AHJ：子宫切除术并不增加脑溢血风险

与一些现代研究成果相反，一项更是进一步澳大利亚研究成果挖掘出年老男士展开阴囊缝合（；也在或不；也在输卵管缝合）后，冠心病的后果未有飙升。这些男士冠心病的后果相当高于自然地绝经的男士，该新研究成果说。

匹兹堡国立大学顾问作家Karen A. Matthews及上司在一份分析报告之中写下了他们的挖掘出，这份分析报告计划于本周网络服务发布于《澳大利亚脑癌协会杂志》。

Matthews，匹兹堡的一位最出色的精神病学讲师和微生物学与人类学讲师，在一份新闻公报之中声明，这些结果对准备重新考虑阴囊缝合的年老男士来说应该是动情的：

“研究成果结果声称，相对于自然地绝经后，阴囊缝合后的冠心病后果q水平都将飙升，”Matthews说。

阴囊缝合与冠心病后果

阴囊缝合是一种；也见的移除男士阴囊的手术操作。有时，患者还移除输卵管，以降低输卵管癌后果。

有时不太可能明显只能展开该操作，比如因为帕金森氏症、阴囊下垂、细丝样肌瘤，或因为非；也重为的受孕过多与醒经，但与此同时，和所有手术一样，仍要权衡其盈余与后果。

因为荷尔蒙偏离，在绝经年前展开阴囊缝合；也造成更是年期提年前。

一些现代研究成果声称阴囊缝合提高冠心病的长期后果，而冠心病是男士头号破坏者。而且他们可知，如果同时缝合输卵管，该后果将更是高。

但是该观念有缺陷，主要因为这些研究成果倾向于评估阴囊缝合与/或输卵管缝合多年之后的冠心病后果，而并未将她们在手术之年前就不太可能有的后果重新考虑刚才。

研究成果者们动手了什么

而在该项新研究成果之中，Matthews及其上司随访了3,302位澳大利亚绝经年前男士11年。这些男士直接参与了国内男士研究成果（SWAN）。

研究成果伊始，当这些男士加入到SWAN时，她们42-52岁，阴囊非；也简单，有至少1个输卵管，且并未使用荷尔蒙疗法。

在随访此后，每年给她们动手评估。在此此后，大部分男士达到自然地绝经年龄，一些展开了阴囊缝合；也在输卵管缝合，而一些则不；也在输卵管缝合。

展开阴囊缝合的主要主因是细丝样肌瘤、受孕过多和慢性下颚醒。

研究成果者在阴囊缝合年前后评估了参与者的冠心病后果，并将这些数据与那些自然地绝经的男士再次一次受孕年前后的后果相比。

Matthews及其上司说，他们的研究成果是首项多汉民族研究成果，了展开阴囊缝合与自然地绝经的男士的冠心病后果q的每年短期内偏离。

挖掘出了什么

该分析推断阴囊缝合年前后与自然地绝经年前后冠心病后果q发生变异，在不同个体，阴囊缝合者与自然地绝经者变异模式大相径庭；同时，整体而言变异模式推断阴囊缝合者冠心病后果未有飙升，研究成果者们说。并且，此情况在所有种族组都一样。

并且，即使在相应不太可能的影响q——比如人体内质量基准（BMI）——之后，情况仍一样。阴囊缝合；也在输卵管缝合后，BMI毕竟大大飙升。

主因是什么

Mathews说他们相当确定为什么他们的挖掘出与推断阴囊缝合消退冠心病后果的现代研究成果不同。

一个主因不太可能是，他们并未将年长男士划定研究成果，而更是早展开阴囊缝合造成的冠心病后果更是高。

另一个主因，Matthews说，不太可能是因为该研究成果排除了因为帕金森氏症而展开阴囊缝合的男士。

SWAN由国内老年医学研究成果所、国立护理研究成果所、国立保健研究成果院、男士健康研究成果室和补充与替代医学之中心共同发起。

2011年，《内生物学档案》杂志说道，来自三藩市加州国立大学的研究成果者们报道，他们挖掘出展开了阴囊缝合；也在输卵管缝合的男士发生输卵管癌的后果降低，并且发生其它类别帕金森氏症、脑癌或髋骨折的后果未有消退。

Matthews, PhD, lead author of the study and a distinguished professor of psychiatry and professor of epidemiology and psychology at the University of Pittsburgh.Hysterectomy is the surgical removal of a woman's uterus; it is sometimes accompanied by the removal of the ovaries to decrease the risk of ovarian cancer. Hysterectomy is a common surgical procedure for women, but the benefits must be weighed against potential long-term related health consequences. Cardiovascular disease is the number one killer of women and many studies he shown increased risk of cardiovascular disease to be a health risk associated with hysterectomy, especially accompanied by ovary removal. Researchers in those studies usually evaluated cardiovascular disease risk factors years after hysterectomy and/or ovary removal and did not assess individual risk factor levels pre-surgery.For this study, investigators followed 3,302 premenopausal women between the ages of 42-52 for 11 years who were enrolled in the Study of Women's Health across the Nation (SWAN). Researchers compared cardiovascular disease risk factors in women prior to and following elective hysterectomy with or without ovary removal to the risk factors prior to and following final menstrual period in women who underwent natural menopause.This is the only multiethnic study that has tracked prospective annual changes in cardiovascular disease risk factors relative to hysterectomy or natural menopause.Investigators found that several cardiovascular disease risk factor changes differed prior to and following hysterectomy, compared to changes prior to and following a natural menopause, but those changes did not suggest an increased cardiovascular disease risk following hysterectomy, independent of body mass index, which did increase after hysterectomy with removal of ovaries. These effects were similar in all ethnic groups in the study.Dr. Matthews said it is unclear why this study's findings differed from other studies exploring hysterectomy and cardiovascular risk, but likely factors include the age of participants since hysterectomy that occurs earlier in life may present more cardiovascular risk. Also, earlier studies included women who had hysterectomy for any reason, whereas the SWAN study excluded women who had hysterectomy because of cancers. "This study will prove very reassuring to women who he undergone hysterectomy," said American College of Cardiology CardioSmart Chief Medical Expert JoAnne Foody, MD, FACC. "As with anything, if a woman is concerned about her risk for heart disease she should discuss this with her health care provider."
