Popis: Purpose The purpose of this study was to evaluate the safety and efficacy of sonographically guided percutaneous drainage and irrigation of hepatic hydatid cysts. Methods Sixty-one patients with 84 hepatic hydatid cysts were treated using the puncture, aspiration, injection, and reaspiration (PAIR) technique under sonographic guidance. Patients with cysts larger than 6 cm in diameter underwent PAIR followed by percutaneous drainage (PAIR-PD). The cysts were sterilized by the injection of 1 of 2 scolicidal agents, 20% hypertonic saline solution (38 patients) or 0.5% silver nitrate (23 patients). All patients underwent follow-up examinations for 1 month–6 years after aspiration. Clinical and radiologic examinations and laboratory analyses were performed every month for the first 6 months and then at 3-month intervals. Results Serial sonographic examinations revealed a heterogeneous echo pattern in 78 cysts (93%); a progressive decrease in diameter in 76 cysts (90%); calcification of the cyst wall, cystic contents, or both in 10 cysts (12%); and complete disappearance of 1 cyst (1%) in a patient who had been monitored for over 6 years. Five patients developed urticaria, and 6 developed fever. One patient developed a biliary fistula after the first aspiration attempt. Two patients developed infection of the cyst cavity after PAIR-PD and were successfully treated with oral antibiotics. An anaphylactic reaction developed in 2 patients and was successfully treated with antiallergenic medication. No recurrence of hydatid disease after PAIR or PAIR-PD was observed in any patient over the follow-up period of 72 months (mean, 26 ± 27 months). Conclusions Percutaneous drainage of hydatid cysts is a safe, effective, and reliable treatment. Antiallergenic medication is required before PAIR or PAIR-PD. Both sclerosing agents, hypertonic saline and silver nitrate solutions, gave excellent results. © 2000 John Wiley & Sons, Inc. J Clin Ultrasound 28:469–478, 2000.
