In this article we explain what is colposcopy, as it is made, what are the indications and which are the possible complications of this examination.

What is colposcopy?

Colposcopy is a word of Greek origin, which can be translated as "viewing the vagina" or "visually examine the vagina". Colposcopy is actually a test that allows the doctor to examine not only the vagina but also the vulva (external part of the female genitals) and the cervix, much more thoroughly than in the common gynecological exam, which is done the naked eye.

Despite its name suggest some resemblance to more invasive tests such as colonoscopy or endoscopy in colposcopy there is no introduction of any device in the vagina of the patient. The colposcope is a device that looks more like a camera or binoculars, as you can see in the picture beside. There are at any time contact the colposcope with the genital region, this always getting about 30 cm away from the patient.

The advantage of colposcopy in relation to the common gynecological examination is that it be able to properly illuminate the vaginal canal and allow the gynecologist can view the region through magnifying lens, allowing lesions ID in the vagina mucosa and colon uterus that the naked eye can not perceive. The colposcope also allows the gynecologist to use color filters as a green or blue light to highlight changes in vascularization in the cervical region.

What good is colposcopy?

Colposcopy is an exam which serves to complement the common gynecological examination usually is indicated when the gynecologist finds necessary a more detailed assessment of the genital tract. In general, both situations indicate means of colposcopy, when the examination of the Pap smear shows some alteration suggestive of premalignant lesion or when during common gynecological examination gynecologist recognize any suspicious lesion in the lining of the vagina or cervix. In both cases, colposcopy is used so that the gynecologist can make a biopsy of the suspicious region.

How is made colposcopy?

Colposcopy does not differ much from the common gynecological examination. The patient lies down on the table with legs spread and the gynecologist introduces the speculum, also known as duck-billed in the vagina to view the inside. So far it's all the same as the patient is accustomed. With the aid of the colposcope, which as we have said often be about 30 cm away from the vulva, the doctor makes a careful assessment of the entire mucosa of the vagina and cervix. In general, one or more of the vagina mucosa biopsies and cervical are performed.

If the doctor can detect the colposcope any suspicious lesion, it will perform a biopsy of this lesion. If no obvious lesions, the gynecologist can use a colorant to facilitate identification of tissue to changes in its cells. The two most used techniques are the Schiller test which uses an iodine-based solution or test acetic acid, which as the name implies, uses a solution of acetic acid. If there are changes at the cellular level, with these dyes they become more apparent, helping the gynecologist to choose which areas of the cervix that should be biopsied.

If the last pap smear from the patient already has more than 6 weeks a new curettage of the cervix can be performed for the sample to be sent along with the biopsy material.

The complete examination lasts between 15-20 minutes and is painless. Some patients experience some discomfort at the time of passage of the speculum or during the biopsy, but in general, it's no big deal. No need anesthesia or sedation to perform colposcopy. Any spatial preparation for the exam is also not necessary.

Contraindications and precautions related to the realization of colposcopy

There is no absolute contraindication to performing colposcopy. However, care must be observed for the performance of colposcopy is optimized.

Therefore, it is suggested the treatment of any gynecological infection prior to the examination.
