[Hydatidosis relapse in children--clinical and epidemiological study].

This study is a retrospective inquiry among children operated for hydatid cyst which were diagnosed with at least one relapse episode. The study-group consisted of 160 children out of which 110 were submitted to at least one surgical procedure and 35 out of 110O presented hydatidosis relapses. The post-operative monitorization of children with hydatidosis must be extended over a 2-year-period (69.29%) time during which most of the relapses occur. The organs being most frequently affected are primary the liver and secondary the lung. The secondary hydatidosis is more frequent "at distance" from the residual cavity than "in situ". The parasitic control is centered on the imagistic test: abdominal ultrasound, lungradiography and the serological surveillance of specific antibodies of IgG class which can remain positive during the whole life with decreasing titers in time. The antiparasitic treatment pre- and post- operative can complete the therapeutic schedule in the case of hydatidosis in order to assure the recovery.
