[Drainage for external draining of biliary tract].
A specially designed surgical drainage for biliary tracts provides safe fixation and easy and minimally traumatic removal. There are no conditions for internal rotation of the tube, and the presence of a few openings in an active part of the drainage in combination with two channels prevent disorders of the drainage function in case of clogging of some of the openings. An opportunity to control the working shape during the removal of the drainage is considered to be its important advantage. The drainage can be adyiested to the shape of hepaticocholedoch. Besides, there is an opportunity of unloading the terminal part of choledoch and evacuating the regurgitation of a pancreatic secret. The design of the drainage prevents narrowing of the choledoch in the region of choledochotomy opening. The proposed variant of the drainage can be easily created in any operating room.
