Diagnosis of bile ducts lesions in echinococcosis of the liver

: The results of examination and surgical treatment of 277 patients with hepatic echinococcosis with bile ducts lesion are analyzed. Symptoms of bile ducts lesion serve the indication for direct roentgenocontrast methods of bile ducts examination (endoscopic retrograde pancreaticocholangiography, percutaneous transhepatic cholangiography, fistulography). Jaundice in anamnesis, dilatation of hepaticocholedoch, abundant outflow of bile from residual cavity after echinococcectomy require additional examinations during surgery (USE, cholangiography, chromatic reaction). Instant chromatic diagnosis of internal cystobiliary fistulas is highly informative, particularly in cases when complete revision and visualization of wall of residual cavity is impossible.
