Colposcopy is a vital diagnostic procedure that plays a pivotal role in women's health care, particularly in the early detection and prevention of cervical cancer. This procedure involves using a specialized instrument known as a colposcope to examine the cervix, vagina, and vulva closely. By providing a magnified view of these areas, colposcopy enables healthcare professionals to identify and evaluate abnormalities that may not be visible to the naked eye. Directed biopsies are often performed as part of the procedure. Whether as a follow-up to an abnormal Pap smear, in response to high-risk human papillomavirus (HPV) results, or for assessing suspicious cervical appearances, colposcopy plays a crucial role in determining the appropriate course of action to safeguard women's health. This activity outlines the key aspects of the colposcopic procedure along with its significance in clinical practice. It also reviews the role of the interprofessional team in enhancing patient-centered care and ultimately reducing the burden of cervical cancer. Objectives: Identify the indications for colposcopy. Accurately assess and interpret colposcopy findings and effectively communicate the results to patients, providing clear explanations of findings and potential treatment options. Apply appropriate biopsy techniques during colposcopy to obtain representative tissue samples for histological analysis and understand potential complications of colposcopy. Collaborate with interprofessional team members, including gynecologists, oncologists, and primary care providers to improve care coordination and communication with patients needing a colposcopy.

Colposcopy is a diagnostic procedure in which a lighted magnifying instrument called a colposcope is used to examine the cervix, vagina, and vulva. Hans Hinselmen of Germany first described colposcopy in 1925 as a screening tool for cervical cancer. The procedure is performed to evaluate patients with an abnormal Papanicolaou (Pap) test, those who test positive for high-risk human papillomavirus (HPV) DNA, or those with a suspicious appearing cervix, even if screening for dysplasia is negative. It may also be performed as a posttreatment follow-up of cervical intraepithelial neoplasia (CIN) and invasive carcinoma. Although colposcopy is practiced by many clinicians (including advanced practice providers, primary care providers, gynecologists, gynecological oncologists, and others), standardization of the procedural process, necessary training, and continued development and maintenance of colposcopic skills are generally poor. It is also well-documented that colposcopy has significant interperformer variability and poor reliability. In 2017, the American Society for Colposcopy and Cervical Pathology (ASCCP) published colposcopy standards to address these and other concerns.[1] The standardization of terminology was established to simplify and ensure a comprehensive colposcopic exam was performed at every encounter.[2]

Colposcopy complications are most often related to an obscured visual field, severe atrophy, or scarring present. Procedural risks are low, including significant bleeding, infection, and long-term morbidity. There is potential harm in the performance of colposcopy by an unskilled clinician.[14] Anxiety and patient discomfort associated with the procedure can be significant and should not be underestimated. It can be challenging to ascertain if patients' negative feelings about colposcopy are related to the idea of HPV infection or the procedure itself. Professional training and continued experience in colposcopy are necessary for competency. The false-negative rate (missed high-grade squamous intraepithelial/invasive cancer) for colposcopy ranges from 13% to 69%.[15][16] Today, there are improved screening tests with cytology, molecular testing for HPV, and risk-based assessments. Therefore, there is less need for diagnostic testing with colposcopy, which creates less opportunity for ongoing training and experience for newly trained clinicians. This fuels an even greater need for experienced, skilled colposcopists. Even after a negative colposcopic examination, studies have reported subsequent high-grade disease. In a large trial for low-grade abnormalities, the sensitivity of initial colposcopy to detect high-grade disease in the subsequent 2 years was only 53%.[17]  Studies have shown a low level of agreement between the colposcopic impression of disease and final histology.[18][19] The use of multiple biopsies increases the accuracy of colposcopic diagnoses.[20] Endocervical evaluation with a curette or brush may also be helpful.[21] These studies highlight the need for continued observation based on the personalized risk of cytology, HPV testing, and past history.

Sources of Error in Colposcopy Every colposcopic image reflects a specific tissue pattern resulting from the interaction of surface epithelium and stroma. Misinterpretation of patterns is the most common error in colposcopy. A flat, mild acetowhite grade 1 lesion is more likely to be overdiagnosed as these findings mimic immature or active metaplastic epithelium in young women, regenerative epithelium, subclinical HPV infection, and congenital transformation zone. If in doubt, such lesions must be biopsied. Colposcopy should be avoided during the regenerative period of epithelium following CO2 laser ablation, cryosurgery, or trauma. Another common error is making a diagnosis without completely visualizing the cervix in cases where it is obscured by an endocervical polyp or large retention cyst, or there is a stenosed internal os, and in cases of incomplete visibility of the SCJ. Errors may occur in association with pregnancy due to physiological and morphological changes. Vasodilatation and congestion during pregnancy produce accentuated colposcopic patterns with more pronounced mosaics and punctations and enhanced acetic acid effect, which may mimic paraneoplastic lesions. These findings may be minimized by using a large speculum covered with a condom, quadrant-wise interpretation, and remembering that colposcopic changes in pregnancy are 1 grade higher than those in the nonpregnant population. Colposcopic biopsy and the use of an endocervical brush for cytology are safe if indicated during pregnancy, while endocervical curettage is contraindicated.

Colposcopy can be difficult in postmenopausal women. An unsatisfactory colposcopy occurs in 25% of postmenopausal women due to the incomplete visibility of the SCJ and vaginal atrophy. Prior to colposcopy, it may be advisable to recommend these patients use vaginal estrogen to enhance the likelihood of achieving a satisfactory colposcopic examination.

Colposcopy is necessary to prevent cervical cancer from developing, but colposcopic expertise is not commonplace. Health professionals involved in colposcopy, including physicians, nurses, and pharmacists, must possess specialized skills. In the US, colposcopic services are delivered in diverse practice settings, including academic and nonacademic referral settings, primary care environments in urban and rural communities, and clinics funded by private and public resources.[23] Multiple types of clinical professionals can master this procedure. The training of various clinicians should be encouraged and ongoing. Developing a standardized approach to colposcopy is vital. Clinicians should adhere to recommended standardization and documentation of the procedure to improve patient care. Establishing clear protocols, guidelines, and clinical pathways ensures a consistent patient evaluation and management strategy. Future technological enhancement may continue to improve the reliability and validity of the colposcopic results. All team members share the responsibility for patient safety and well-being. Healthcare professionals must collaborate to ensure seamless transitions and a comprehensive care plan for patients with abnormal findings. Enhancing patient-centered care in colposcopy involves honing skills, developing a clear strategy, fostering interprofessional communication, and coordinating care effectively. By prioritizing these aspects, healthcare professionals involved with colposcopy procedures can improve patient safety, outcomes, and overall team performance.
