title: Factors influencing long-term outcome of loop endometrial resection.
abstract: OBJECTIVE
  To analyze factors that contribute to long-term success of loop endometrial resection (ER).
  
  
  METHODS
  Observational cohort study (Canadian Task Force classification II-2).
  
  
  METHODS
  Tertiary care university hospital.
  
  
  METHODS
  Two hundred eighty-six premenopausal women with menometrorrhagia resistant to medical treatment.
  
  
  METHODS
  Loop endometrial resection.
  
  
  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.
  
  
  CONCLUSIONS
  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.
