This solution looks like mustard and turns black when exposed to blood.After the procedure this material will be expelled naturally: patients can expect to have a thin coffee-ground like discharge for up to several days after the procedure.Low magnification (2× to 6×) may be used to obtain a general impression of the surface architecture.
The main goal of colposcopy is to prevent cervical cancer by detecting precancerous lesions early and treating them.
The procedure was developed by the German physician Hans Hinselmann, with help from Eduard Wirths.
After a complete examination, the colposcopist determines the areas with the highest degree of visible abnormality and may obtain biopsies from these areas using a long biopsy instrument, such as a punch forceps, Spira Brush CX or Soft Biopsy.
Most doctors and patients consider anesthesia unnecessary; however, some colposcopists now recommend and use a topical anesthetic such as lidocaine or a cervical block to decrease patient discomfort, particularly if many biopsy samples are taken.
Colposcopy with biopsy does not cause infertility or subfertility.
Adequate follow-up is critical to the success of this procedure.The transformation zone, at the opening of the cervix into the vagina, is the area where most abnormal cell changes occur Many premalignant lesions and malignant lesions in these areas have discernible characteristics which can be detected through the examination.It is done using a colposcope, which provides an enlarged view of the areas, allowing the colposcopist to visually distinguish normal from abnormal appearing tissue and take directed biopsies for further pathological examination.Three percent acetic acid is applied to the cervix using cotton swabs.Areas of acetowhiteness correlate with higher nuclear density.A colposcope is used to identify visible clues suggestive of abnormal tissue.
