Anoplasty for anal stricture.

Twelve patients with anatomic anal stricture were treated with C-anoplasty in the past six years. Anal stricture was caused by previous hemorrhoidectomy in ten, fistulectomy in one, and fissurectomy in one. All patients had had conservative treatment from four to 22 years but failed to respond. Eleven patients obtained satisfactory results from C-anoplasty; one required three anal dilatations postoperatively because of restricture. C-anoplasty is advantageous because it extends the pedicle without compromising vascular supplies; suture-line tension can be controlled by extending the incision; and the size of the graft is easily adjustable to anal size.
