We underwent microwave coagulation therapy (MCT) for 24 patients with 31 liver cancer from Jan, 1998 to Mar, 2000 (including 23 patients with hepatocellular carcinoma and one with cholangiocellular carcinoma). The approach to the nodules were percutaneous (PMCT) in 19 patients, open surgical (OMCT) in 3 and both in two. Twenty-one nodules out of 23 were well controlled by these MCT therapies. However, two tumors by PMCT were not completely coagulated and required Lipiodol-TAE after PMCT. The OMCT effectively ablated in eight tumors out of 5 patients and no tumor recurrence was noted.There were four complications in three patients. Those included skin burn, bile leakage at the puncture site, obstructive jaundice due to bile duct stricture and infected biloma with bleeding.Infected biloma was occurred in the patient who had undergone a trisegmentectomy of the liver with the reconstruction of choledochojejunostomy for cholangiocellular carcinoma.PMCT and OMCT were the effective treatment of the patients with primary hepatic carcinoma, whose reserved liver function was poor. Attention should he taken to the patients who has a past history of biliary duct reconstruction.
