[Biliary tract in patients with chronic viral hepatitides].

AIM: To characterize motor-kinetic and inflammatory changes in extrahepatic biliary tracts and gallbladder in patients with chronic viral hepatitis (CVH). To ascertain whether there is a pathogenetic correlation between affection of the biliary system and viral infection.

MATERIAL AND

METHODS

The condition of the biliary tract was examined in 183 patients with CVH using fractionated duodenal tubing with biochemical tests and bacteriological investigation of bile, dynamic ultrasonic investigation.

RESULTS

69.9% patients were diagnosed to have dysfunction of the Oddi's sphyncter caused by its hypertonicity, 4.4% patients had hypotonic sphyncter. Hyper- and hypotonicity of the gallbladder were observed in 45.8 and 20.8% patients, respectively. Biliary dysfunction was associated with the process activity but not with a nosological form of the disease. Chronic acalculous cholecystitis was verified in 21.2% patients.

CONCLUSION

Chronic HBV and HCV infections are accompanied with biliary dysfunctions associated with activity of inflammation in the liver. Oddi's sphincter dysfunction in CVH is a risk factor of gallbladder inflammation.
