Anoplasty is a procedure for the lengthening of anal circumference of anal stenosis<br>whereby perianal skin flap is moved for cover a defect in the anal canal. Anal stenosis<br>usually results from a operative procedure for anus, especially after surgery for<br>hemorrhoid, perianal fistula and injection therapy for anal disease. Principles of surgical<br>treatment for anal stenosis is focused on the lengthening of anal circumference and<br>reducing internal sphincter tone.<br>However, the degree and associated disease of the stenosis should be considered in<br>making choice of a procedure. Although many procedures have been known, anoplasty<br>using rotation flap is widely applied for the stenosis owing to its wide flap base, good<br>blood supply, less contracture of operative wound.<br>Here we reviewed a series of 12 patients who underwent anoplasty using C-flap as a<br>rotation flap for the treatment of anal stenosis followed by hemorrhoidectomy and<br>injection therapy, and we have been experienced 12 cases from Jul 1985 to Sep 1991 at<br>the department of General Surgery, Ewha Womans University Hospital.<br>The results were good; flap survived completely in 11 patients(92%) and these 11<br>patients have no restenosis and no functional disorder. Only 1 perianal fistula<br>was<br>developed. That's only one complication.<br>
