Bleeding from decortication after cervical conization usually lasts about 1-2 weeks and is less than menstrual flow, but may vary somewhat among individuals. The diagnosis of decidualization after cervical conization is made mainly by observing vaginal discharge. After cervical verteotomy, when the vaginal bleeding stops and there is again increased vaginal brown discharge, crusty shedding, sudden vaginal bleeding, etc., consider post-cervical conization debridement, which is usually accompanied by a small amount of vaginal bleeding. If heavy bleeding occurs during debridement, or if significant irregular bleeding persists after 2 weeks of bleeding, abnormalities should be suspected and active medical consultation is recommended. In addition, patients are advised not to have sexual intercourse for 8 weeks after the cervical spinal incision, especially for the first 4 weeks after surgery, to avoid infection of the wound site and bleeding due to forced removal of the scab. At the same time, during the bleeding period, it is necessary to wash the vulva daily and change the sanitary napkin in time.
