Prospective Validation of the Pancreatic Fistula Risk Classification by the International Study Group for Pancreatic Surgery (PARIS trial).

This prospective trial shows that the ISGPS pancreas classification is valid. Patients in risk class D are prone to POPF independently of other factors. Therefore, all future publications on pancreatic surgery should report the risk class according to the ISGPS pancreas classification to allow for a better comparison of reported cohorts.
