In order to increase the area of tissue coagulation in liver cancer, we developed a multi-channel microwave coagulation therapy (MMCT) using numerous Teflon-coated electrodes. However, with MMCT we found that it was extremely difficult to treat tumors located deep in the liver. In this study we investigated the advantages of MMCT for cancer located deep in the liver, with a newly devised guidance needle. At first, the guidance needle under ultrasonographic guidance was used to puncture the resected livers of pigs. Numerous electrodes fixed up by spacers were then successfully inserted into the same part along the needle. We concluded that MMCT with the guidance needle was a very useful therapy for cancer located deep in the liver.
