Abstract
We treated 9 patients with HCC by microwave coagulation under laparoscopy from April 1995 to December 1996. After observation of the surface of the liver during laparoscopy as usual, the lesions were punctured with the electrode needle, coagulated with 60 to 80 W for 45 seconds, and freed from the needle by passage of 20 mA for 15 seconds. In the 9 patients, 5 lesions were identified by the usual laparoscopic methods, but the 4 other lesions were not identified. These 4 lesions could be identified by laparoscopic ultrasonography and coagulated. Only one patient had severe pain during treatment, and dynamic CT showed that the lesion was not coagulated sufficiently, so percutaneous ethanol injection therapy was done. The lesions of the 8 other patients seemed to be coagulated sufficiently.
