Sheep’s intestines are relatively early absorbable sutures. Absorbable sutures can be absorbed in the body as well as subcutaneously and intradermally. Different materials take different amounts of time to absorb, some may absorb in a month, others may take two or three months to fully absorb. In the case of non-absorption of sheepskin, there is a possibility of foreign body rejection under the skin, and there is a possibility of infection of the incision under the skin. In case of foreign body rejection, a piece of sheep’s intestine thread will be spit out from time to time, and the subcutaneous will usually be accompanied by mild redness and swelling, but no pus will flow. In this case, the protruding thread is cut off, or some local anesthesia can be administered subcutaneously to slightly dilate the wound and try to cut more thread. If there is a subcutaneous infection, it means that the threads need to be removed completely. After removing all the threads, the wound will be changed, and when the wound grows back later, the scar may be bigger. If the patient is interested in the aesthetics of the incision, he or she can also go to the plastic surgery department for another reconstructive surgery.
