In Zliten hospital, we operated 400 patients with hepatic hydatidcysts over period of 20 years. All patients were symptomatic. Their ages varied from 3 to 85 years including 215female and 185 male patients. Their symptoms varied from abdominal pain to abdominal mass 67 patients wereadmitted through Accident and Emergency Department with acute presentations including fever, skin rash,jaundice and shock with acute abdominal pain. Those 67 patients had necessary investigations, resuscitation andunderwent emergency surgery. The hepatic cysts in all patients were excised, and the obstructive jaundice wascleared in those patients with obstructive jaundice. Unfortunately, one of the patients died two days after thesurgery because of multiple organ failure (MOF) Morbidity was wound Infection, bile leak and recurrence rate wereall reported in our series.
