Effectiveness of Hysteroscopic Techniques for Endometrial Polyp Removal: The Italian Multicenter Trial

STUDY OBJECTIVE: To compare the effectiveness and safety of different techniques of hysteroscopic polypectomy. DESIGN: Multicenter, prospective observational trial (Canadian Task Force classification II-2). SETTING: Nineteen Italian gynecologic departments (university-affiliated or public hospitals). PATIENTS: Consecutive patients suffering from endometrial polyps (EPs). INTERVENTIONS: Hysteroscopic polypectomy, as performed through different techniques. MEASUREMENTS AND MAIN RESULTS: Included in the study were 1404 patients (with 1825 EPs). The setting was an ambulatory care unit in 40.38% of the cases (567 women), of whom 97.7% (554) did not require analgesia/anesthesia. In the remaining 59.62% of women (837 women), the procedures were performed in an operating room under mild sedation, local or general anesthesia. Minor complications occurred in 32 patients (2.27%), without significant differences between the techniques used (p = ns). Uterine perforation occurred in 14 cases, all performed in the operating room with some kind of anesthesia, only 1 with a vaginoscopic technique and the remaining during blind dilatation (odds ratio [OR], 19.98; 95% confidence interval [CI], 1.19-335.79; p = .04). An incomplete removal of EPs was documented in 39 patients. Logistic regression analysis showed that a higher risk of residual EPs was associated with the use of a fiber-based 3.5-mm hysteroscope (OR, 6.78; 95% CI, 2.97-15.52; p <.001), the outpatient setting (OR, 2.17; 95% CI, 1.14-4.14; p = .019), and EPs located at the tubal corner (OR, 1.98; 95% CI, 1.03-2.79; p = .039). No association between incomplete EP removal and EP size or number was recorded (p = ns), as well as with the other variables evaluated. CONCLUSION: Outpatient polypectomy was associated with a minimal but significantly higher risk of residual EPs in comparison with inpatient polypectomy. Conversely, inpatient polypectomy was associated with a considerably higher risk of uterine perforation and penetration in comparison with office hysteroscopy. Because of lower intraoperative risks and higher cost-effectiveness, office hysteroscopy may be considered, whenever possible, as the gold standard technique for removing EPs

Prevalence and predictors of atypical histology in endometrial polyps removed by hysteroscopy: A secondary analysis from the SICMIG hysteroscopy trial

Background: The aim of this study is to assess the prevalence of atypical hyperplasia (AH) and endometrial cancer (EC) within endometrial polyps (EPs) removed by hysteroscopy.Methods: Hysteroscopic polypectomy interventions were performed over 1436 consecutive patients with Eps to complete a prospective observational trial (Canadian Task Force Classification II-2) including 19 Italian Gynecologic Departments (University-Affiliated or Public Hospitals) for a secondary multicenter analysis.Results: At histological analysis, in 1404 patients (97.8%) EPs were classified as benign, whereas in 32 patients (2.2%) EPs were diagnosed as atypical (i.e. with All or EC). Specifically, All and EC were found in 17 (1.2%) and 15 (1.0%) cases, respectively. Risk factor analysis showed that menopausal status, BMI and size of EPs were associated with increased risk of atypical EPs (p<0.0001). Abnormal uterine bleeding, EPs number, contraceptive therapy and tamoxifen were not associated with increased risk of atypia (p=ns). The cut-off points for increased risk of atypical polyps were 54.2 years old, BMI of 25.3 and EP size of 2.2 cm. Hysterectomy specimens were analyied in 21 women with atypical EPs, showing the concomitant presence of atypical tissue in non-polypoid endometrium in the majority of patients (n=14 women, 66.6%).Conclusion: The prevalence of endometrial cancer and atypical hyperplasia in endometrial polyps is low, although it is increased in women who are overweight, older than 54 years of age or with a polyp larger than 2cm
