It is normal to have secretion in the operated area within 2 weeks after perianal abscess surgery because the operated area itself has exudation, inflammatory reaction and healing through the above process. During this process, there will definitely be pus secretion, which is actually the normal secretion in the operated area. Of course, the specialist will observe the secretion every day when changing medicine, and if it is gradually reduced, the color gradually becomes lighter and lighter, and there is no pus odor, it is normal. If the discharge suddenly becomes more and more yellowish in color and deepens in color about 2 weeks after the operation, it is necessary to consider whether the drainage is not smooth and there may be recurrence after the operation. It is normal to have some purulent discharge at the initial stage, but if the discharge increases after 20 days or changes in color or nature, it is important to seek the judgment of a specialist.
