Perineal ultrasound in infants with anteriorly displaced anus: A new decision-making tool for the surgeon?

AbstractBackground Anteriorly displaced anus (ADA) is defined as anterior displacement of the toward perineum. Early radiologic characterization a crucial step in guiding first-line management. Objective The objective this study was to assess urethra-to-anus distance (UAD) on perineal ultrasound female infants under age 3 months with anteriorly and retrospectively determine cut-off guide indications for surgery. Materials methods Perineal performed prospectively determination UAD, during screening congenital hip dislocation. Determinations UAD pelvic MRI were girls between 2011 2018. Results 230 patients included, whom 173 control group, 52 examinations 5 vestibular anus. mean was: 22.9 mm (±1.7) healthy infants, 21.4 (±2.4) non-operated ADA, 17.5 (±1.8) operated 10.8 (±1.3) anorectal malformation (ARM). A statistically significant difference observed group ARM (p = 0.0001) ADA 0.0001). over 25.5 (±4.1) 26 (±3) ADA. Conclusion less than 17 appears be malformations.
