Surgery for perianal abscess is mainly incision and drainage, and after surgery, it is necessary to maintain smooth drainage and local cleanliness, and at the same time with medication and dietary interventions, which can promote recovery. For perianal abscess, no matter whether there is an abscess or not, once the diagnosis is confirmed, it is necessary to carry out timely surgical drainage intervention. If the perianal abscess is not drained in time, it will spread to the surrounding interstitial space, which in turn will cause infection of the surrounding tissues and the whole body. After surgery, regular dressing changes are needed to keep the drainage open; erythromycin ointment and other drugs can be used to prevent local infection. In principle, patients with uncomplicated perianal abscesses in good physical condition are not recommended to use antibiotics routinely after performing abscess incision and drainage; for perianal abscesses accompanied by cellulitis, systemic diseases, systemic infections, cardiac valve disease, diabetes mellitus, immunosuppression, etc., it is recommended to use antibiotic treatment, including drugs such as cefadroxil. On the basis of the use of drugs, it is recommended to eat a light diet, a comprehensive intake of various types of food, but care needs to be taken to avoid alcohol, smoking, as well as the consumption of spicy food. These medications should be used under the supervision of a clinician.
