Summary
Microwave endometrial ablation (MEA) offers similar effectiveness to hysterectomy for menorrhagia. MEA is superior for uterine preservation and faster recovery, making it a preferred minimally invasive option.
Area of Science:
- Gynecology
- Minimally Invasive Surgery
Background:
- Menorrhagia is a common gynecological condition.
- Microwave endometrial ablation (MEA) is a minimally invasive surgical option.
- MEA is increasingly adopted globally for menorrhagia treatment.
Purpose of the Study:
- To compare the clinical outcomes of MEA and total hysterectomy for menorrhagia.
- To evaluate efficacy, operative time, blood loss, and recovery between MEA and hysterectomy.
Main Methods:
- Sixty patients with menorrhagia were randomized into MEA or total hysterectomy groups (30 each).
- Key metrics included intraoperative blood loss, operating time, uterine preservation, and recovery duration.
- Data were analyzed using the independent samples t test.
Main Results:
- Effective rates were comparable: 96% for MEA and 100% for hysterectomy (P=1.0).
- MEA significantly reduced operating time (4.0 ± 1.1 min) versus hysterectomy (68.3 ± 1.9 min).
- MEA resulted in no intraoperative blood loss compared to 50 ml for hysterectomy.
Conclusions:
- MEA demonstrates comparable curative effects to total hysterectomy for menorrhagia.
- MEA offers significant advantages in uterine preservation and postoperative recovery.
- MEA is a superior alternative to hysterectomy when these factors are considered.
