title: Comparison of fluid hysteroscopy and CO2 hysteroscopy.
abstract: A total of 247 women were subjected to liquid and CO2-hysteroscopy used as adjuncts in the screening of bleeding abnormalities in reproductive and post-menopausal groups. A point system of scoring proved quite useful. Using CO2-hysteroscopy the percentage of the detected malignancies corresponded to the percentages obtained by curettage in the age group of these patients. In liquid hysteroscopy, a group already suspicious for malignancy yielded a higher percentage of malignancies detected than normally expected. In post-menopausal women 41.7% of the cases examined wer malignant. The nine point scoring system used in liquid hysteroscopy correlated well with the histological findings. Both hysteroscopic techniques have their application and both are complementary, since they can be used for different indications in the visualization of the uterine cavity.
