If the anastomotic nail has not fallen out beyond the normal recovery time, you need to go to the hospital in time to have the anastomotic nail removed by a specialized instrument. Generally, the anastomotic nail will fall off by itself in about 2 weeks to 1 month after the surgery, but there may be a small number of patients whose anastomotic nails are embedded in the tissues and cannot fall off by themselves. Therefore, it is necessary to go to the hospital, under the operation of professional doctors, using special instruments, to remove the embedded anastomotic nails in the tissue. Prolonged non-removal of the anastomosis nail may cause tissue infection, so it is important to have regular check-ups after the surgery and pay more attention to whether the anastomosis nail is left behind. The anastomotic nail removal process may be slightly painful, and there may be a small amount of blood seepage from the wound after removal, which is normal. If the anastomosis nail does not fall off, it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor, so as to avoid delaying the condition.
