5 , 12 , 13 In recent years, there has been an increasing trend to use US-guided hydrostatic enema reduction. 14 Two recent studies demonstrated similar safety and efficacy between fluoroscopy-guided air enema reduction and US-guided hydrostatic enema reduction. 15 , 16 A study from China showed a higher success rate of US-guided hydrostatic reduction versus fluoroscopy-guided pneumatic reduction (statistical significance, P = 0.015). 5 Compared with fluoroscopy-guided air enema, US-guided hydrostatic enema has the advantage that it is completely free of radiation.
