Pediatric patients with recto-vestibular fistula have good prognoses in terms of bowel function when properly treated. Aim & Objective: The study was designed to assess the surgical morbidity of single stage Anterior Sagittal Anorectoplasty (ASARP). Methodology: This prospective study was carried for a period of 26 months. It included a total of 48 female patients (aged 0 - 14 years) with diagnosis of Anorectal Malformations (ARM) with vestibular fistula or perineal ectopic anus. In ASARP, Patient in lithotomy position, the anterior portion of sphincter muscles were cut through a midline perineal skin incision, rectum was separated from the vagina & then rectum was pulled through the center of these muscles. The perineal body was reconstructed and the normal appearance of perineum was achieved. Results: Short-term surgical outcome was satisfactory in all cases. No one needed colostomy. Conclusion: Single-stage ASARP is a good approach in experience hands for ARM with vestibular fistula and perineal ectopic anus in females and thereby complications and time involved in staged procedures including colostomy can be avoided.en-USAnterior sagittal anorectoplastyanorectal malformationsperineal ectopic anusvestibular fistulaArticle
