Complications of posterior sagittal anorectoplasty.

From 1982 to 1985, 23 patients underwent posterior sagittal anorectoplasty procedures: 12 as primary treatment for congenital anorectal malformations, 9 for treatment of fecal incontinence following a prior pull-through procedure, and 2 for treatment of fecal incontinence following trauma. Six patients (26%) developed seven complications specifically related to the procedure. One patient with a cloacal anomaly had partial dehiscence of the sacroperineal incision following total reconstruction. This resulted in retraction of vaginal and anal openings, which, however, have remained separate and patent. Two patients developed temporary femoral nerve palsies, unilateral in one patient lasting one week, and bilateral in one patient lasting four months. Four patients developed leaks from the suture line of the tailored ectatic rectum, which was pulled through to the perineum. In one male patient, the suture line was placed anteriorly, resulting in a rectourethral fistula, which required a repeat posterior sagittal dissection. One male, who had a redo procedure, developed a posterior diverticulum comparable to a large anal crypt. This was repaired prior to closure of the colostomy. One seven-year-old girl developed multiple rectocutaneous fistulae, which closed with conservative management in five months. One male infant developed a single supralevator rectocutaneous fistula, which closed after rediversion of feces with a colostomy and has remained so after colostomy closure. The majority of the complications encountered were probably preventable if careful attention to certain details of technique had been observed: careful padding of the groin areas when patients are prone, especially in older patients.(ABSTRACT TRUNCATED AT 250 WORDS)
