Postoperative Pancreatic Fistula in Patients Undergoing Pancreaticoduodenectomy

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. Postoperative pancreatic fistula (POPF) is the most common and clinically significant complication following PD. In this study, the investigators aim to predict pancreatic fistula using the C-reactive protein-albumin ratio (CAR). The total number of participants expected to be included in this research comprises patients who underwent PD between 2017 and 2023 and developed pancreatic fistula. The participants invitation is based on the detection of a pancreatic fistula. This study is conducted for research purposes and participation is voluntary. No interventions will be performed on the participants as part of this study; however, we have prepared this form to obtain participant permission to gather certain information. If the participants consent to the use of information for scientific purposes with the guarantee of confidentiality, they will be asked to sign a consent form.
