Background: Percutaneous treatment of the hydatid cyst has been well documented that morbidity and mortality rates, hospitalization time, and recurrence rate associated with percutaneous treatment are significantly less than those with surgery. Objectives: To research the success rate of treatment of hydatid cyst by modified percutaneous treatment using a trocar technique. Patients and Methods: Patients who had intra-abdominal hydatid cyst were treated by a modified percutaneous technique were included the study. This study included patients who were treated between June- 2003 and April-2015. We excluded patients who either had biliary fistula during the intervention or did not participate in the follow-up sessions. Medical treatment with albendazole was performed before and after the procedure. Patients were followed up at 3, 9, 12, 24, 36, and 48 months after the procedure. Results: Out of a total 83 patients, 10 patients had biliary fistula, so they underwent surgical treatment. 13 patients did not come to the controls. As a result, 60 patients who had 72 intra-abdominal hydatid cysts underwent percutaneous ablation treatment. 48 patients who had 59 hydatid cysts were cured after the first intervention. After initial treatment, the success rate was 81, 9%, and after the secondary intervention, the success rate was 94, 4%. The average diameter of cysts that were cured in a single session was 6, 9 ± 2, 2 cm; the average diameter of cysts that were removed during the secondary intervention and surgical treatment was 10, 2 ± 3, 4 cm. Conclusion: Whatever the hydatid cyst size, if a drainage catheter is used for initial puncture using the trocar technique, it will be safer and more comfortable for patients compared with the PAIR or catheterization technique.
