Do endometrial lesions require removal? A retrospective study

This study aimed to evaluate the management of asymptomatic intrauterine lesions detected by ultrasonography. Patients who underwent diagnostic hysteroscopy for asymptomatic lesions, including pre- and post-menopausal endometrial polyps, post-menopausal endometrial thickening (ET ≥5 mm) and reduplicative endometrial heterogeneity detected by transvaginal ultrasonography (TVUS), were recruited for this study. In the 792 recruited patients, the symptom-free focal masses within the uterine cavity detected by TVUS included 558 patients with pre- or post-menopausal endometrial polyps and 234 patients with postmenopausal endometrial thickening. No pre-menopausal patient presented with carcinoma. The polyp diameter (PD) was not identified as an independent risk factor for malignancy in this study. A significant difference (P = 0.036,
