Novel risk scoring system for prediction of pancreatic fistula after pancreaticoduodenectomy.

Background: The available prediction models for clinically relevant postoperative pancreatic fistula (CR-POPF) do not incorporate both preoperative and intraoperative variables.

Aim: To construct a new risk scoring system for CR-POPF that includes both preoperative and intraoperative factors.

Methods: This was a retrospective study of patients who underwent pancreaticoduodenectomy (PD) or pylorus-preserving PD (PPPD) between January 2011 and December 2016 at the First Affiliated Hospital of Soochow University.
