The case is a 72-year-old-male who was treated with percutaneous transhepatic low output microwave tissue coagulation therapy (PLMCT) using a new needle electrode 1 mm in diameter for metastatic liver tumor in touch with liver surface and the intestine. This needle electrode is more useful than an old type 16 G needle electrode in strength and the point that coagulated tissue is hard to adherent to the electrode. PLMCT was performed at the output of 40 watt for 90 seconds at a time. Tumor 1.7 cm in diameter was completely coagulated by irradiation 2 times and the intestine in touch with the liver surface was preserved judged by enhanced CT.
The results suggested that PLMCT using a new electrode 1 mm in diameter is a useful therapy even for small solitary liver tumor in touch with liver surface.
