Colposcopy Procedure – Purpose and Results

Key Points about Colposcopy

  • Colposcopy is a gynecological procedure that offers a magnified and illuminated view of the vulva, vaginal walls, and uterine cervix.
  • It is commonly performed to assess abnormalities in the cervix, often identified through an abnormal Pap smear result or visibly irregular cervix during a Pap smear.
  • Special tests during colposcopy include acetic acid wash, color filter usage, and tissue sampling (biopsy).
  • Cervical abnormalities, ranging from mild to severe dysplasia and cancer, are evaluated, and treatment options depend on the severity determined by colposcopy biopsy results.
  • Treatment procedures for cervical abnormalities, such as cryocautery, carbon dioxide laser, loop electrosurgical excision procedure (LEEP), cold knife conization, and hysterectomy, are generally safe and can be performed in a doctor’s office.

Understanding Colposcopy

Colposcopy is a gynecological procedure that involves magnifying and illuminating the vulva, vaginal walls, and uterine cervix to identify and examine any abnormalities. It is often performed in response to an abnormal Pap smear result or when the clinician observes a visibly irregular cervix during Pap smear collection. Colposcopy involves special tests, including acetic acid wash, color filters, and tissue sampling (biopsy), to assess cervical health.

Why is Colposcopy Done?

Colposcopy is typically conducted in two scenarios: to investigate an abnormal Pap smear result or when the cervix appears abnormal during Pap smear collection, even with a normal Pap result. The primary goal is to determine the cause of the abnormalities and facilitate appropriate treatment.

Colposcopy Procedure

A colposcope, resembling binoculars, is utilized in the procedure, equipped with magnification lenses and color filters. The vulva and vagina are examined for genital warts or growths, followed by a Pap smear. The cervix is inspected, and special tests are conducted. Colposcopy is generally safe, with minimal complications, such as vaginal spotting of blood.

Special Tests During Colposcopy

  1. Acetic Acid Wash:
  • The cervix is washed with a diluted acetic acid solution (3-5%) to enhance visibility and highlight abnormal areas.
  • Acetowhite lesions may appear, aiding in the identification of abnormalities.
  1. Color Filters:
  • Color filters assist in examining tiny blood vessels (capillaries) near the squamocolumnar junction.
  • Abnormal capillaries may appear as red spots or produce specific patterns based on the severity of cervical disease.
  1. Biopsy of the Cervix:
  • Tissue sampling (biopsy) is conducted on abnormal areas identified during colposcopy.
  • Endocervical curettage, sampling the tissues within the endocervical canal, is often performed as part of the biopsy.

Treatment Options Based on Colposcopy Results

  • Destruction (Ablation) Procedures:
  • Carbon dioxide laser photoablation and cryocautery are used to destroy abnormal areas.
  • These procedures are generally safe and can be performed in the doctor’s office.
  • Removal (Resection) Procedures:
  • Loop electrosurgical excision procedure (LEEP), cold knife conization, and hysterectomy involve the removal of abnormal areas.
  • LEEP is the most common treatment for precancerous lesions, providing intact tissue samples for analysis.
  • Hysterectomy is reserved for most cases of invasive cervical cancer.
  • Complications and Considerations:
  • Complications from these treatments are generally rare, with minor issues such as bleeding and cervical narrowing.
  • Procedures like carbon dioxide laser and cryocautery are safe for milder dysplasia but not suitable for advanced cervical disease.
  • Hysterectomy is utilized in cases of severe dysplasia, recurrent dysplasia, or invasive cervical cancer.

In conclusion, colposcopy plays a crucial role in diagnosing and evaluating cervical abnormalities, guiding appropriate treatment decisions tailored to the severity of the condition. The procedure and subsequent treatments are generally safe and can be conducted in a doctor’s office, ensuring effective management of cervical health.
