Feasibility of One-stage Correction for Recto-bulbar Anorectal Malformations
Background: The feasibility of one-stage correction for recto-bulbar anorectal malformations is unclear. We examined the complications and short-term outcomes of one-stage correction for recto-bulbar anorectal malformations in neonates. Methods: We retrospectively examined six neonates who underwent one-stage correction for recto-bulbar anorectal malformations between 2004 and 2011. We reviewed the postoperative complications and functional evaluations-via the Kelly score, Krickenbeck classification, and magnetic resonance imaging. Results: During the study period, nine neonates were diagnosed with recto-bulbar anorectal malformations. Among these, one-stage correction was performed in six patients. The recto-bulbar urethral fistulas were confirmed by urethrography. All cases underwent posterior sagittal anorectoplasty. The average Kelly score was 4.33±1.21. Using the Krickenbeck classification, one child had grade 3 constipation. Grade 3 soiling was not noted. One child had malpositioning of the rectum that was revealed by magnetic resonance imaging. Conclusions: One-stage correction for intermediate imperforate anus is feasible even during the neonatal period.
