Abstract
Recently, anorectal anomalies has been greatly improved on the therapeutic results. One of the important factors is, however, the anal pasty having the favorable evacuating functions. We have attempted to reduce the complications such as the anal stenosis and the prolapse caused by the anastomosis between the perineal skin and the bottom end of rectum. We have performed the two flap anoplasty using the V flap and the perineal flap, and good rsults were obtained. The position of anus was confirmed by EMG preoperatively. The center of the anus was incised as a position of the central of the V flap, and the perineal flap was formed at the lateral anterior side. The vascular pedicle from posterior side was included. The hight of the V flap is same with those of lateral axis of the perineal flap. The vascular pedicle of the perineal flap is the cutaneous branch of the inferior rectal artery. It's supply has sufficient enough for filling the anal canal, whihc can be easily confirmed during the operation. Also, the inferior rectal branch of the pudendal nerve covers the anal canal. Flap has a suficient sensations as neurovascular flap. Eventually, we could obtain the satisfactory results with two flap plasty functionally and morphologically.
