Two cases of hepatocellular carcinoma in hepatic dome under right diaphragma using percutaneous microwave coagulaton therapy with artificial ascites method

Abstract

We have employed a new technique, percutaneous microwave coagulation therapy (PMCT) with artificial ascites method, for two patients with small hepatocellular carcinoma (HCC), less than 2.5 cm in diameter, located directly under right diaphragma that was considered as dead space on ultrasonography.
The diaphragma near the tumor was not damaged due to the safety space of infused saline solution between liver and diaphragma.
The tumor was completely enclosed within the coagulated area and no recurrence was showed for 5 months after procedure. We did the procedure under local anesthesia and could repeat it again.
PMCT with artificial ascites method was very useful and low invasive therapy for small HCC directly under right diaphragma.
