Polypectomy in premenopausal women with abnormal uterine bleeding: Effectiveness of hysteroscopic removal

Study objectiveTo estimate the effectiveness of hysteroscopic polypectomy in premenopausal women with abnormal uterine bleeding and to identify prognostic factors for persistence or recurrence of symptoms after polypectomy.DesignRetrospective study (Canadian Task Force classification II-3).SettingUniversity teaching hospital.PatientsPremenopausal women with abnormal uterine bleeding.InterventionHysteroscopic polypectomy, regardless of whether combined with endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device.Measurements and main resultsSeventy-eight consecutive patients met the inclusion criteria and were followed over time. Data were retrieved from medical records or from additional questionnaires sent to the patients. Failure of treatment was defined as persistence or recurrence of abnormal uterine bleeding after polypectomy, requiring further treatment. The mean age was 44.2 years (SD 5.2, 95% CI 33.9–54.4 years). Intervention-free survival after polypectomy, as calculated by Kaplan-Meier survival analysis, was 41.1% (SE 8.3%, 95% CI 24.8%–57.4%) after 4 years for patients who underwent only hysteroscopic polypectomy and 54.7% (SE 13.6%, 95% CI 28.0%–81.4%) for patients who underwent a polypectomy combined with endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device (p = .08). Cox regression analyses revealed no statistically significant predictors for persistence or recurrence of symptoms after polypectomy.ConclusionNearly 60% of patients required further treatment for persistence or recurrence of abnormal uterine bleeding 4 years after hysteroscopic polypectomy. Although not significant, outcome of treatment tended to improve by combining polypectomy with either an endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device.
