10 of those treated with oral diabetics). Glucose control was worse when the surgical indication was due to primary involvement of the gland (progression of 63.3%) compared with patients with disease (progression of 35.0%) (P  Conclusions Our results show that resection of the head of the pancreas favours the appearance of post-operative diabetes, particularly when the surgical indication is due to primary pancreatic involvement.
