Multiple small lesions of hepatocellular carcinoma controlled by percutaneous and laparoscopic ethanol injection--a case report.
A 61-year-old man was admitted to our clinic for a liver examination. Ultrasonography revealed multiple echo-rich lesions in both lobes. A laparoscopy showed a liver with an irregular surface, and a 3-mm-sized dark reddish lesion on the inferior surface of the right lobe. alpha-Fetoprotein and plasma protein induced by vitamin K absence or antagonist were normal. A liver biopsy specimen obtained from the small lesion by laparoscopy-guide showed a well-differentiated hepatocellular carcinoma with bile formation. Biopsy specimens obtained later from the 2 echo-rich lesions by ultrasonographic-guide were histologically similar to the lesion laparoscopically observed. Laparoscopic ethanol injection and percutaneous ethanol injection were performed as therapeutic procedures. Recurrence of hepatocellular carcinoma at the treated sites was not observed during the 6-year observation period. Thus, laparoscopy might play an important role in the early detection and treatment of hepatocellular carcinomas on the surface of the liver.
