Evaluation of pre-operative endometrial biopsy accuracy and etiological distribution in abnormal uterine bleeding using the PALM–COEIN classification

Among patients undergoing hysterectomy for AUB, structural pathologies, particularly leiomyomas, constitute the primary reason for hysterectomy. Although pre-operative EB is successful in ruling out pathologies, it may be insufficient in detecting focal lesions and some pre-malignant conditions due to its low sensitivity. Therefore, EB results should be supported by advanced diagnostic imaging methods, especially when clinical suspicion exists during the decision-making process for hysterectomy.
