Perianal abscess is a common acute onset disease in proctology. If surgery is performed for a perianal abscess, it is recommended that the patient be hospitalized. Hospitalization observation is mainly for the local wound, to prevent recurrence and infection, and to ensure early proper wound dressing and drainage work, laying a good foundation for granulation growth post-surgery. The general hospitalization duration is about one week to ten days. In some cases, where the symptoms are severe or the abscess cavity is large, the hospital stay may extend to 20 days. During hospitalization, it is necessary for a professional proctologist to disinfect and change dressings of the local wound, and it is important to wash with saline water after each bowel movement.
