Evaluation of hysteroscopy for the diagnoas of endometrial carcinoma and atypical hyperplasia

Objective To evaluate hysteroscopic examinations for the diagnosis of endometrial carcinoma and atypical hy-perplasia. Methods 206 patients with clinical symptoms and high risk factors of endometrial carcinoma underwent hysteroscopic examinations. Results 37 cases were diagnosed endometrial carcinoma or suspicious cancer under hysteroscopy, but 19 out of 22 cases proved pathologically had operations. Endocervix was involved in 4 cases, the rest 15 were not involved. Cytology of peritoneal washing were negative in 13 cases,1 positive,1 suspicious. In addition there were 12 cases of atypical hyperplasia diagnosed by pathologist but under hysteroscopy 4 of them were suspicious cancer, 3 hyperplasia, 4 normal or atrophy and 1 tuber-coulosis. Conclusions The endometrium was observed directly so that biopsies could be taken more accurately under hysteroscopic examinations.This method is better used for diagnosis of the early cases. It can also demonstrate the site and range of the local lesions and increase the accuracy of preoperative diagnosis or endocervical invasion, however it is not very helpful for endometrial hyperplasia.
