We report on 765 abdominal echinococcal cysts (EC) treated with PAIR (puncture, aspiration, injection, reaspiration), in various Countries. After ultrasound (US)-guided aspiration and parasitological control of the fluid, a scolecide was injected and left inside for 5-30 minutes, then reaspirated. Except for 2 failures (0.26%), reduction and involution of EC were always observed on US follow-up. Anaphylactic shock occurred in 4 cases (0.52%); in one case (0.13%) death ensued. Recurrences were observed in 12 cases (1.57%). Spillage of the fluid in abdominal cavity was observed in 4 cases (0.52%) but because of prophylaxis with albendazole no peritoneal dissemination occurred. Minor complications (fever, rash, biliary fistulas) were observed in 105 cases (13.7%). Follow-up is more than 5 years for 75 cases. PAIR remains a safe and effective therapeutic tool for abdominal EC.
