Лучшие больницы для «Colposcopy» в Дубай, ОАЭ

Colposcopy is a secondary-level gynaecological investigation performed when a primary cervical screening test — such as a liquid-based cytology (LBC) Pap smear or high-risk HPV (hrHPV) co-test — returns an abnormal or unsatisfactory result. Using a colposcope, a binocular magnifying instrument with co-axial illumination (typically 6× to 40× magnification), the clinician applies dilute acetic acid (3–5%) and Lugol's iodine (Schiller's test) to the transformation zone of the cervix to identify acetowhite epithelium, punctation, mosaicism, and atypical vessels — the hallmark colposcopic patterns of cervical intraepithelial neoplasia (CIN). The grading of colposcopic impression follows the International Federation for Cervical Pathology and Colposcopy (IFCPC) 2011 Nomenclature, stratifying findings into normal, minor-change (Grade 1), major-change (Grade 2), and suspicious-for-invasion categories.

• Women with an abnormal Pap smear result: atypical squamous cells of undetermined significance (ASC-US), atypical squamous cells — cannot exclude HSIL (ASC-H), low-grade squamous intraepithelial lesion (LSIL), or high-grade squamous intraepithelial lesion (HSIL)
• Women with a positive hrHPV test (especially HPV 16 or 18) regardless of cytology result, as per risk-based management guidelines (ASCCP 2019)
• Women with unexplained post-coital bleeding, intermenstrual bleeding, or persistent vaginal discharge not explained by infection
• Women with a clinically suspicious-looking cervix on speculum examination (irregular surface, friable tissue, contact bleeding)
• Follow-up surveillance after prior treatment for CIN, VAIN, or cervical cancer

Required Pre-Procedure Diagnostics:

• Recent Pap smear / LBC cytology report and HPV genotyping result (within 12 months)
• Transvaginal ultrasound (TVS) if uterine or adnexal pathology is suspected
• STI screen (Chlamydia, Gonorrhoea, Trichomonas) — active pelvic infection is a relative contraindication
• Beta-hCG (urine or serum pregnancy test) — colposcopy can be performed in pregnancy, but ECC is contraindicated
• Complete blood count (CBC) and coagulation profile (PT/INR, aPTT) if biopsy or excision is anticipated
• +1 more

Colposcopy encompasses both a diagnostic procedure and, where clinically indicated, same-session therapeutic intervention. The following techniques represent the current spectrum of colposcopic practice at advanced gynaecological centres:

1. STANDARD DIAGNOSTIC COLPOSCOPY

Performed under direct colposcopic visualisation using a Leisegang, Zeiss, or equivalent binocular colposcope. Sequential application of 3–5% acetic acid followed by Lugol's iodine allows grading of the transformation zone type (TZ1: fully ectocervical and visible; TZ2: partially endocervical; TZ3: fully endocervical) per IFCFC 2011 criteria. Colposcopically directed punch biopsies (1–4 samples) are taken from the highest-grade areas. ECC is added when TZ3 is present or when cytology-colposcopy discordance exists (cytology HSIL but colposcopy low-grade).

2. DIGITAL VIDEO COLPOSCOPY WITH AI-ASSISTED IMAGE ANALYSIS

PRE-PROCEDURE (Days –7 to –1):

• GAF Healthcare patient coordinator reviews all prior cytology, HPV test results, and imaging reports and shares them with the assigned colposcopist for pre-procedure planning.
• Pelvic infection screen and pregnancy test are completed within 7 days of procedure.
• Patient is advised to schedule the procedure for mid-cycle (days 10–20) to avoid menstrual blood obscuring visualisation — though colposcopy can be performed at any time.
• Avoid intercourse, vaginal douching, and intravaginal medications for 24 hours prior.
• If anticoagulants (warfarin, DOACs) are in use, haematology consultation is arranged 5–7 days in advance for bridging protocol.
• No fasting required (procedure is outpatient under local anaesthetic or without anaesthesia).
