Perioperative Blood Transfusion Is Associated with Decreased Survival in Patients Undergoing Pancreaticoduodenectomy for Pancreatic Adenocarcinoma: a Multi-institutional Study

Introduction In this multi-institutional study of patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma, we sought to identify factors associated with perioperative transfusion requirement as well as the association between blood transfusion and perioperative and oncologic outcomes. Methods The surgical databases across six high-volume institutions were analyzed to identify patients who underwent pancreaticoduodenectomy for pancreatic adenocarcinoma from 2005 to 2010. For statistical analyses, patients were then stratified by transfusion volume according to whether they received 0, 1–2, or >2 units of packed red blood cells. Results Among 697 patients identified, 42 % required blood transfusion. Twenty-three percent received 1–2 units, and 19 % received >2 units. Factors associated with an increased transfusion requirement included older age, heart disease, diabetes, longer operative time, higher blood loss, tumor size, and non-R0 margin status (all p
