[Percutaneous ethanol injection therapy by ethanol mixed with CO2 microbubble for hepatocellular carcinoma].

One of the shortcomings of percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC) is that many sessions are necessary to accomplish the treatment. This may be caused by which the ultrasonography (US) image does not reflect correctly to the kinetics of injected ethanol into HCC nodule. It is considered that number of treatment sessions are able to be reduced if we just enough injected labelled ethanol under US into HCC nodule.

[Percutaneous ethanol injection therapy for hepatocellular carcinoma in hepatic dome directly under right diaphragma--the trial of artificial ascites method].

We tried to infuse 40 approximately 100 ml saline solution into abdominal cavity (artificial ascites method) in case of percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC) in hepatic dome directly under right diaphragma (hepatic dome) which is considered as dead space on ultrasonography. Consequently broad visual field was acquired on ultrasonogram and puncture to HCC in hepatic dome was able to be performed very easily. There were no side effects such as difficult hemostasis and peritoneal dissemination.
