Abstract

PURPOSE
To compare the effect of local injection therapy with absolute ethanol and hot-saline in the normal liver of rat.
MATERIALS AND METHODS
An experimental study was performed with the normal liver of 52 rats. The resected livers were pathologically analyzed on three days, one week, two weeks, and four weeks after injection of 0.1 ml absolute ethanol and hot-saline. The assessment was done in view of 1) main pathologic changes on time, 2) pattern of inflammatory cell infiltration, 3) measurement of necrotic area, 4) effect on vascuar and biliary tracts adjacent to necrotic area, and 5) extrahepatic peritoneal adhesion.
RESULTS
The main pathologic changes were acute necrosis with inflammation for three days group and secondary regenerative fibrosis in all groups. The degree of necrosis was significantly more severe in absolute ethanol injection group, demonstrating larger necrotic area, than hot-saline injection group. The effect on vessels and bile ducts adjacent to the necrotic area was almost not seen in both groups. The extrahepatic peritoneal adhesion was noted in both groups, but the degree was more prominent in the absolute ethanol injection group than hot-saline injection group.
CONCLUSION
Absolute ethanol is superior to hot-saline in the necrotic effect of percutaneous injection therapy. However, hot-saline could be applied in case of the borderline area between mass and adjacent normal liver or the subcapsular mass.
