Sliding V-Y Perineal Island Flaps for Large Perianal Defects

Abstract
A large perianal defect resulting from resection of Bowen's disease was reconstructed with a pair of sliding V–Y perineal flaps. The anatomical basis of the flaps is described, based on the inferior rectal vessels as fasciocutaneous units. Both continence and sensibility are preserved with the procedure.
