Reason: Symptoms caused by foreign body staying in vagina for a long time: Parents found that the girl's leucorrhea increased without reason, showing signs of infection, pain or bleeding. Xiaolin, an innocent and lively 7-year-old girl, has been bleeding without reason for more than two years, so she should seek medical treatment as soon as possible. Her parents took her to the hospital many times and treated her for vaginitis, but she never recovered. Recently, in Guangdong Maternal and Child Health Hospital, the doctor found that her strange disease was caused by a crayon sleeve stuffed into her vagina! According to reports, two years ago, my mother found a lot of yellowish secretions on Kobayashi's underwear, which had an odor and later bloody secretions. In the past two years, my mother took her to many hospitals across the country, all of which were treated according to vaginitis, but it didn't work at all. Not long ago, my parents took Xiaolin to Guangdong Maternal and Child Health Hospital, and Deputy Chief Physician He Xiukui gave her a B-ultrasound. It turns out that there seems to be a foreign body at the junction of her cervix and vagina. The doctor asked again and again, but Kobayashi denied that he had stuffed anything into his vagina. Is it vaginitis, vaginal foreign body or tumor? With the consent of Kobayashi's parents, the doctor gave her a non-invasive vaginal peep under anesthesia, and finally found the crayon set of the culprit! Because it has been inserted for too long, the crayon sleeve has stuck to the vagina and invaded the posterior vaginal wall near the rectal wall. Sure enough, Kobayashi's symptoms disappeared quickly after taking out the foreign body. Analysis of foreign body tamponade is mostly due to ignorance and curiosity. It is estimated that because the little girl is young, she is afraid of being blamed by her parents and dare not admit to stuffing foreign bodies into her vagina. Ping, director of gynecology department of Guangdong Maternal and Child Health Hospital, said that there are many people like Xiaolin who are admitted to hospital because of vaginal foreign bodies. There was once a girl of 12 years old who, out of curiosity, stuffed a clothespin in her vagina. Foreign bodies in young girls' vaginas are a series of symptoms caused by girls' ignorance, curiosity or trying to relieve vaginal itching by themselves or other children. Luo Xiping pointed out that these girls may have complained to their mothers about vaginal itching at ordinary times, but they didn't pay attention. Foreign bodies staying in vagina for a long time will cause girls' urogenital fistula, vaginal ulcer, pelvic abscess, calculus, vaginal adhesion and cervical adhesion, which will lead to poor menstrual drainage and dysmenorrhea in the future, which will easily lead to misdiagnosis and bring great pain to patients' body and mind. The expert explained that the vagina is an elastic muscle lumen, the upper end is wider than the lower end, and there are many transverse folds in the vaginal mucosa, so the front and rear walls are very close at ordinary times, and it is difficult for foreign bodies to fall off themselves once they enter the vagina. Moreover, the vaginal mucosa is very delicate, and the surface of foreign bodies is generally rough, which can easily lead to vaginal mucosa and even cervical injury. In addition, the front of the vagina is adjacent to the bladder and the back is close to the rectum. Once a foreign body is accidentally taken, it is easy to hurt these organs. Therefore, when a foreign body is found to stay in the vagina for too long, ask a doctor to help you take it out. For gynecologists, Luo Xiping specially reminded that young girls with leucorrhea and vague medical history should think of the possibility of vaginal foreign bodies. Especially those who have not improved according to the treatment of inflammation should be paid more attention to, and we can't completely believe the history of vaginal foreign bodies denied by patients and make a hasty diagnosis and treatment. It is suggested that girls should be educated on health knowledge as soon as possible. Luo Xiping suggested that parents should have correct health awareness and strengthen health guidance for young girls. In addition, let young girls wear open-backed pants, wash vulva frequently and keep vulva clean. Underwear should be changed frequently, washed separately and dried. To educate children to learn the correct wiping action after defecation as soon as possible, it is best to set up a device for cleaning vulva for young girls. In public places, we should try to avoid letting girls take a bath to prevent vaginal infection.
