Primary definitive procedure versus conventional three-staged procedure for the management of low-type anorectal malformation in females: A randomized controlled trial

摘要

Introduction: Females with Krickenbeck low-type anorectal malformations - vestibular fistula (VF) and perineal fistula (PF) - are managed either by a primary definitive or conventional three-staged approach. Ultimate outcome in these children may be affected by wound dehiscence leading to healing by fibrosis. Most of the literature favors one approach over other based on retrospective analysis of their outcomes. Whether a statistically significant difference in wound dehiscence rates between these approaches exists needed to be seen. Materials and Methods: A randomized controlled trial for girls P Results: Of the 64 children randomized, 54 (84%) had VF. Both groups were comparable in demography, clinical profile and age at surgery. The incidence of wound dehiscence (39.4% vs. 18.2%; P = 0.04), immediate postoperative complications (51.5% vs. 12.9%; P = 0.001), and early postoperative complications (42.4% vs. 12.9%; P = 0.01) was significantly higher in Group I as compared to Group II. Six of 13 children (46.2%) with dehiscence in Group I required a diverting colostomy to be made. Conclusions: Females with VF or PF undergoing primary definitive procedure have a significantly higher incidence of wound dehiscence (P = 0.04), immediate (P = 0.001) and early postoperative complications (P = 0.01).
