Abstract
In the treatment of hepatolithiasis, liver resection helps to prevent recurrence and may reduce the incidence of infection by removal of the atrophic tissue. This study was conducted to determine if the affected liver tissue in hepatolithiasis is inflamed or has lowered local immunity by examining the distribution of secretory immunoglobulin A (sIgA) and proliferating cell nuclear antigen (PCNA) in the intrahepatic biliary tracts of 27 patients with hepatolithiasis. Operative specimens were sectioned and stained with avidinbiotin complex, and the labeling index for both sIgA and PCNA was calculated as a percentage of the biliary epithelial cells stained. Cells stained for sIgA increased to a certain point as the cholangitis became more severe; however, in advanced cholangitis, with severe parenchymal atrophy or actively proliferating biliary epithelium, there were fewer cells stained for sIgA than in mild cholangitis. In hepatolithiasis, the decreased local immunity related to sIgA accompanied severe chronic proliferative cholangitis and parenchymal atrophy.
