Nevertheless, the results were inconsistent. The true rate of NODM after distal pancreatectomy (DP) is still unknown.Research design and methods The aim of this study was to investigate the incidence of and the risk factors for NODM after DP. This study enrolled patients who underwent DP between January 2004 and February 2016 at Peking Union Medical College Hospital. Patients with preoperative diabetes mellitus or diagnosed with pancreatic cancer were excluded. The primary outcome was NODM.Results A total of 485 patients were enrolled. The median (IQR) of follow-up duration was 30.95 (9.26–180.30) months. The accumulative incidence of NODM was 8.9% at postoperative 6 months, 14.0% at postoperative year one, 22.3% at year three, 27.1% at year five, and 35.5% at year ten. Multivariate analysis showed that the risk of postoperative NODM was positively correlated with age (HR 1.029 (1.013–1.045), p<0.001), preoperative body mass index (BMI) (HR 1.042 (1.003–1.083), p=0.001), operative blood loss (HR 1.0003 (1.0002–1.0010), p<0.001), and length of resected pancreas (HR 1.079 (1.013–1.148), p=0.017). Moreover, concomitant splenectomy (HR 2.001 (1.202–3.331), p=0.008) was associated with significantly higher risk of postoperative NODM.Conclusion NODM incidence increased with postoperative time progression. Age, BMI, surgical blood loss, length of resected pancreas and splenectomy were independent risk factors for NODM after DP.Trial registration number NCT03030209.
