Surgical resection is the optimal treatment for hepatocellular carcinoma (HCC), however, in patients with liver cirrhosis, major hepatectomy is dangerous because of impaired liver function. We performed partial resection of the liver using microwave tissue coagulator (minimal invasive hepatectomy : MIH) in 14 cirrhotic patients with HCC smaller than 3 cm in diameter. Among 14 patients, 10 patients had hepatectomy with thoraco-abdominal approach. The blood loss during operation was 247 ± 95 ml, and only one patient had allogenic blood transfusion. We had not experienced postoperative major complications, and mean postoperative hospital stay was 18.5 ± 7.4 days. The serum interleukin-6 level at 1st postoperative day was 176 ± 48 pg/ml, which was significantly (p<0.05) lower than that in patients with major hepatectomy for HCC. Thus the partial resection of the liver using a microwave coagulator is considered to be less invasive, safe and useful method for cirrhotic patient with small HCC.
