Abstract: Hysteroscopy has been considered to be a gold standard for the diagnosis of endometrial
carcinoma. Hysteroscopy and guided biopsy can be performed to accurate the diagnosis of endometrial
carcinoma by avoiding blinding curettage. Many studies report that diagnostic hysteroscopy didn’t increase the
risk of positive peritoneal cytology，and also had no adverse effect on prognosis in endometrial cancer patients.
This is a review about the diagnostic accuracy and advances of whether hysteroscopy could increase the risk of
positive peritoneal cytology in endometrial cancer patients.
