Abstract

We investigated the long-term efficacy and the contraindications of single-session percutaneous ethanol injection (PEI) under general anesthesia in hepatocellular carcinoma (HCC). One hundred patients were treated from October, 1991, to April, 1996: 24 patients had a single capsulated HCC, 4.5 to 10 cm phi (group A); 62 had a single infiltrating tumor or multiple lesions (3 to 6), with 10 cm maximum phi (group B); 14 patients were in an advanced stage because of Child class C or of infiltrating tumors with portal thrombosis, with 14 cm lesion maximum phi (group C). Group A patients were treated because they were not operable or refused surgery. Three to 22 injections were performed (mean: 13) depending on tumor size and ethanol spread. The maximum injected volume of ethanol was 190 ml (mean: 57 ml). The procedure took 20 to 50 minutes (mean: 30 minutes). The mean hospital stay was 3.5 days. Tumor necrosis was complete in 58% of encapsulated tumors and > 70% in infiltrating lesions. The greatest lesion with complete post-PEI necrosis was 8.2 cm phi. A transient and variable increase in transaminase, bilirubin, white cell and D-dimer levels and a decrease in red cell, platelet, hemoglobin, fibrinogen and haptoglobin levels were o...Continue Reading
