The rectus abdominis muscle does not usually split after suturing, but strenuous exercise before the patient recovers may cause a tear in the rectus abdominis muscle. A separated rectus abdominis muscle can usually be repaired by either minimally invasive surgery or traditional surgery. Minimally invasive surgery usually requires no sutures, while traditional surgery requires the separated rectus abdominis muscle to be repaired by placing sutures against it. Typically after surgery, the wound area heals on its own as the cells grow and does not usually split open. Strenuous exercise or coughing before recovery may cause the suture line to split, causing the rectus abdominis muscle to split after the suture is closed, so patients must take good care of the wound and avoid strenuous exercise. Ensure that the affected area is hygienic and does not become infected or inflamed. If the wound does not heal for a long time after suture surgery, the rectus abdominis muscle should seek medical treatment in time.
