Input: We found no randomised clinical trials comparing PAIR versus no or sham intervention. We identified only two randomised clinical trials, one comparing PAIR versus surgical treatment (n = 50 participants) and the other comparing PAIR (with or without albendazole) versus albendazole alone (n = 30 participants). Both trials were graded as 'adequate' for allocation concealment; however, generation of allocation sequence and blinding methods were 'unclear' in both. Compared to surgery, PAIR plus albendazole obtained similar cyst disappearance and mean cyst diameter with fewer adverse events (32% versus 84%, P < 0.001) and fewer days in hospital (mean + SD) ( 4.2 + 1.5 versus 12.7 + 6.5 days, P < 0.001). Compared to albendazole, PAIR with or without albendazole obtained significantly more (P < 0.01) cyst reduction and symptomatic relief. PAIR seems promising, but there is insufficient evidence to support or refute PAIR with or without benzimidazole coverage for treating patients with uncomplicated hepatic hydatid cyst. Further well-designed randomised clinical trials are necessary to address the topic.
Output:

Two randomised clinical trials on the puncture, aspiration, injection, and re-aspiration method for patients with uncomplicated hepatic hydatid cyst were identified. One trial compared puncture, aspiration, injection, and re-aspiration with surgical treatment. The other trial compared puncture, aspiration, injection, and re-aspiration with or without albendazole with albendazole alone. Both trials had high risk of bias. The number of participants enrolled and the follow-up duration are insufficient for a definite conclusion to be drawn. In general, there is insufficient evidence to support or refute the puncture, aspiration, injection, and re-aspiration method with or without benzimidazole coverage for patients with uncomplicated hepatic hydatid cyst.
