Predictive factors for perioperative blood transfusions in laparoscopic colorectal surgery

Background Allogeneic perioperative blood transfusion (PBT) has been associated with higher rates of postoperative complications in patients undergoing colorectal surgery and increased tumor recurrence in cancer patients. Our aim is to evaluate possible predictive factors for PBT, specifically, in patients undergoing laparoscopic colorectal surgery, in order to identify patients who could benefit from alternatives to allogenic PBT such as erythropoietin administration, autologous blood transfusion, and possibly preoperative blood transfusion.
