After recalling the latest finding on the pathological anatomy, physiopathology, symptomatology, diagnosis and surgical therapy of hepatic echinococcus with intrahepatic bile duct fistulas, the personal series and that of the Palermo Surgical Pathology School is illustrated. These series included 12 patients. The surgery employed is analysed and results obtained reported. It is concluded that modern diagnostic methods, particularly intraoperatory, the new radical surgery techniques, and the improved post-operative assistance offer better chances of success in this condition, reducing both mortality and postoperative complications.
