    Abstract:
    BACKGROUND: Due to improvements in imaging techniques and immunodiagnostic methods there has been a spurt of cases of hepatic hydatidosis. Till now surgical management in the form of marsupialization and tube drainage, omentoplasty or hepatectomy was the mainstay of treatment. Recently treatment options have improved considerably after introduction of the PAIR (precutaneous aspiration, injection of scolicidal agent and reaspiration) procedure. In this study we report the results of ultrasound guided PAIR procedure in 39 hepatic hydatid cysts. METHOD: All patients with hepatic hydatid cysts underwent the PAIR procedure under ultrasound guidance. The scolicidal agent used was 20% hypertonic saline. Type I and II (n=24) cysts were managed by precutaneous aspiration while type III and IV showing a multiloculated or pseudotumour appearance (n=15) cysts were managed by the percutaneous placement of a Malecot's catheter which was removed after 3-7 days. RESULTS: All patients responded to the PAIR procedure. The commonest ultrasonographic appearance in hepatic hydatid cyst patients was a solitary uniloculated cyst with prominent back wall echoes in the right lobe of the liver. The complications encountered were in the form of mild hypotension (two cases), urticaria in one patient and severe hypotension leading to shock in one case. CONCLUSIONS: The PAIR procedure was found to be effective, cheap and safe in the non-surgical management of hepatic hydatid cysts.
