Extramammary Paget's disease regularly requires a wide resection of skin, often including the anal tract. When reconstructing the anal tract, simulating natural anatomy by creating the thinnest possible flap is essential to prevent incontinence. We reconstructed the anal and perianal area using a posterior thigh trilobed flap. The lobe to be transposed to the anal duct had a square design and was thinned. The other lobes were used to cover perianal defects and the flap donor site. Using this method, we reconstructed three patients who required large perianal area and anal tract resections. All flaps took well, and after the initial healing process, the patients did not develop lasting incontinence. We conclude that the posterior thigh flap with a thin square wing is useful for reconstruction of the anal tract and perianal area.
派杰氏病通常需要广泛切除皮肤，通常包括肛门。在重建肛门时，通过创建尽可能薄的皮瓣来模拟自然解剖结构对于防止失禁至关重要。我们使用大腿后侧三叶瓣重建肛门和肛周区域。要转移到肛门管的皮瓣为方形设计并变薄。其他皮瓣用于覆盖肛周缺损和皮瓣供区。使用这种方法，我们重建了 3 名需要大面积肛周和肛门管切除的患者。所有皮瓣均良好愈合，在初始愈合过程后，患者未发生持续失禁。我们得出结论，带有薄方形翼的大腿后侧皮瓣对于肛门和肛周区域的重建很有用。
