S-plasty for various anal lesions

Ten patients underwent S-plasty between July 1979 and April 1990 for the treatment of various anal conditions. Six patients had giant condyloma acuminata, and there was one patient each with Bowen's disease, verrucous carcinoma, and stricture, and ectropion (Whitehead deformity). Both anatomic and functional results were satisfactory in all patients, and there were no serious complications. S-plasty is the preferred method for the reconstruction of extensive circular denuded anal canal with full-thickness graft of bilateral rotating skin flaps. It is important not only to construct large flaps with a good blood supply, but also to obtain complete hemostasis of the raw surface.
