RESULTS OF SURGICAL-TREATMENT OF HEPATIC HYDATIDOSIS - CURRENT THERAPEUTIC MODIFICATIONS

Hepatic hydatidosis is an endemic disease that affects vast segments of the populations of various countries in the Mediterranean region, South America, the Pacific, and temperate zone nations that possess large numbers of sheep. Four hundred and ten patients bearing 561 hydatid cysts were treated at 2 major hospitals in Madrid, Spain in the period 1974-1989. In order to establish the modifications in diagnostic and therapeutic management introduced as a result of modernization of our clinical facilities and improved technological standards, they were divided into 2 groups: group A corresponded to the period 1974-1984, and group B, corresponded to the period 1985-1989. Since no effective parasiticide agent is available, hepatic hydatidosis must be treated surgically. Today's better knowledge and advancements in liver surgery have made it possible to extirpate the cyst completely with little risk and improved results; hepatic resection should only be considered in exceptional cases; aspiration, drainage procedures, or partial resections of the cyst yield inferior results. We have had no relapse of the hydatid disease in the liver or in any other abdominal site.
