Abstract: Objective: To discuss the experience of the resection on tumor of the hepatic caudate lobe. Methods: The mothod of operation on the carcinoma of hepatic caudate lobe for 5 patients was retrospectively analyzed. Results: Abscission of the caudate vein by right pathway was applied in all the 5 cases of the group. Part of the caval vein was respectively dissociated from 2 hepatic cancer patients, with dissociation of 4 to 5 caudate veins; total inferior vena cava at the hepatic segments was dissociated and the caudate veins were totally dissociated in 2 cases with angioma and 1 with metastatic liver cancer. All 5 patients left the hospital with good improvement. Conclusion: Mutilation of the caudate veins ensures safety of the operation. In addition, dissection of hepatic hilum, mutilation of arterial and venous tributory of the caudate lobe can reduce the amount of bleeding in the operation.
