[Cholelithiasis in congenital cysts of the hepatic ducts].

The article describes two cases (0.04%) of congenital cystic cholangiectasia complicated by cholelithiasis, which was revealed among 4,800 patients who underwent operation on the biliary tract. The disease was recognized during surgical intervention, retrograde cholangiopancreatography, and computed tomography. The authors carried out hepatoenterostomy with the use of a loop of the small intestine excluded after Roux and formation of choledochoduodenal anastomosis. Biliodigestive anastomoses create good conditions for the passage of bile and concrements from the ducts.
