What Is the Endocervical Canal?

The cervical canal, the cervix is located in the lower part of the uterus, is approximately a cone, and is 2.5 to 3 cm in length.

Cervical canal

Right!

The cervical canal, the cervix is located in the lower part of the uterus, is approximately a cone, 2.5 to 3 cm in length, the upper end is connected to the uterine body, and the lower end is deep into the vagina.

Function 1

Vaginal examination

Function 2

Probe check

Function 3

Angiography

The vault at the top of the vagina divides the cervix into two parts: the part where the cervix protrudes into the vagina is called the cervical vagina, and the part above the vaginal fornix is called the upper part of the cervix. The center of the cervix is a long and slightly flat long-fusal lumen, the upper end of which is connected to the uterine cavity through the inner cervix, and the lower end of the cervix is opened to the vagina through the outer cervix. Inside and outside the mouth is the cervical canal. The non-fertile women at the outer cervix are round, and the women who have given birth through vaginal delivery are horizontally split.

(1) Vaginal examination: Observe the position, shape, external mouth size, secretion volume, traits, and presence of cervical erosion and neoplasm, etc., and pay attention to cervical lifting pain and parauterine tenderness. At the same time for bacteriological examination of cervical mucus. Do a doctor or colposcopy if necessary.

(2) Probe inspection: It is simple and practical to detect the direction and length of the cervical canal and its ratio to the cervix, whether there is stenosis, adhesion and the tightness of the inner cervix. For suspected abnormalities, further radiographic examination should be considered.

(3) Contrast examination: Not only can uterus and fallopian tube lesions be found, but cervical angiography is also very beneficial for studying infertility. When the oil is applied and the imaging device does not affect the development of the neck tube, the length and shape of the neck tube can be displayed well. For cervical neoplasms, congenital malformations, stenosis, adhesions, and uterine flexion can be clearly diagnosed. Cervical canal fibroids, polyps, etc. appear as filling defects with smooth edges on the cervical canal osteotomy film; the edges of the cervical canal adhesion are mostly irregular jagged. The stunted cervix is narrow and long, while the cervical lumen of tuberculosis is relatively wide, and brush-like changes are seen. The length and ratio of the cervical canal and uterine body can also be determined by angiography. Especially for patients with genital dysplasia and cervical stenosis who have failed probe examinations, the angiography is often successful.

Cervix-Treatment

1. Cervical atresia and narrow cervical dysplasia are mainly treated by dilatation.

After menstruation is clean or before ovulation, probe into the uterine cavity with a sterile probe, and then use a cervical dilator to sequentially expand from No. 3 to No. 7. Congenital cervical dysplasia can be treated with artificial cycles at the same time, or high-dose progestin can be used as a false pregnancy therapy. Drainage tubes are placed in the cervix after congenital cervical adhesion or stenosis dilatation to prevent re-adhesion.

2. Cervical abnormalities There is no good treatment for this disease. Try the following:

Raise the hips after intercourse: Place two pillows on the woman's hips during or after sexual intercourse, so that the woman has a low head and high hips, so that semen can accumulate as much as possible in the posterior fornix, which relatively increases the level of semen, which is beneficial to the cervix Soak in semen;

Prone after intercourse: The purpose of this method is to promote the accumulation of semen in the anterior vaginal fornix after intercourse, so that the upturned cervix can be easily soaked in semen;

When the above methods are not effective, the artificial insemination method can be used.
