The management of liver hydatid cysts by percutaneous drainage
Objective:
To investigate the effect of percutaneous drainage on liver hydatid cysts.
Design:
A retrospective case study.
Setting:
Department of Surgery, Selçuk University, Konya, Turkey.
Patients:
Forty-five patients with 83 liver hydatid cysts (types I and II according to the classification of Gharbi and colleagues) followed up for a mean of 30 months (range from 14 to 36 months).
Intervention:
The cysts were drained percutaneously with ultrasonographic guidance and then irrigated with 0.05% silver nitrate solution through a fine needle. Albendazole was administered 48 hours before percutaneous drainage and for 2 months after the procedure to prevent the implantation of spilled scolices.
Main Outcome Measures:
Complications of the procedure, decrease in size of the cyst cavity, recurrence and dissemination of the cysts.
Results:
All the cysts were treated successfully by percutaneous drainage. Anaphylactic shock developed in 1 (2.2 %) patient, and mild allergic reactions were observed in 2 (4.4 %) patients during the interventional procedure. Follow-up ultrasonography and CT demonstrated a statistically significant (p < 0.01) decrease in the mean cyst size. Recurrence and dissemination were not observed during the follow-up period.
Conclusion:
Percutaneous fine-needle aspiration and drainage is effective for managing cystic liver hydatid disease in selected cases.
