External validation of alternative fistula risk score (a-FRS) for predicting pancreatic fistula after pancreatoduodenectomy

BackgroundThe utility of the proposed alternative fistula risk score (a-FRS) for predicting risk of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD) has not been validated widely.MethodsThis retrospective analysis included data of patients undergoing open and laparoscopic PD during March 2012–May 2018 in our institution.
