Absorbable sutures are sutured inside the wound and can be absorbed on their own in the subcutaneous or fatty tissue, routinely for about a month. If the absorbable sutures are still not absorbed after a long period of time, the absorbable sutures need to be removed, and if necessary, small incisions should be made in the wound under local anesthesia to intermittently draw out the absorbable sutures. The absorption time of absorbable sutures varies, for example, two months before they can be absorbed. It is normal for them not to be absorbed 20 days or a month after surgery, and they can be absorbed after a while. Some patients will have a rejection reaction to the absorbable suture, the wound will be red and swollen, and even secondary infection, if necessary, the absorbable suture should be removed, and the wound will be re-sutured after the inflammation is controlled.
