Every patient will have discharge after perianal abscess surgery, which is a normal phenomenon. Generally, until the incision is completely healed and the skin completely covers the incision, it will be accompanied by discharge, the amount of which will become less and less, and there will be no more discharge when the incision is completely healed. In addition, if the perianal abscess is poorly drained, the internal opening is not cleaned, or the traumatic tissue is not fresh, there will be continuous discharge, and the amount will even increase. This should be considered whether it is caused by surgery or incomplete medication change. If it is caused by incomplete dressing change, clean the wound in time, clean the necrotic tissue in the incision, stuff the oil gauze and keep the drainage open. If it is caused by incomplete surgery, the cause should be identified, and timely re-operation, thorough debridement, and treatment of the internal opening should be performed. The surgical debridement must not leave any dead ends, and the secretions and necrotic tissues should be cleaned thoroughly. If you cannot do it by yourself, it is better to come to the hospital for debridement and medication change by a professional doctor.
