NON-MALIGNANT STRICTURES: ANAL STENOSIS

Anal stenosis is a rare but serious complication of anorectal surgery . Removal of excess anoderm and mucosa without adequate skin bridges during haemorrhoidectomy can lead to scarring and stricturing. Stenosis can also occur after stapled haemorrhoidopexy and coloanal anastomoses. Other causes include trauma, postradiation fibrosis, tuberculosis and fibrosing skin conditions, e.g. scleroderma. Lymphogranuloma inguinale may cause an inflammatory stricture of the rectum.
