Design: Prospective comparative coorte. Setting: Tertiary public hospital, university teaching center. Seventy-three patients with abnormal uterine bleeding unresponsive to clinical treatment submitted to endometrial ablation from October 2011 to September 2013. Methods and Main Outcome Measures: Patients were assigned to either monopolar U-shaped electrode resection with rollerball electrocoagulation (group A, n = 36) or rollerball electrocoagulation alone (group B, n = 37). Mean follow-up length was 359 (280 - 751) and 370 days (305 - 766) in groups A and B, respectively. Bleeding pattern, associated symptoms, failure/success rates were assessed 30, 90, 180 and 360 days post-procedure. Findings: Patient characteristics were similar in both groups (P ≥ 0.05). Surgery duration (mean of 48.5 [±12.0] vs. 31.9 [±5.6] min, P Conclusions: Endometrial ablation using rollerball electrocoagulation alone may be considered safer than resection with rollerball electrocoagulation, which requires shorter surgical time and less distention medium, and is associated with lower postoperative vaginal discharge incidence. Success rate did not statistically differ between groups, but study parameters in absolute values and percents were superior in group B.展开更多

It has been widely adopted clinically in many countries. In this study, we compare the outcome of MEA and total hysterectomy for menorrhagia.Methods Sixty patients with menorrhagia were divided into MEA group or total hysterectomy （control） group （30 in each）. The intra operative blood loss, operating time, either preserving the uterus or not, and length of recovery time in the two groups were compared. The independent samples t test was used to analyse our data in the study. Results In comparing the MEA group and the control group, the effective rates were 96% （29/30） and 100% （30/30, χ^2 = 0, P = 1.0）. The operating time was （4.0± 1.1） minutes and （68.3±1.9） minutes （t =-160.42, P = 0.00）. The mean blood loss was 0 ml and 50 ml, respectively. Conclusions The curative effect of MEA is similar to that of total hysterectomy. When considering preservation of the uterus and postoperative recovery, MEA is obviously superior to total hysterectomy.展开更多
