Eleven patients underwent posterior sagittal anorectoplasty(PSARP) as a secondary procedure. Two of them had rectovaginal fistula and another two had rectocutaneous fistula. Six of the rest complained of frequent fecal soiling and the last one had<br>severe anorectal stricture after perineal anoplasty. Five patients had lived with colostomy until the second operations were carried out. The ages at the time of the secondary PSARP were between 7 months and 29 years. Distal colostogram and MRI were<br>taken to evaluate distal colon, position of the rectum and voluntary muscle. All patients had normal sacrum except one who had anorectal stricture. Seven patients, six with fecal incontinence and the other one with rectovaginal fistula had mislocated<br>anorectums. Three patients, two with rectocutaneous fistula, the other one with anorectal stricture, had abdominal approach to obtain enough length of colon for pull-through procedure. With the posterior midsagittal approach, we could manage all the<br>problems, rectovaginal fistulas, rectocutaneous fistulas, strictures and malpositioned rectums, without difficulty. No patients had serious complications except wound infection in one. All patients were satisfied with the results after redo-PSARPs even<br>though normal continence has been achieved in only one patient. Seven patients who had continuous soiling or rectocutaneous fistula, needed no more diapers even though four of them showed fecal staining under stressful condition and the other three<br>showed intermittent fecal leaking less than once a day. The rest three of the patients maintained their continence with support of drugs and/or enemas because of constipation. The PSARP is a popular procedure as a primary operation; however, our results<br>suggested that this procedure also gave us a good opportunity for management of serious complication developed after primary anoplasties.<br>
