This paper reports the cases of obstructive jaundice of hydatid nature operated at the I-st Surgical Clinic of Iaşi between 1979 and 1989. These cases have raised special problems of diagnosis, needing complex investigations. An important role in diagnosis had sonography. The type of surgery depended on the position and nature of the obstruction, the local and distant morphological and functional changes induced by it and the findings at cholangiography.
