[Clinical treatment of hepatic and abdominal hydatid cyst by percutaneous puncture, drainage and curettage].

Since 1986, we have treated 302 cases with hepatic and abdominal hydatid cyst (361 cysts) by the method of percutaneous puncture, drainage and curettage combined with systemic drug and local drug administration with 5 years' follow-up. The rate of success of percutaneous puncture, aspiration, drainage and curettage was 99%. Only one case presented allergic reaction. At 6 months after the PPDC, 97.2% (212/218) of the cysts had stopped growth. One year later, 84.4% (130/154) of the cysts had disappeared. Five years' follow-up revealed that 77.8% (14/18) of the cysts had disappeared. All of the above-mentioned cases have recovered except for two cases suffered from recurrence of primary cysts resulting from a drop of the cannulas. No serious complications or death had been found.
