Perianal abscess is a relatively common surgical anorectal disease in clinical practice, and patients with perianal abscess can apply topical creams for early mild cases. For example, the commonly used creams in clinical practice are Ma Yinglong hemorrhoid suppositories and anti-inflammatory erythromycin ointment, as well as Bactrim ointment. All of these drugs can reduce the degree of perianal abscess infection and avoid surgical treatment for mild or minor perianal abscesses. For some perianal abscesses that have formed larger pus cavities or are febrile and the abscess continues to expand, it is not suitable to apply topical ointments for the time being, so you can apply depurative ointment and anti-inflammatory ointment after surgical incision and drainage. These drugs can accelerate the tissue absorption of perianal abscesses and promote early healing, which is more beneficial for patients with perianal abscesses.
