| Hydatid still represents a serious problem in endemic areas. Medical treatment, aspiration of the cyst, laparoscopy, and surgical intervention all were used in the treatment of hydatid cyst. This study was assessing cases of hydatid cysts presented as urgent cases; in respect to their location, age and sex, type of presentation, surgical procedures, and results of surgery. Out of 94 patients operated upon for hydatid cyst, 20 were urgent. Urgent presentation included obstructive jaundice, infected hydatid cysts with intra-abdominal abscess formation and a patient with pressure effect on the cerebral hemisphere. Type of surgical treatment depends on site of the cyst, size of the cyst, and type of complications. The liver was affected in 18 out of the 20 urgent patients; one affected the spleen, and another the brain. The average age of the patients was 44.5 years; 13 were females (67%). Ten patients were operated upon for obstructive jaundice, 6 for intra- abdominal abscess, 3 for intraperitoneal rupture of the hydatid cyst, and one patient was sent to the neurosurgical department due to cerebral hydatid cyst. The mean hospital stay was 12 days .Postoperative complications followed four operations including one of billiary fistula, and two of persistent obstruction of common bile duct following surgery for obstructive jaundice; while one patient developed subphrenic abscess following operation for intra-abdominal abscess in the spleen. No mortality occurred. Most of the cases of hydatid cysts are operated upon selectively. Urgent hydatid cysts patients are of great concern to the surgeons in endemic areas. Obstructive jaundice represents the most common cause of urgent hydatid cyst surgery and is associated with highest morbidity and hospital stay. Despite the high morbidity and long hospital stay following urgent surgery, no mortality occurred and all the patients discharged in good condition |
