Because when the tissue is broken and bleeding, the coagulation mechanism will be activated to quickly achieve the purpose of hemostasis, and the cervical laceration can soon recover on its own. 2. The fissure is relatively deep and large: if the cervical fissure is relatively deep and large, and the fissure to the cervical muscle layer, often can not be repaired on its own, and need to be sutured to achieve the purpose of stopping the bleeding.
