Adhesion of labia minora in young girls is relatively common in clinic, pediatrics and gynecology outpatient clinics are consulted, mainly in young girls under the age of 5. Most of the pediatricians and gynecologists can make a clear diagnosis and give the correct treatment to achieve ideal results. I. Data and Methods 1. Symptoms and Signs Abnormal urination and difficulty in urination were the main causes. Abnormal urination is mainly manifested as thinning of the urine line, change of the direction of urination, upward, downward, or divergence, or urination without a line. Children usually have a history of vulvovaginitis, manifesting redness and swelling of the vulva, with a lot of secretions. Occasionally, some children scratch with their hands because of pain, and some of them consult the doctor when their parents find abnormalities when cleaning the vulva. Symptoms are the two sides of the labia minora are adhered together, there is a translucent band in the middle, membrane, can not see the urethra and vaginal opening, or adhered to the upper and lower part of a fissure, urine from the fissure discharge. The vulva and anus are red and swollen, and there may be leukorrhea-like discharge or scratch marks. 2.Diagnosis According to the symptoms and signs, it is not difficult to diagnose, inexperienced people can ask experienced gynecologists to consult, not blindly deduce, correct the position of the child, careful examination, clear diagnosis and differential diagnosis. 3, treatment methods Diagnosis is clear that the adhesion separation surgery: manual separation. If the adhesion is light, the first step is to separate the adhesion by manipulation. Children are often uncooperative, parents and assistants can set up the child for forced cystotomy position, 0.5% povidone-iodine cotton ball anti-inflammatory vulvar skin, bupivacaine swabs clamped on the outside of the child, retained for 3min, the operator two thumbs symmetrically in the labia minora on the outer side of the slow outward and gently downward pressure to make the adhesion separation, adhesion of light that will be separated. If the adhesion is relatively tight, it is difficult to separate, you can use local estrogen ointment coated 10~14 days, so that the local epithelial hyperplasia adhesion will be separated by itself, generally do not advocate surgery, due to the trauma caused by the surgery, easy to lead to the local reoccurrence of adhesion. If long-term non-healing can be replaced with antibiotic ointment coating [1]. Probe separation method. Adhesion is more serious, difficult to separate by manipulation and estrogen treatment is not separated, that is, the probe separation method. Because the adhesion time is long, the area is large, only in the clitoris below or the posterior perineum joint has a small hole, so it is appropriate to use the probe separation method. Can be used than the gynecological uterine probe thin stainless steel needle or diameter 2 ~ 3mm steel wire high-temperature autoclaved, from the adhesions inserted, along the translucent band discretionary separation of adhesions, so that the urethral opening and the vaginal opening is completely exposed. If the adhesion area is large, it can be separated in several times, paying attention to the moderation of the operation, so as not to cause excessive damage and re-adhesion. The children were successfully separated by manipulation, and the treatment was natural. 1 week later, the trauma was well healed, the surface was smooth, and there was no re-adhesion, and 1 month later, there was no abnormality, and the result was satisfactory. Discussion 1, etiology of young girls labia minora adhesion is mainly due to young girls vulvovaginitis long-term stimulation and its physiological characteristics are prone to inflammation: imperfect vulvar development, can not cover the urethral orifice and the vaginal vestibule, bacteria are easy to invade. The vaginal environment of infants and young children is different from that of normal people, 2 to 3 weeks after the birth of the newborn, the low level of estrogen from maternal sources, the vaginal epithelium is thin, glycosuria is less, the pH value rises to 6 to 8, Lactobacillus is a non-dominant bacterium, low resistance, susceptible to other bacterial infections, vulvar injuries or pinworm infections can cause inflammation. Foreign body in the vagina, infants and young children curious to place a foreign body in the vagina, resulting in infection, so that the secretion increases, pus and blood and has a bad smell, over time, the formation of ulcers in the vaginal mucosa or inflammation caused by granulation tissue hyperplasia, secretion of long-term stimulation of the vulva caused by the labia minora adhesion. 2.Diagnosis According to the description of the history, clinical manifestations and signs, the diagnosis of young girls labia minora adhesion can generally be clear: most of the children have a history of vulvovaginitis, there are urinary abnormalities, urinary stream is fine, upward, downward or forked or urine is not a line, dribbling, difficult to urinate, scratching the vulva with their hands, physical examination to visual field is sufficient, forced bladder truncation position to see the children on both sides of the labia minora adhesion, the middle of a semi-transparent strip, membrane, can not see the urethral opening. In the forced cystotomy position, there is a translucent band in the middle of the labia minora, which is membranous, and the urethral and vaginal openings cannot be seen, or there is a fissure on the upper and lower part of the adhesion, and the urine is discharged from the fissure. 3, treatment after the diagnosis is clear to give timely and correct treatment, early treatment. The use of manual separation, local infiltration anesthesia, infants and young children with little pain, short treatment time, fast recovery. Probe separation method, be sure to fix the child, forced bladder lithotomy position, the operator should be experienced to operate accurately, moderate strength, gentle movements, so as not to cause collateral damage, intraoperative, postoperative timely and adequate rub antibiotic ointment, wash thoroughly after urination and defecation, in order to prevent the wound from infection or re-adhesion. 4.Prevention of the clear causes of young girls labia minora adhesion, for the prevention of the occurrence of the disease, the development of a solid foundation, active prevention and treatment of infantile vulvovaginitis is very important. The common pathogens of vulvovaginitis in young children are Escherichia coli and Staphylococcus, etc. At present, Neisseria gonorrhoeae and Trichomonas albicans have also become common pathogens. Pathogens are often transmitted indirectly through the hands, clothing, towels, bathtubs, etc. of sick mothers. Young children should try not to wear crotchless pants and use diapers with good ventilation to reduce the chance of infection. Keep the vulva dry, clean, reduce friction, timely treatment of vulvovaginitis, avoid labia minora adhesion.
