Abstract
Long strictures of the anal canal, extending from the dentate line to the perianal skin, have challenged surgeons for many years. Numerous techniques have been devised to treat anal strictures. A technique to relieve an anal stenosis that involves the entire circumference and the length of the anal canal from the dentate line onto the perianal skin is described. It has two principal advantages: 1) it provides a broad skin flap for the entire length of the involved anal canal; and 2) it provides primary closure of the donor site. In addition, it avoids extensive mobilization of tissue, the flap maintains good blood supply with minimal tension, and there is no small tip prone to necrosis.
