Hydatidosis: experience with hepatic and pulmonary hydatid disease.
From 1989-1992, 35 cases comprising of 20 hepatic and 15 pulmonary hydatid cysts were seen. Four patients with pulmonary hydatid disease had previous or concomitant hepatic hydatidosis compared to no concomitant pulmonary hydatid disease in the hepatic group. Hepatic hydatid disease had a greater tendency to be right sides, infected and calcified. Anaphylactic reactions occurred in 3 of 20 patients with hepatic hydatid disease against none in 15 patients with pulmonary disease. Management consisted of evacuation, drainage and obliteration of the residual cavity by capittonage in the lung and omentoplasty in the liver. Two patients, one hepatic and one with pulmonary hydatid disease developed infection of the residual cavity. Bronchocystic fistula occurred in 4 pulmonary and cystobiliary fistula in 2 hepatic hydatid disease patients. One patient with severe pleuropulmonary hydatidosis required a thoracoplasty. No recurrences have been noted in either group over a mean follow-up of 11 months (range 3 weeks- 3 years).
