Objective · To investigate the relationship between the results of thin prep cytologic test (TCT), high-risk human papillomavirus (Hr-HPV) detection and vaginal intraepithelial neoplasia (VAIN) after hysterectomy. Methods · A retrospective study was conducted of 56 patients with VAIN after hysterectomy. The analysis included TCT and Hr-HPV examination, clinical data and the relationship between Hr-HPV examinenation and histopathological examination of colposcopy. Results · Postoperative follow-up of TCT and Hr-HPV parallel pathological examination showed that 56 patients had vaginal stump lesions, including cervical factor hysterectomy accounted for 5.81% (45/775) and non cervical factor hysterectomy accounted for 0.19% (11/5 933). The difference was statistically significant (P=0.000). In 56 cases of patients with vaginal stump lesions, Hr-HPV infection were 40 cases (accounting for 71.43%), uninfected patients were 16 cases (accounting for 28.57%). The Hr-HPV infection rates of cervical hysterectomy and non cervical factor hysterectomy patients were 80.00% (36/45) and 36.36% (4/11) respectively, and the difference was statistically significant (χ2= 6.248, P= 0.012). TCT results showed that the incidence of squamous intraepithelial lesions were 42.22% (19/45) and 9.09% (1/11) respectively. Conclusion · The Hr-HPV infection rate and the morbidity of VAIN of the patients undergone hysterectomy due to the cervical lesion factors is higher than those who had none cervical lesion factors. In order to identify VAIN early, patients who have the history of hysterectomy should undergo careful evaluation of cervical and vaginal circumstance before surgery and the routine examinations of TCT and Hr-HPV in the follow-up.
