[Oblique-transverse approach to the extrahepatic bile ducts].

A new access to extrahepatic bile ducts is proposed which keeps the lateral abdominal muscles and intercostal vascular-nervous plexuses intact. The spatial conditions of the access were studied experimentally in 108 corpses. The clinical assessment was tested in 102 operations in comparison with the Kocher access. The oblique-transversal access was found to have advantages from the clinico-physiological viewpoint as well (the development of the postoperative period, restoration of the external respiration function and the function of the abdominal wall muscles).
