RESUMO
STUDY OBJECTIVE: To analyze factors that contribute to long-term success of loop endometrial resection (ER). DESIGN: Observational cohort study (Canadian Task Force classification II-2). SETTING: Tertiary care university hospital. PATIENTS: Two hundred eighty-six premenopausal women with menometrorrhagia resistant to medical treatment. INTERVENTION: Loop endometrial resection. MEASUREMENTS AND MAIN RESULTS: Mean follow-up was 47 months. Life table analysis with log rank test was determined to calculate the risk of hysterectomy after ER. Patient age, length of follow-up, adenomyosis, and uterine size were analyzed independently. More than 75% of patients benefited from the procedure, avoiding hysterectomy after 5 years. CONCLUSION: Length of follow-up, patient age, and the presence of adenomyosis strongly influence the long-term success of ER. The procedure should be considered an intermediate step between medical treatment and hysterectomy.
