[Cancer of th e exrahepatic bile ducts].

The authors have summarized their experience with observations and treatment of 101 patients with cancer of extrahepatic bile ducts. Based on personal authors' findings it is concluded, that cancer of bile passages can frequently develop against the background of cholelithiasis. Taking into account little efficacy of surgical therapy, the prophylaxis of cancer development, namely an early operation for cholelithiasis, is believed by the authors to be the most effective measure.
