Objective:To investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.
