How long the absorbable thread can fall off when it is exposed depends on whether the patient’s wound is infected and the specific healing situation and other factors for objective analysis. First, if the patient’s wound does not appear red, swollen, painful and other acute infections, the healing condition of the wound is still good. The absorbable thread in the wound is basically completely absorbed, and the exposed absorbable thread can generally fall off by itself in about a week, which will not cause the wound to open. Second, if the patient’s wound healing is poor, localized with fluid and pus, the absorbable line is often not self-absorbing, and it usually takes 2-3 months to fall off on its own. If necessary, thorough debridement and drainage of the incision, removal of necrotic tissue, removal of absorbable threads, and secondary suturing of the wound at a later stage are needed to promote faster wound healing.
