title: Grey-scale ultrasonography in the evaluation of primary carcinomas of the bile ducts.
abstract: The authors report the echographic findings observed in 24 proven cases of primary carcinoma of the bile ducts. Most tumours, either vegetating or infiltrating with extraductile extension, were recognized on ultrasound. This technique turned out to be accurate in detecting peripheral, hilar and distal ductal carcinomas. Ultrasonography complements PTC and ERCP. Their combined use allows the surgeon a better selection of the cases and of the proper operative procedure.
