[Selection of a drainage operation in obstruction of the common bile duct].

Drainage operations were accomplished on extrahepatic bile ducts in 194 patients. It is the authors' opinion that in emergency surgery the operative procedure may be terminated by external drainage only in relative blockade of bile outflow in the duodenal lumen, while in unrelieved complete blockade of bile outflow such drainage seems to be permissible only in patients with an extremely high operative risk. Biliodigestive anastomoses were constructed in 96 patients. In persistant cholemia, cholangitis, signs of hepatic insufficiency the authors construct biliodigestive anastomoses and simultaneously accomplish provisional external drainage of bile ducts.
