Abstract
Fourteen patients with hepatocellular carcinoma and mild to moderate liver dysfunction and 2 with metachronous liver metastases from rectal cancers underwent central bisegmentectomy of the liver, i.e., en bloc removal of the left medial and right anterior segments. One patient who had undergone preoperative liver artery embolization died in the hospital. Four patients survived without relapse 6–135 months postoperatively. Eleven patients had recurrent tumors, all in the liver remnant, and 2 also had recurrent tumors in the lungs. Six patients who relapsed died 28–93 months postoperatively. Four were alive with disease at 7–89 months, 1 after a second liver resection 54 months after central bisegmentectomy. Six of the 16 patients survived for 5 years or more. The results are favorable for these advanced tumors, often in the presence of liver dysfunction. The indications, technique, and results are discussed.
