One-stage correction of imperforate anus and rectovestibular fistula in girls: Preliminary results

Abstract

Background/purpose: This prospective study was designed to assess the safety, cost effectiveness, and advantages of performing posterior sagittal anorectoplasty without colostomy on girls with imperforate anus and rectovestibular fistula.

Methods: Four girls with imperforate anus and rectovestibular fistula were entered into the study. Chest x-ray, renal ultrasound scan, and lateral fistulogram were done. Rectal pouches were washed through the fistula with NaCl and aqueous povidone-iodine solutions. Peña's posterior sagittal anorectoplasties were done in the prone positions. Cephalosporin and metronidazole were given as perioperative antibiotics.

Results: All patients had intermediate anomalies. There were no other major associated congenital anomalies. Washout through the fistula was easy. There were no particular problems with posterior sagittal anorectoplasty in the prone positions. Two patients had perianal skin excoriations; one had superficial infection of the posterior sagittal wound. Two patients have undergone follow-up for a year. All are having monthly dilatations. All patients pass stool without need of stool softeners or enemas.

Conclusions: This preliminary study shows that it is feasible for girls with imperforate anus and rectovestibular fistula to have safe posterior sagittal anorectoplasty without colostomy. The advantages of one, instead of 3 major operations, are many, especially in developing countries.
