Chromoholography

Chromocholithography is a method of visualizing the bile ducts using a dye that is removed from the gallbladder and hepatic ducts. The technique is widely used in gastroenterology to assess the condition of the bile ducts and assess their patency.

The method allows you to determine the state of the biliary system in case of changes in liver function, gallstones, as well as pathology of the bile ducts.
