Posterior sagittal anorectoplasty for adults. A sphincter-saving operation.

We performed posterior sagittal anorectoplasty to treat two adult patients. One patient had an idiopathic stricture extending from the proximal sigmoid colon to the anus. The second patient was born with a high imperforate anus and, following a pull-through procedure as an infant, remained totally incontinent of feces. Both patients now have excellent fecal continence following this operation. The posterior sagittal anorectoplasty may be used to preserve rectal continence in selected adults.
