Abstract: The objective of this study was to compare the value of hysteroscopy and dilatation and curettage and traditional D&C in diagnosis of endometrial carcinoma. Seventy patients with endometrial cancer were diagnosed and the operations were performed in our department. They were divided into two groups. Group A(31 patients) was examined by hysteroscopy, group B(39 patients) by D&C. There was no statistic difference in patients age, stage, grade and histological type of the disease between the two groups. Of group A, the accuracy rate for diagnosis of cervical canal involvement was 96.77%(30/31), the false positive rate was 3.23%(1/31). While in group B, the rate was 79.49%(31/39) and 15.38%(6/39) respectively. There was statistic difference (P<0.05) between two groups in estimating the involvement of cervical canal. There was no statistic difference (P>0.05) between two groups in positive peritoneal cytology. The hysteroscopy can discover the involvement of cervical mucosa more accurately in endometrial carcinoma patients, thus avoid unnecessary treatment, but the positive peritoneal cytology rate isn't improved.

Key words: hysteroscopy, endometrial neoplasms, diagnosis, dilatation and curettage
