Transfistula anorectoplasty on adult female anorectal malformation

Abstract Introduction Female anorectal malformation (ARM) is correctable congenital defects. Delayed presentation of patients with anorectal malformation is uncommon. However, presentation beyond teenage years is not commonplace. We describe a case of ARM with rectovestibular fistula and anal atresia. Presentation of case A 31 years old woman with chief complaint of small vaginal introitus. Gynecology examination showed urethra, labia majora, labia minora, and small vaginal introitus. Vaginal length was 6 cm. There was no anal canal. The patient underwent transfistula anorectoplasty and modified Fenton procedure. Discussion The important step of transfistula anorectoplasty (TFARP) procedure is the placement of neoanus in the center of external spinchter to provide continence. The absence of skin incision in anterior and posterior to the neoanus provide good cosmetic result. Compared to PSARP procedure, TFARP procedure has advantage which is the absence of separation of the skin in the midline buttock, the levator muscle, and the external spinchter complex. This lead to optimal fecal continence. In our experience, TFARP is a safe and effective procedure. Daily vaginal dilation in postoperative period is unnecessary. This technique also give good cosmetic result with optimal fecal continence and sexual function. Conclusion Transfistula anorectoplasty procedure for ARM give give good cosmetic result and optimal fecal continence and sexual function. Highlights
