title: [Axial computed tomography in anorectal malformations: a pre- and postoperative indication?].
abstract: Ten patients with anorectal malformations were studied by preoperative CT: well developed sphincteric muscular structures (puborectal sling of levator ani, muscular striated complex and external sphincter) were present in six patients. In three patients muscular structures were poorly developed (case 2a with rectovaginal fistula, case 5a with rectocloacal fistula and case 7a with prostatic fistula). In one case with bladder fistula, the sphincteric musculature was not identified at all. Eleven patients were postoperative studied by pelvic CT: Two of 11 cases had a good sphincteric control. The other nine patients were incontinent. In three of the nine incontinent patients, the colon was appropriately place, but puborectal muscle and sphincteric complex were hypoplastic. In the other six cases CT showed a pulled through colon out of the sphincteric structures. Four of them presented major bony sacral abnormalities and/or lesion of the sphincteric muscle structures. The remaining two patients with an evident pulled-through colon out of a normally developed sphincteric region and without sacral anomalies, were selected for a secondary PSARP procedure. In one of these two patients the operation brought about a complete resolution of the fecal incontinence. The pelvic CT is a useful examination in the anorectal malformation for the preoperative prognostic evaluation of continence, while postoperative CT is essential in selecting those incontinent patients who need a secondary PSARP for the treatment of fecal incontinence.
