Abstract:
Objective To probe into the diagnostic accuracy of endometrial sampling device in the detection of endometrial lesions by cytology. Methods Endometrial cytological examination was performed on totally 193 out-patients from January to May 2008,the results were compared with the histological results by diagnostic curettage (D&C). Results The sampling qualified rate of endometrial sampling device was 93.8% (181/193) while that of D&C was 99.0% (191/193,?2=7.412,P=0.006). Thirteen patients were diagnosed with endometrial malignant lesions by D&C. In these patients,the sensitivity and specificity of cytology was 69.2% (9/13) and 100.0% (166/166),respectively;and its accuracy rate was 97.8% (175/179). By D&C 18 patients were diagnosed with endometrial hyperplasia,in whom the sensitivity and specificity of cytology was 27.8% (5/18) and 98.8% (159/161),respectively,and the accuracy rate was 91.6% (164/179). Ten patients were confirmed as having endometrial benign lesions without hyperplasia by D&C,for whom the sensitivity and specificity of cytology was 60.0% (6/10) and 98.8% (167/169) respectively,and the accuracy rate was 96.6% (173/179). The accuracy rate of endometrial cytological examination for 80 infertility patients with satisfactory sample was 100%,when the main objective was to determine whether the endometrial gland secreted or not. Conclusion Cytological examination by endometrial sampling device is feasible in the detection of endometrial malignant lesions and inspection of endometrium for infertility patients,but further discussion is necessary in the detection of endometrial benign lesions.
