Thread rejection can be referred to the General Surgery Department or to the department that performed the surgery. Thread rejection is a normal phenomenon, and there is no need to be overly alarmed. Surgery is usually performed with absorbable or silk sutures. Due to the difference in personal constitution, some patients may have rejection of the suture, which usually only needs to be removed or dismantled by the surgeon under standardized operation. Rejection of sutures is a normal phenomenon, which is related to individual constitution. If there is infection at the suture site, you can use some antibiotics or disinfectants, such as mupirocin ointment and iodine povidone etc. externally. If you find that the suture is not absorbed after the surgery and there is thread rejection, you should go to the general surgery clinic of the hospital in a timely manner, under the guidance of the doctor to standardize the treatment, keep clean and prevent infection.
