RESUMEN
Objective To investigate the clinical application of ultrasound-guided percutaneous puncture aspiration and sclerotherapy of liver hydatid cysts.Methods Thirty-eight patients of hepatic hydatid cysts underwent ultrasound-guided percutaneous puncture aspiration and sclerotherapy;then 20%-25%septic hypertonic saline or 95%absolute alcohol were injected into the cysts (the volume was about 25%-50%of the aspirated fluid) ;and the fluid was reaspirated after 5-15 min.At last,5-10 ml sclerosing agent was injected again.Oral albendazole 30-50 mg/kg was administrated to all patients before and after the above procedures.Ultrasonic follow-up was performed at 3-month interval in the first year and once a year afterwards.Results The successful rate of once puncture was 100%.Aher 6 months,cysts volume reduced 50% in 16 patients,reduced 30% in 22 patients.One year later,34 patients were cured,3 were effectively treated and 1 was improved.All hydatid cysts volume gradually decreased and calcification occurred.The total cure rate was 100%. Conclusion Ultrasound-guided percutaneous puncture aspiration and sclerotherapy is a safe,effective and reliable treatment of liver hydatid cysts.
