Understanding the Endometrium at Menopause: A Hysteroscopist's View

Area of Science:

• Gynecology
• Pathology
• Surgical Endoscopy

Background:

• Postmenopausal women are at higher risk for endometrial pathologies.
• Dilatation and curettage (D&C) has diagnostic limitations, missing up to 10% of endometrial pathologies.
• Hysteroscopy is the gold standard for evaluating the endometrial cavity, though it has a ~20% false-positive rate for malignancy.

Purpose of the Study:

• To provide a pictorial guide for hysteroscopic evaluation of the postmenopausal endometrium.
• To highlight key diagnostic features of various endometrial pathologies during hysteroscopy.
• To emphasize the role of hysteroscopy with biopsy in achieving accurate diagnosis and management.

Main Methods:

• This is a pictorial review, not a clinical trial.
• The review presents hysteroscopic images of normal and pathological postmenopausal endometria.
• Diagnostic criteria focus on endometrial thickness, vascular patterns, lesion location, and surface characteristics.

Main Results:

• Hysteroscopy allows visualization of normal atrophic endometrium, cystic atrophy, benign conditions, endometrial hyperplasia, endometrial cancer, tamoxifen effects, and endometritis.
• Combining hysteroscopy with biopsy significantly increases diagnostic accuracy to approximately 100%.
• Systematic evaluation of endometrial features aids in differentiating benign from malignant conditions.

Conclusions:

• Hysteroscopy is a crucial tool for diagnosing postmenopausal endometrial pathologies.
• Biopsy guided by hysteroscopy ensures high diagnostic accuracy, improving patient management.
• This visual guide assists clinicians in interpreting hysteroscopic findings for better diagnostic and therapeutic decisions.
