Methods: Thirty-one patients surgically treated by hemihepatectomy combined with caudate lobectomy were retrospectively studied. The primary lesions included hepatocellular carcinoma(n=16), hilar cholangiocarcinoma(n=5), giant hemangioma(n=3), hepatolithiasis(n=4), hepatic metastasis(n=1), liver injury(n=1), hepatic inflammatory pseudotumor(n=2). Sixteen of the total were operated with right hemihepatectomy combined with caudate lobectomy and fifteen of them with left hemihepatectomy combined with caudate lobectomy. Result: The average operating time was 218±61 min(130min~367min). The average amount of blood loss was 350±283 ml(80ml~1100ml). Nineteen of the total were not given transfusion because their blood loss were less than 300ml during operation. The perioperative mortality was 0 and total morbidity was 35.5%(11/31), including pleural effusion(n=5), fat liquefaction of incision(n=2), slight hepatic encephalopathy(n=1), biliary leakage(n=3). All complications were treated successfully without operation. Conclusion: Liver lesions involving caudate lobe, either benign or malignant, could be safely and effectively by hemihepatectomy combined with partial or whole caudate lobectomy.
