In clinical practice, external hemorrhoids are not classified by degrees but mainly into skin tag hemorrhoids, varicose vein hemorrhoids, inflammatory hemorrhoids, and thrombosed hemorrhoids. Skin tag hemorrhoids and varicose vein hemorrhoids typically cause sensations of foreign bodies in the anus and feelings of anal prolapse, etc., and conservative medication treatment is generally chosen for these.

However, thrombosed hemorrhoids or inflammatory hemorrhoids can cause significant anal swelling and pain, severely impacting the patient's normal life. For these two types of external hemorrhoids, it is recommended to promptly undergo hemorrhoidectomy, followed by medication treatment to promote healing of the surgical site. Because the surgical site for hemorrhoid operations is located at the anus, it is susceptible to contamination from feces and other secretions, which can easily lead to local infections, bleeding, and swelling. Therefore, it is essential to persist in changing dressings and to maintain smooth bowel movements.
