Validation of original and alternative fistula risk scores in postoperative pancreatic fistula

Background In 2013, the fistula risk score ( FRS ) was developed to assess the risk of clinically relevant postoperative pancreatic fistula ( CR ‐ POPF ). In 2017, the alternative FRS (a‐ FRS ) was proposed. The purpose of this study was to validate the original FRS (o‐ FRS ) and a‐ FRS for CR ‐ POPF in pancreaticoduodenectomy ( PD ).
