A 70-year-old man was admitted for suspected hepatocellular carcinoma (HCC). Abdominal CT detected a tumor mass 2.5 cm in diameter protruding from the surface of the right lobe of his liver. We decided to perform radiofrequency ablation (RFA) with laparoscopic guidance. Laparoscopy revealed the HCC being adjacent to the costae on the outermost side of the right lobe; it was difficult to safely puncture an electrode needle into the tumor. Hence, we infused normal saline (artificial ascites) into the space between the liver and abdominal wall, and then performed percutaneous RFA with ultrasonography guidance. Using this laparoscopic artificial ascites technique, we could safely and easily perform ultrasonography-guided percutaneous RFA for HCC on the outermost side of the right lobe of the liver, which is otherwise difficult to treat by laparoscopic or percutaneous approach.
