Successful percutaneous treatment of extrahepatic cystic echinococcosis through PAIR and single puncture catheter techniques.

PURPOSE: To demonstrate the successful percutaneous treatment of extrahepatic cystic echinococcosis as an alternative to surgical procedures.

MATERIALS AND

METHODS

A total of 27 extrahepatic hydatid cysts in 12 patients, the spleen in 8 patients, muscles and soft tissues in 3 patients each and right adrenal gland in 1 patient were treated with PAIR (puncture, aspiration, injection, respiration) or single puncture catheterization methods. As a scolicidal and sclerosing agent, alcohol was used in all patients.

RESULTS

Of 27 extrahepatic lesions of hydatid cysts, 24 (88.9%) were Gharbi type 1 (WHO CE 1), and 3 (11.1%) were Gharbi type 2 (WHO CE 3A). Of hydatid cystic lesions, 20 with PAIR and 7 with single puncture catheterization methods were treated. No major complications developed in any patients. Abscesses were detected in two patients (16.6%). Mean total hospital stay was calculated between 1 and 14 days (mean 2.3 days). Follow-up periods ranged between 10 and 62 months (mean 22.3 months).

CONCLUSION

Percutaneous treatment for extrahepatic hydatid cystic lesions is an important alternative to surgical procedures because of the high therapeutic success rate, lower rate of complications and shorter hospital stays.
