Why enlarge the cervical canal
Normal cervical canal tightly closed in order to prevent the ingress into the cavity of the uterus infection. The surface of the mucous membrane of the cervical canal lined by columnar epithelium which produces mucus. She has a porous structure that fills the cervix, forming a kind of tube. The viscosity of mucus and pore size depends on the level of hormones. During ovulation, the viscosity decreases and the pore size increases, it facilitates the passage of sperm. The flow of mucus outward, it is more pronounced on the periphery, it helps "filter" full of sperm. During pregnancy the cervical canal is tightly closed, it changes its color and becomes bluish. Before birth, it expands and can reach up to 10 cm in diameter.
To inspect the cavity of the uterus, the gynecologist uses a technique of hysteroscopy as the most informative for diagnosis and treatment. It allows to detect pathology within the uterus to make a diagnosis, to perform a targeted biopsy or surgical procedure (e.g., abortion). Hysteroscopy is always preceded by a manual study to determine the location of the uterus and its size. Then carried out the expansion of the cervical canal.
How is the expansion of the cervical canal
The expansion of the cervical canal for examination of the uterine cavity is performed as follows. The patient should be on special gynecological chair. The vagina and perineum treated with special disinfectants as before surgery. After manual examination, the doctor exposes the cervix using mirrors. Manipulation begins with the capture of the anterior lip of the cervix with forceps. Then the uterine cavity probing to determine the size and direction. After that consistently expand the cervical canal to 8 mm special tools-dilatatore. This is followed by a hysteroscopy.
If the purpose of expansion of the cervical canal is curettage, the uterine cavity is injected a sharp curette to the bottom of the cavity. Further sequential movements of the tool forward and back spend curettage of the uterus to receive the greatest number of scrapings. After that, the cervix is treated with a special solution. Curettage performed for the termination of dysfunctional uterine bleeding and to remove the maximum number giperplazirovannah and necrotised endometrium for further histological examination. This procedure leads to the cessation of heavy bleeding for a few months.
Advice 2: What is a gynaecological curettage
The curettage is one of the most frequently performed medical procedures in modern obstetrics. It can be done for a variety of reasons, for diagnostic purposes or in the framework of therapeutic interventions. The doctor using special tool removes the superficial layer of the endometrium, i.e. scour it.
In itself, the removal of the mucosa from the inner wall of the uterus is not unusual. In healthy women in productive age this occurs every month and is manifested in the form of menstrual bleeding, when the blood issued out pieces of exfoliated endometrium. But sometimes you need a so-called gynecological curettage, in which the epithelial layer is removed by a doctor using a special tool - a curette.
Most often, the curettage is performed for diagnostic purposes, for example, if a woman in a long time complains of severe bleeding, the cause of which using the ordinary survey cannot be established. The procedure is usually accompanied by examination of the uterine cavity with the help of another gynecological devices known as a hysteroscope. The result of this diagnosis becomes find the cause of bleeding, which can be hormone imbalances, fibroids, polyps, and malignant tumors of the body or of the cervix.
Gynecological curettage for heavy bleeding can also become a kind of therapeutic exercise. For example, in the case of a prolonged menstrual cycle when the endometrium grows so much that to remove it the normal amount of blood released during menstruation is insufficient.
Quite often cleaning is prescribed after the miscarriage, because, despite the severe bleeding, the female body cannot always rid itself overgrown mucosa, the remains of which can lead to an inflammatory process, fraught with negative consequences. Yes, and a regular abortion, produced in the period up to 12 weeks can also be called a gynecological curettage, the only difference is that during the procedure the uterus is removed not only in the endometrium, and the embryo.
Scraping is done usually under General anesthesia. The doctor has the patient on the gynecological chair, handles the external genitalia with disinfectant solution, and then with a special dilator opens the cervix. Curette is a spoon with sharpened edges. With its help, the gynecologist step by step scrapes the mucous membrane. This procedure is simple and takes around 5 to 10 minutes. Contraindications to it, by and large, does not exist, with the exception that the ongoing wanted pregnancy. But do not forget that in any case cleaning is a small, but still surgery, which means it can be inherent risks associated with the supply of anesthesia, for example, allergic reaction to drugs.
