Pancreaticoduodenectomy (PD) is a complex procedure performed in patients with malignant or benign tumors of the pancreatic head and periampullary region, associated with high morbidity and mortality rates. Despite dramatic advancements in surgical techniques and perioperative management, reported morbidity and mortality rates following PD are 41.56% and 2.88%, respectively, which remain unsatisfactory. Postoperative pancreatic fistula (POPF) is the most common and clinically significant complication following PD. Therefore, accurate and timely prediction of POPF after PD is necessary to reduce secondary mortality from serious complications and optimize individual patient treatment decisions. This study aimed to determine the predictive risk factors for clinically related postoperative pancreatic fistula (CR-POPF) in the preoperative, intraoperative and postoperative period in patients that underwent PD.
