METHOD FOR ENDOSCOPIC BOUGHING OF CHEAP RIM STRUCTURES USING ORAL CHOLOPHOSCOPE

摘要

A method for endoscopic boughening of cicatricial choledoch strictures, characterized in that if it is not possible under the radiological control to conduct the conductor beyond the stricture into the choledoch lumen, through the instrumental channel of the duodenoscope, an oral choledochoscope is inserted and through its instrumental channel, under visual control, using the controlled distal end of the choledochoscope, a conductor is started for the area of cicatricial stricture with subsequent bougienage along the established conductor.
