Abstract
To investigate the value and safety of biopsy guided by colposcopy in diagnosis of cervical diseases in pregnant women. From Aug. 2007 to Feb. 2009, 17 828 pregnant women who receive antenatal examination underwent cervical cytological screening thinprep cytology test (TCT) in Beijing Obstetrics and Gynecology Hospital. If abnormal cytological results were found, those pregnant women were administered by colposcopic examination and biopsy after they signed informed consent. (1) TCT: the abnormal TCT results of 1502 pregnant women (8.425%, 1502/17 828) were found in 17 828 cases. (2) Colposcopic examination: two hundred and four pregnant women underwent colposcopic examination. The rate of satisfied colposcopic imaging was 92.6% (189/204), colposcopic examination identified 125 cases with cervical inflammation or cervical intraepithelial neoplasia (CIN)I, 25 cases with CINII and 54 cases with CINIII or microinvasive squamous carcinoma (MIVC) of squamous cervical carcinoma (SCC). (3) The results of biopsy guided by colposcopy: among 204 cases, it was found 33 cases with cervical inflammation or wart, 95 cases with CINI, 28 CINII, 36 cases with CINIII and 12 cases with MIVC. (4) The rate of concordance: compared with biopsy pathologic examination, colposcopy examination found 113 cases with cervical inflammation and CINI, the rate of concordance was 90.4% (113/125). And 54 cases with CINIII or SCC diagnosed by colposcopy examination, however biopsy pathologic examination confirm 23 cases with CINIII and 10 cases with SCC at stage Ia, the concordance rate was 61% (33/54). (5) Complication: eight (3.9%, 8/204) pregnant women underwent cervical wound suturing due to continuous bleeding after colposcopy exam or biopsy. No other complications were recorded. It is necessary that TCT should be performed in pregnant women without cytological screening within one year. Colposcopic examination and biopsy were indicated if pregnant woman with abnormal cytological result were found. Pregnant women with cervicitis or CINI diagnosed by colposcopy should be followed up. If pregnant woman was suspected with CINII or advanced disease, biopsy guided by colposcopy should be performed.
