Continence in patients who undergo posterior rectal flap anorectoplasty.
OBJECTIVE
The authors report the postoperative follow-up results of patients who underwent posterior rectal flap anorectoplasty (PRFA), with emphasis in fecal continence. Variables considered on each patient were sex, presence of fistula, location of the fistula, severity of the defect during the correction, sacral condition, dysraphism, and age at surgery.


METHODS
Continence was rated using the Peña method and defecogram. The authors studied 20 patients (17 boys and three girls).


RESULTS
Postoperatively, normal continence was found in 18 patients. Of the two remaining (boys), one had grade II spotting (sacrum agenesia and uretrobulbar fistula) and the other had grade II staining; this patient had the most severe malformation requiring an abdominoperineal approach. All of the defecograms showed complete emptying of the rectum. No recurrent fistulas occurred.


CONCLUSIONS
The posterior rectal flap anorectoplasty is a new technique that takes into consideration all known factors that contribute to continence. This initial report confirms that this technique results in excellent continence for patients with imperforate anus.
