The purpose of this study was to describe national rates and trends of prophylactic bilateral oophorectomy or remaining oophorectomy (BO/RO) at hysterectomy in women without specific gynecologic disease.
Data from the National Hospital Discharge Survey were analyzed for 1979-2004. Hysterectomies were divided into 2 groups: (1) hysterectomy with BO/RO and (2) hysterectomy alone (> or =1 ovary remaining). Age-adjusted rates (AARs) were calculated with 2000 US census data.
Approximately 3,686,000 hysterectomies with BO/RO were performed from 1979-2004. AARs of hysterectomy with BO/RO decreased during this period; the AARs in women > or =50 years old increased. The number of hysterectomies alone was 5,461,100, and AARs of hysterectomy alone decreased significantly from 2.9 per 1000 women in from 1979-1981 to 1.1 per 1000 women in 2001 (P < .001). The proportion of women who underwent hysterectomy with BO/RO increased from 29% in 1979 to 45% in 2004.
Although AARs of prophylactic BO/RO decreased from 1979-2004, the actual proportion of BO/RO at hysterectomy increased.
本研究旨在描述无特定妇科疾病的女性在子宫切除术中预防性双侧卵巢切除术或保留卵巢切除术（BO/RO）的全国发生率和趋势。
对 1979 年至 2004 年的国家医院出院调查数据进行了分析。将子宫切除术分为两组：（1）行 BO/RO 的子宫切除术和（2）仅行子宫切除术（保留至少 1 个卵巢）。使用 2000 年美国人口普查数据计算年龄调整率（AAR）。
1979 年至 2004 年期间共进行了约 368.6 万次 BO/RO 子宫切除术。在此期间，行 BO/RO 的子宫切除术 AAR 下降；年龄≥50 岁的妇女的 AAR 增加。仅行子宫切除术的数量为 546.11 万次，仅行子宫切除术的 AAR 从 1979-1981 年的每 1000 名妇女 2.9 次显著下降至 2001 年的每 1000 名妇女 1.1 次（P<.001）。行 BO/RO 子宫切除术的妇女比例从 1979 年的 29%增加到 2004 年的 45%。
尽管 1979 年至 2004 年期间预防性 BO/RO 的 AAR 下降，但实际行 BO/RO 的子宫切除术的比例增加。
