[Effect of cervical conization through hysteroscopy for cervical intraepithelial neoplasia III].

OBJECTIVE

To evaluate the therapeutic effect of cervical conization through hysteroscopy in the treatment of cervical intraepithelial neoplasia (CIN) III.

METHODS

Seventy-four patients with CIN III underwent cervical conization through hysteroscopy (TCRC group), and 65 received cold knife conization (CKC group). The operating time, volume of blood loss, concordance rate with pathology, recurrence rate, rate of cervix adhesion and pregnancy rate were compared between the two groups.

RESULTS

The operating time, mean blood loss, cure rate, and recurrence rate were 15.1∓3.2 min, 12.5∓1.8 ml, 94.6%, and 5.4% in TCRC group, respectively, as compared with those of 25.8∓3.8 min, 21.6∓2.4 ml, 81.5%, and 18.5% in CKC group, all showing significant differences between the two groups (P<0.05).

CONCLUSION

Compared with CKC, TCRC has such advantages as less blood loss, shorter operating time, more accurate lesion localization, fewer complications, higher cure rate, and lower recurrence rate without significant adverse effect on pregnancy.
