A new hysteroscopic classification of and nomenclature for endometrial lesions.

Study objectiveTo establish a hysteroscopic classification of endometrial lesions based on a combined score:DesignA prospective study to grade four features of endometrial lesions (thickness, surface, color, vascularization) and subdivide them as mild (low risk) and severe (high risk).SettingGynecologic endoscopy unit of an obstetric and gynecology clinic.PatientsTwo hundred twenty-nine women with hysteroscopically diagnosed endometrial lesions.InterventionsHysteroscopic inspection of endometriotic lesions, with grading performed on the four features.Measurements and main resultsThe sensitivity and specificity of our system were 86.9% and 87.4% for mild pathology, and 96% and 92.9% for severe pathology.ConclusionsThis hysteroscopic classification of endometrial pathology can be useful for a better definition of endometrial lesions. The method has good sensitivity and specificity.
