GnRHa在子宫肌瘤剔除术前的临床应用(附20例分析)

目的 探讨促性腺激素释放激素激动剂(GnRHa)在子宫肌瘤剔除术前的临床应用价值及其对妊娠结局的影响。方法 回顾分析我院6年来20例行子宫肌瘤剔除术患者的基本情况,观察术前应用GnRHa治疗后子宫及肌瘤的体积变化,随访术后肌瘤复发情况,受孕时间、受孕后有无自然流产、术后分娩时间及在分娩时有无先兆子宫破裂、子宫破裂等情况。结果 应用GnRHa治疗后临床症状明显好转,子宫及其肌瘤体积明显减少,肌瘤体积缩小近50%,术后有1例复发。妊娠后未发生自然流产,平均孕周(34.0±3.5)周,1例于33周发生先兆子宫破裂,围产儿预后良好,无并发症。结论 应用GnRHa可纠正贫血,减少肌瘤复发率;能明显缩小肌瘤和子宫体积,使子宫切口小、瘢痕小,减少术时出血,减轻子宫内膜损伤,改善受孕条件,避免大肌瘤子宫全切和孕期子宫破裂的风险;延长了孕周,减少了早产的发生。

Clinical application of GnRHa before uterine myomectomy:report of 20 cases

Objective To study the clinical application of GnRHa prior to uterine myomectomy and its effect on the clinical outcome of pregnancy. Methods A retrospective review of the medical records in 20 cases of uterine myomectomy over a period of 6 years was performed. The changes of uterus and myoma volumes in response to preoperative GnRHa was observed, and the rate of relapse in the follow-up, time of impregnation, spontaneous abortion after the impregnation, time of delivery after the operation and the aura threatening uterine rupture, and uterine rupture during the delivery were assessed. Results Application of GnRHa produced significant improvement in the clinical symptoms and resulted in obviously reduced volumes of the uterus and myoma. The myoma volume reduction was close to 50% in these cases, and relapse occurred in only 1 case. No spontaneous abortion was found after GnRHa application. The average time of pregnancy was 34±3.5 weeks, and aura for uterine rupture was found in 1 case at 33 weeks of pregnancy after GnRHa application. Conclusion Application of GnRHa can correct anemia, decrease the relapse rate of myoma, reduce uterus and myoma volumes, to make possible smaller incision for uterine myomectomy that leaves smaller scar in the uterus and decrease intraoperative bleeding, also relieving endometrial injuries to promote the conditions for impregnation and minimize the risks of uterine rupture and total hysterectomy for the benefit of normal delivery.
