Preoperative Pancreatic Resection (PREPARE) score: a prospective multicenter-based morbidity risk score.

Objectives: Development of a simple preoperative risk score to predict morbidity related to pancreatic surgery.

Background: Pancreatic surgery is standardized with little technical diversity among institutions and unchanging morbidity and mortality rates in recent years. Preoperative identification of high-risk patients is potentially one of the rare avenues for improving the clinical course of patients undergoing pancreatic surgery.
