A new hysteroscopic classification of and nomenclature for endometrial lesions

STUDY OBJECTIVE: To establish a hysteroscopic classification of endometrial lesions based on a combined score: DESIGN: A prospective study to grade four features of endometrial lesions (thickness, surface, color, vascularization) and subdivide them as mild (low risk) and severe (high risk). SETTING: Gynecologic endoscopy unit of an obstetric and gynecology clinic. PATIENTS: Two hundred twenty-nine women with hysteroscopically diagnosed endometrial lesions. INTERVENTIONS: Hysteroscopic inspection of endometriotic lesions, with grading performed on the four features. MEASUREMENTS AND MAIN RESULTS: The sensitivity and specificity of our system were 86.9% and 87.4% for mild pathology, and 96% and 92.9% for severe pathology. CONCLUSIONS: This hysteroscopic classification of endometrial pathology can be useful for a better definition of endometrial lesions. The method has good sensitivity and specificity.
