Abstract:
Objective To explore the clinical value of colposcopy directed biopsy in diagnosis of vaginal intraepitheal neoplasia (VaIN).Methods The clinical data of 106 VaIN patients diagnosed by colposcopy directed biopsy were reviewed and analyzed retrospectively.In the past medical history of 106 patients,46 patients had cervical cancer history,43 patients had cervical intraepithehal neoplasia history,13 patients had previous hysterectomy because of benign disease and 4 patients had uncertain past medical history.Results Among 106 patients,97 patients(91.51％,97/106) had abnormal pap smears of vagina,9 patients (8.49％,9/106) had abnormal pap smears of cervix.Histological analysis revealed that 69 patients were VaIN Ⅰ,24 patients were VaIN Ⅱ,13 patients were VaIN Ⅲ.The high-risk human papilloma virus (HPV) test at diagnosis were positive in 98 patients (92.45％,98/106),negative in 8 patients (7.55％,8/106).Eighty-seven patients VaIN were localized in the upper one third of the vagina,19 patients VaIN were localized in other parts of vaginal wall.Ninety-eight patients VaIN affected to the multifocal vaginal wall,8 patients VaIN affected to the focal vaginal wall.Conclusions It has highly therapeutic value of colposcopy directed biopsy in diagnosis of VaIN.But should closely correlated to past medical history,colposcopy should performed on the whole vagina wall and multiple punch biopsy to elevated positive rate.
