Comparison of Fluid Hysteroscopy and CO₂ Hysteroscopy

Summary

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 were 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.
