Abstract
Anal stenosis is the result of loss of anoderm with scarring and fibrosis, and typically occurs after anorectal procedures in adults, and after pull-through procedures in children. Anal stenosis is classified by severity, location, and extent of the stenosis. Conservative measures with stool softeners/bulking agents and anal dilation may relieve symptoms in some patients with mild disease. For those with more severe stenosis, operative treatment is indicated, and a variety of procedures are available to the surgeon. Sliding, island, and rotational flaps are well described and are typically the first line surgical option. For those with very short stenoses, such after anastomoses or stapled hemorrhoidopexy, lesser procedures such as stricturotomy and stricturoplasty may have some role in treatment. In children, dilation is the first line treatment option, followed by surgical intervention if dilation fails. Determining the degree and extent of stenosis should guide the surgeon to individualize treatment for each patient with anal stenosis.
