Results of levatorplasty for anal incontinence.
Since the introduction of the levatorplasty, 44 patients were operated upon for anal incontinence on our service. In 31 patients, a levatorplasty was performed. The selection of the levatorplasty as operative procedure was based on the availability of a functional levator as demonstrated by physical examination, anorectal manometry, and defecography. The 31 patients ranged from infancy to 76 years of age and 30 of them were followed up to 7 years with an average of 3 years. In 18 patients with fecal incontinence following operative procedures for anorectal malformations, satisfactory continence was restored in 8, improvement was found in 6, and 4 patients remain incontinent. In 13 patients with incontinence following operative procedures or trauma, the postoperative results were satisfactory in 9 patients, 2 improved, and 2 failed. The review showed that the levatorplasty was most successful in patients in whom the revised but normally innervated levator replaces a destroyed external sphincter in the presence of an intact internal sphincter. Only one half of all patients with major incontinence following an operative procedure for anorectal malformations had an adequate levator that allowed successful restoration of function. The review showed that the levatorplasty can improve or restore anal continence in a variety of conditions in properly selected patients.
