Purpose: The aim of this study was to describe laparoscopically assisted anorectovaginoplasty (LAARVP) for the repair of selected types of female anorectal malformation.
Methods: Five cases (case 1, rectovaginal fistula with a high rectum; case 2, rectovestibular fistula with double vagina; case 3, rectovestibular fistula with absent vagina; case 4, anovestibular fistula with absent vagina; case 5, cloaca) were reviewed.
Results: Patient 4 had undergone a posterior sagittal anorectoplasty without vaginoplasty at another hospital after misdiagnosis of simple anovestibular fistula. Mean age at LAARVP was 15.4 months. At LAARVP, the fistula was divided in cases 1 through 4 and dissected as low as possible in case 5. In cases 3 and 4, the distal fistula was used to create the neovagina. In cases 1 through 3, the proximal rectum was mobilized and brought through the pelvic floor sphincter muscles using Georgeson's laparoscopically assisted colon pull-through technique through a minimal perineal incision. A posterior sagittal incision was required in cases 4 and 5. However, the initial laparoscopic approach was very helpful in both cases. Currently, all patients are well after a mean follow-up period of 32.2 months. Mean current age is 4.0 years. Patients 1 through 3 are continent, patient 4 is incontinent with soiling, and patient 5 is too young to be evaluated.
Conclusions: LAARVP helps to achieve low dissection of the fistula, gives optimal view of the pelvic organs, provides accurate placement of the anorectal pull-through, and minimizes abdominal perineal scars.
