Value of transvaginal ultrasound-guided needle biopsy combined virtual touch tissue imaging in preoperative diagnosis of early endocervical carcinoma
Objective To investigate the possibility,safety and accuracy of transvaginal ultrasound-guided needle biopsy combined virtual touch tissue imaging(VTI)in preoperative diagnosis of early endocervical carcinoma.Methods A retrospective analysis was performed on 74 patients diagnosed as early endocervical carcinoma by postoperative pathology.We analyzed the diagnostic value of three preoperative biopsy methods including cervical biopsy under colposcopy,cervical biopsy under colposcopy plus endocervical curettage and transvaginal ultrasound combined VTI guided needle biopsy.Results The diagnostic accuracy of cervical biopsy under colposcopy,cervical biopsy under colposcopy plus endocervical curettage and transvaginal-ultrasound combined VTI guided needle biopsy was 45.00％(9/20 cases),66.67％(20/30 cases)and 83.33％(20/24 cases),respectively.For early endocervical carcinoma,the diagnostic accuracy of transvaginal-ultrasound combined VTI guided needle biopsy was higher than that of cervical biopsy under colposcopy plus endocervical curettage(P＜0.001),and higher than that of cervical biopsy under colposcopy(P＜0.001),and the differences were statistically significant.All patients in the three groups had different degrees of wound bleeding after biopsy,and the amount of bleeding in the transvaginal-ultrasound combined-guided VTI needle biopsy group was significantly less.Conclusions Transvaginal ultrasound combined VTI guided biopsy is an accurate preoperative diagnosis method for suspected early endocervical carcinoma.It is an effective supplementary method for routine"three-step"technigue and endocervical curettage in patients with suspected early endocervical carcinoma.
