Colposcopy is a gynecological routine in which a colposcope is used to magnify and illuminate the vulva , vagina and cervix to examine them closely for signs of any abnormal tissue changes .
Colposcopy is a diagnostic procedure that is unremarkably done after an unnatural Pap examination with positive gamy riskHPV ( human papilloma virus ) . It can also be done in an abnormal looking cervix even whenPap smearis negative or when there is an unnatural growth in neck , vagina or vulva or if there is abnormal haemorrhage from the vagina after an intercourse . It is used to detectgenital warts , cervical cancer , vaginal cancerand vulvar Cancer the Crab .
Can a Colposcopy Detect Cancer?
Yes , a colposcopic biopsy can observe cervical , vulvar and vaginal cancer . Generally , colposcopy is perform in a doctor ’s authority . The procedure take about 10 to 20 proceedings . The patient is asked to consist on the examination table with foot support in the same way as is done in pelvic exam or Pap smear . After that a speculum is inserted in the vagina for good visualisation , as it opens up the vagina . A colposcope will be pose outside the vulva for better magnification and illumination of the vagina and the uterine cervix . After examining , acetic window pane solution is used to stain the abnormal cells white , also iodine solution can be used to stain the normal cells browned and the unnatural cells will be better highlighted in the acetowhitening zone of the abnormal cells . A biopsy may or may not be taken establish upon the visual image of the unnatural cadre . If a biopsy is done , then a small component of the unnatural tissue is excised . The biopsied tissue will be sent to laboratory for further testing under a microscope . A biopsy subprogram might do balmy discomfort , cramping pain sensation and light defile later on .
What to Expect After Colposcopic Biopsy?
A colposcopic biopsy might be confident for dysplasia or might be negative . A colposcopic biopsy is normally a definite diagnosis , but one or more of the other diagnostic methods can also be used to essay the extent of the Crab . These let in endocervical curettage ( ECC ) , iteration electrosurgical excision procedure ( LEEP ) , conization , x - ray , CT scan , MRI , PET ( positron emission tomography ) scan , cystoscopy , proctoscopy ( sigmoidoscopy),ultrasoundand laparoscopy .
A colposcopic biopsy results may show :
Cervical Intraepithelial Neoplasia I ( CIN I):This corresponds to modest dysplasia ( abnormal cell ) also known as low degree squamous intraepithelial lesion ( LSIL ) .
Cervical Intraepithelial Neoplasia II ( CIN II):This correspond to moderate dysplasia and is also known as gamy grade squamous intraepithelial wound ( HSIL ) .
Cervical Intraepithelial Neoplasia III ( CIN III):This match to serious dysplasia , carcinoma in situ or adenocarcinoma in situ ( AIS ) , also eff as eminent grade squamous intraepithelial lesion ( HSIL ) .
Colposcopic biopsy is pivotal in identifying and diagnosing cervical precancerous wound as well as carcinoma in situ and plays a major role in cervical cancer prevention and masking . However , it requires other symptomatic testing to further evaluate the counterpane of cervical cancer and its metastasis .
Is Colposcopy Reliable?
Doctors have been relying on colposcopy for the diagnosis and bar of cervical malignant neoplastic disease , but the query is whether it alone is reliable and determinate or not . Many studies have interrogate the inadequacy , non - standardization and subjectivity of traditional colposcopy in assessing and diagnose the precancerous lesions of the cervix . Colposcopy for the most part depends on the acetowhitening zona . If during colposcopy acetowhitening zone is present then the area is biopsied and if the acetowhitening zona is not forge , the biopsy is not opted . There have been several reports , even in encroaching cancer cases when the acetowhitening zone is not formed , and no biopsy has been need . Hence , the detection of the cervical lesions is compromised , delaying the diagnosing and treatment and also increasing the mortality risk .
Thus , to improve the accuracy and sensitiveness of established colposcopy Dynamic Spectral Imaging System ( DYSIS ) digital colposcope is trending to cope for the inaccuracy and subjectivity of its counterpart . The use of DYSIS has been shown to give more exact information and has significantly increased the detection rate of cervical dysplasia and other lesions . adept patient attention is being provided with more classic diagnosis and early detection of cervical cancers .
