Abstract：

Mixed hemorrhoid is a common disease in anorectal department, so far, one of the most widely used surgical methods is external dissection and internal ligation. The traditional operation is effective, but postoperative complications such as traumatic edge edema, pain and anal stenosis often occur. In recent years, with the deepening of the understanding of the pathogenesis and anatomy and physiology of hemorrhoids, a wide variety of improved surgical methods have been derived from the external dissection and internal ligation in clinical practice, which reduces the severity of postoperative complications of traditional external dissection and internal ligation. By referring to the domestic literature in the past 5 years, the following review is made on the incision design of external hemorrhoids in various improved surgical methods based on external dissection and internal ligation, aiming to further analyze the incision design strategy of external dissection and internal ligation in clinical treatment of mixed hemorrhoids, and provide  practical reference for medical practice.
