Twenty five patients with moderate to severe anal stenosis were treated with sliding<br>skin graft during the period of time from April 1987 to March 1996.<br>And a follow-up study was carried out on 18 cases among them. The original causes<br>of the anal stenosis were previous necrotherapy in 14, hemouhoidectomy in 3, and<br>cryotherapy in one. Postoperatively, partial disruption of the suture line developed in 2<br>cases and perianal fistula in one. Long term clinical results were good in 12 cases, fair<br>in 4, and poor in 2. As a result, sliding skin graft is thought to be a simple and<br>effective method for the treatment of moderate to severe anal stenosis.<br>
