Abstract:
OBJECTIVE: To develop and test a scoring system to predict the risks of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy(PD). METHODS: Clinic data and postoperative complications of the 445 consecutive patients who underwent a PD procedure between January 2008 and April 2015 in Peking University First Hospital were retrospectively collected and analyzed.The patients were randomly selected to modelling and validation sets at a ratio of 3∶1, respectively.The patient data were subjected to univariate and multivariate analysis in the modelling set of patients.A score predictive of POPF was designed and tested in the validation set. RESULTS: POPF occurred in 88 of 334 patients(26.4%) in the modelling set.The multivariate analysis showed that body mass index (BMI, P<0.01) and pancreatic duct width(P=0.001) are associated with POPF independently.A risk score to predict POPF was constructed based on these factors and successfully tested.The area under the receiver operating characteristic curve were 0.829(95% CI: 0.777-0.881) on the modelling set and 0.885(95% CI: 0.825-0.945) on the validation set, respectively. CONCLUSIONS: BMI and pancreatic duct width were associated with POPF after PD. The preoperative assessment of a patient's risk for POPF is feasible.The present risk score is a valid tool to predict POPF in patients undergoing PD, to make the selection on anastomosis types, and to take precautions against POPF.
