One hundred consecutive hepatobiliary resections for biliary hilar malignancy: preoperative blood donation, blood loss, transfusion, and outcome.

BACKGROUND: Many reports on blood loss and transfusion requirements during hepatectomy for metastatic liver cancer or hepatocellular carcinoma have been published; however, there are no reports on these issues in hepatectomy for biliary hilar malignancy. The aim of this study was to review our experience with blood loss and perioperative blood requirements in 100 consecutive hepatectomies for biliary hilar malignancy.

METHODS: One hundred consecutive hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for hilar malignancies were performed, including 81 perihilar cholangiocarcinomas and 19 advanced gallbladder carcinomas involving the hepatic hilus. Fifty-eight hilar resections were combined with other organ and/or vascular resection. Data on preoperative blood donation, intraoperative blood loss, and perioperative transfusion were collected and analyzed.

RESULTS: Preoperative autologous blood donation was possible in 73 patients (3.4 +/- 1.2 U). Intraoperative blood loss was 1850 +/- 1000 mL (range, 677-5900 mL), and it was < 2000 mL in 62 patients. Intraoperatively, only 7 of the 73 patients (10%) who donated blood received transfusion of unheated, homologous blood products (packed red blood cells or fresh frozen plasma), whereas 18 the 23 patients (67%) without donation received homologous transfusions. Only 16 patients received transfusion postoperatively, and overall, 35 patients received unheated homologous blood products. Total serum bilirubin concentrations after hepatectomy in patients receiving autologous blood transfusion only was similar to those in patients who did not receive transfusion. The incidence of postoperative complications was higher in the 35 patients who received perioperative homologous transfusion than in 65 patients who did not (94% vs 52%; P <.0001). The mortality rate (including all deaths) was 3% (myocardial infarction, intra-abdominal bleeding, and liver failure, 1 patient each).

CONCLUSIONS: Despite the technical difficulties arising from hepatectomy for biliary hilar malignancy, approximately two thirds of hepatectomies can be performed in an experienced center without perioperative homologous blood transfusion using preoperative blood donation.
