Factors Predictive of Reoperation After Pancreaticoduodenectomy for Pancreatic Cancer

While mortality is low, morbidity remains high for patients undergoing pancreas resections, especially for those who return to the operating room (RTOR). The aim of this study is to identify risk factors for RTOR following pancreaticoduodenectomy (PD) for ductal adenocarcinoma. Logistic regression models were constructed using the 2014 and 2015 National Surgical Quality Improvement Program (NSQIP) Pancreas Targeted database. Preoperative and procedure-related risk factors predictive of RTOR for patients undergoing either classic or pylorus-preserving pancreaticoduodenectomy for pancreatic ductal adenocarcinoma (PDAC) were identified. A total of 1736 patients were included. Multivariable analysis of patients undergoing classic PD demonstrated that an abnormally low preoperative WBC count was significantly associated with RTOR (OR 2.78, 95% CI 1.27–6.06, p = 0.010). For patients who underwent pylorus-preserving PD, the wound classification (OR 3.99, 95% CI 1.75–9.11, p = 0.001) and arterial resection (OR 26.3, 95% CI 7.96–87.20, p
