A new approach to the intraoperative diagnosis of cholangitis and to the choice of surgical procedure in operations on the bile ducts

: The authors have developed a prompt and informative method for assessment of the depth and reversibility of the morphofunctional changes in the common bile duct (CBD) wall with the use of staining by hematoxylin basic, fuchsin-picric acid. Four types of the morphologic changes in CBD wall, which characterize the different degree of reversibility, were established. Depending of presence of these types, the corresponding surgical tactics is recommended.
