Merits of percutaneous low output microwave tissue coagulation therapy (PLMCT) is following that coagulation area is distinctly observed by ultra-sonography, because of no bubbling through irradiation. PLMCT can be performed under local anesthesia. Size of coagulation area by PLMCT and high output PMCT are the same.The possible use of PLMCT using ultra-sonography under local anesthesia for small solitary recurrent or metastatic liver cancer was studied.The subjects were 19 patients having recurrent or metastatic liver cancer with solitary liver tumor less than 4 cm in diameter between September 1994 and July 2010.No tumor recurrence was recognized in the coagulation area. Thus, the results suggest that PLMCT is a useful therapy for small solitary liver cancer especially, recurrence of hepatocellular carcinoma as a local control.Key words: percutaneous low output microwave tissue coagulation therapy, metastatic or recurrent liver cancer, needle electrode 1 mm in diameter

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.
