概要	BACKGROUND:Although more patients have long-term survival after pancreatectomy, the details of pancreatogenic diabetes mellitus (DM) are still unclear. We aimed to investigate the incidence of new-onset DM (NODM) after distal pancreatectomy (DP) and to clarify the risk factors, including allowable pancreatic resection rate (PR), for NODM.METHODS:The incidence, onset time, and risk factors for NODM were retrospectively evaluated in 150 patients who underwent DP without preoperative DM and with >5 years of postoperative follow-up between 2005 and 2015.RESULTS:The incidence rate of NODM was 39%, and 60% of this incidence was noted within 6 months postoperatively. In the multivariate analysis, hemoglobin A1c ≥ 5.8% (odds ratio [OR] 7.6), impaired glucose tolerance and/or impaired fasting glucose (OR 4.2), homeostasis model assessment of insulin resistance ≥1.4 (OR 5.5), and insulinogenic index <0.7 (OR 3.9) were the preoperative risk factors for NODM. Based on these four preoperative risk factors of NODM, we made the new scoring system to predict the NODM after DP. The NODM incidence was 0%, 8%, 48%, 60%, and 86% in patients with risk scores 0 (n = 25), 1 (n = 36), 2 (n = 33), 3 (n = 35), and 4 (n = 21), respectively. PRs ≥42.1% and ≥30.9% were allowable in the preoperative risk-score 0-1 and 2-4 groups. In the former group, the NODM incidence for PR ≥ 42.1% and <42.1% was significantly different (20% vs 0%, P < 0.05). In the latter group, the NODM incidence for PR ≥ 30.9% vs <30.9% was significantly different (75% vs 23%, P < 0.05).CONCLUSIONS:We clarified the preoperative risk factors and allowable PR for NODM and recommended the use of a risk scoring system for predicting NODM preoperatively.
