The most significant sequelae of circumferential hemorrhoidectomy are anal stenosis. Circumferential hemorrhoidectomy is indicated for severe circumferential hemorrhoids and internal hemorrhoids with rectal mucosal prolapse. It has the advantage of removing all the circumferential hemorrhoids in one stage, avoiding secondary surgery, but the disadvantage is that the operation is very invasive. If the wound becomes infected after the operation, it will lead to more serious anal stenosis, and there are many postoperative complications. Currently, this procedure is rarely performed in clinical practice and has been replaced by the pph procedure, which has far fewer postoperative complications. Therefore, it is recommended that patients who have severe circumferential mixed hemorrhoids still perform pph surgery and not circumferential hemorrhoidectomy.
