Introduction: Colposcopy is an important diagnostic tool in the evaluation of patients with abnormal pap smears. However, in 10-20% transformation zone (TZ)/squamo-columnar junction is not completely visualized and these patients are deemed to have an incomplete colposcopy examination. Such patients usually require conization, a procedure associated with significant morbidity. Various agents like misoprostol, estrogens and laminaria tents have been used in the past to overcome the non-visualization of TZ.

Aim: The present study was conducted with the aim to compare the efficacy of vaginal versus oral estradiol administration in overcoming incomplete colposcopy.

Materials and Methods: Forty patients with non/partially visualized TZ during colposcopy were recruited for the study. These patients were randomly distributed into two groups: In Group I, 25g estradiol was administered intravaginally daily for seven consecutive days followed by a repeat colposcopy on day 8. In Group II, a seven day course of 25g oral estradiol was followed by a repeat colposcopy on day 8. The efficacy of the two regimens in improving visualization of the TZ on colposcopy and their adverse effect profile was compared.

Results: Vaginal estradiol had an overall efficacy of 70% in improving visualization of the TZ as compared to oral estradiol which was effective in 50% of patients (p-value-0.19). Major adverse effects in both the group of patients were nausea and vaginal discharge with no significant differences among the two groups.

Conclusion: Both vaginal and oral estrogens had comparable efficacy and similar adverse effect profile in improving visualization of the TZ.
