Introduction
This study aimed to determine risk factors for exacerbation of diabetes mellitus (DM) after pancreatectomy.
Methods
Medical records of 167 patients with benign and malignant pancreaticobiliary diseases who underwent pancreaticoduodenectomy or distal pancreatectomy were retrospectively analyzed. DM was diagnosed by diabetic history or American Diabetes Association criteria. Worsened and improved DM after pancreatectomy was defined when treatment intensity or insulin/oral antidiabetic drug dosage increased or decreased, respectively, postoperatively. Long-standing DM was defined as a duration of >2 years.
Results
In 76 preoperative diabetic patients, worsened and improved DM was observed postoperatively in 46 (60.5 %) and 9 (11.8 %) patients, respectively. In 91 preoperative nondiabetic patients, 22 (24.2 %) developed new-onset DM after pancreatectomy. Multivariate logistic analysis of the preoperative diabetic patients demonstrated long-standing DM and malignancy as independent predictors for postoperative worsened DM. No patients with long-standing DM or insulin treatment experienced improved DM after pancreatectomy. Multivariate logistic analysis of the preoperative nondiabetic patients showed body mass index of ≥25 and hard pancreatic texture as independent risk factors for new-onset postoperative DM.
Conclusions
These results may enable preoperative evaluation of risk factors for worsened or new-onset DM after pancreatectomy and may help plan intensive care for patients at a high risk of postoperative worsened DM.
