Laparoscopic microwave coagulation therapy for small hepatocellular carcinoma on the liver surface.
Six patients with small size (< or =2.0 cm in diameter) hepatocellular carcinoma (HCC) on their liver surface underwent laparoscopic microwave coagulation therapy (LMCT) in our institute. All cases showed complete necrosis after LMCT alone and there were no major complications during the LMCT. During the follow-up period, one patient had recurrent HCC at the LMCT-treated lesion site and two patients had lesions at sites distant to the LMCT-treated site. Two out of these three patients had presented with severe liver dysfunction at admission and died within the follow-up period. LMCT is believed to be a useful and safe treatment for small size HCC on the liver surface, and treatment can achieve complete tumor necrosis. However, in severe liver dysfunction, the use of LMCT may have a negative influence on patient survival.
