    Abstract:
    OBJECTIVE: To explore the feasibility and safety of transvaginal external fascia trachelectomy to conservatively treat patients with stage Ia1 squamous carcinoma of the uterine cervix (SCC) and cervical intraepithelial neoplasia (CIN) III, who are not suitable to take cold knife conization (CKC). METHODS: From July 2002 to September 2010, those patients who had a strong desire to preserve the uterus or fertility but also are confronted with following situations received transvaginal external fascia trachelectomy: CIN III with large area lesion (colposcopically observed lesion area was larger than 3/4 of the cervix), or patients with CIN II-III suffered recurrence or had persistent lesion or positive margin after CKC or LEEP, or patients with CIN II-III upgraded into stage Ia1 SCC through LEEP and pathological confirmation (except for those with lymphovascular space invasion), or CIN III patients complicated with upper vaginal intraepithelial neoplasia (VAIN). Their clinical information and data were reviewed and analyzed. RESULTS: Among the 79 cases, who underwent transvaginal external fascia trachelectomy, six were stage Ia1 SCC, 61 were CIN III with a large area lesion (23 cases had glandular involvement), three were CIN III complicated with VAIN, six were CIN III with persistent lesion after LEEP, two were CIN III with positive margins after LEEP, and one case had recurrence after conization. The median age of these patients was 33 years old, ranging from 23 to 40 years old. The mean operation time was 39 min (rang 20-60 min), the average amount of bleeding was 40 ml (rang 1-300 ml) and the mean hospital stay was 10 d ( rang 6-17 d). The CIN III patients complicated with VAIN received this surgery with resection of the adjacent vaginal mucosa more than 2 cm in 3.8% (3/79). The median follow-up time was 49 months (8-85 months) and none of these patients had ureteral injury or large amount of intraoperative or postoperative bleeding or post-operative recurrence. No patient complained any effect on their sexual life. Among the five patients with reproductive desire, one was at her 22 w gestation after one induced abortion and one spontaneous abortion, four patients experienced term birth in which three were cesarean section and one was natural labour. CONCLUSIONS: Transvaginal external fascia trachelectomy is a safe and effective conservative treatment for stage Ia1 SCC, CIN III with large area lesion, CIN III complicated with VAIN and CIN II-III suffering recurrence, persistent lesion or positive margins after CKC and others that are not suitable to take CKC.
