AHJ：输卵管切除术并不增加心脏病风险

与一些现代研究工作相反，一项取而代之的美国研究工作推断出早熟男同性恋进行时乳房摘除术（伴或不伴睾丸摘除）后，糖尿病的效用并未回升。这些男同性恋外科的效用却是高于自然绝经的男同性恋，该取而代之研究工作真是。

西雅图大学首席作家Karen A. Matthews及上司在一份调查结果中记下了他们的推断出，这份调查结果蓝图于本周在线发布于《美国脑癌学会杂志》。

Matthews，西雅图的一位杰出成就的心理学家博士和流行病学与心理学博士，在一份取而代之闻公报中声明，这些结果对正在考虑到乳房摘除术的早熟男同性恋来真是应该是鼓舞人心的：

“研究工作结果表明，相对于自然绝经后，乳房摘除术后的外科效用系数水平不大不太可能回升，”Matthews真是。

乳房摘除术与外科效用

乳房摘除术是一种常见的移除男同性恋乳房的治疗操控。有时，病患还移除睾丸，以降低睾丸癌效用。

有时不太可能轻微必需进行时该操控，比如因为肝癌、乳房下垂、橡胶所发肌瘤，或因为非常为重的月经过多与痛经，但与此同时，和所有治疗一所发，仍要各种因素其收益与效用。

因为雌激素改变，在绝经从前进行时乳房摘除术常导致更年期提从前。

一些现代研究工作表明乳房摘除术提高糖尿病的长期效用，而糖尿病是男同性恋头号杀手。而且他们推断出，如果同时摘除睾丸，该效用将更佳。

但是该见解缺失，主要因为这些研究工作倾向于评量乳房摘除术与/或睾丸摘除术多年之后的外科效用，而从未将她们在治疗之从前就不太可能有的效用考虑到进去。

研究工作者们好好了什么

而在该项取而代之研究工作中，Matthews及其上司随访了3,302位美国绝经从前男同性恋11年。这些男同性恋参加了全国男同性恋研究工作（SWAN）。

研究工作伊始，当这些男同性恋转为到SWAN时，她们42-52岁，乳房完整，有至少1个睾丸，且从未使用雌激素疗法。

在随访期间，每年给她们好好评量。在此期间，大部分男同性恋达到自然绝经年龄，一些进行时了乳房摘除术伴睾丸摘除术，而一些则不伴睾丸摘除术。

进行时乳房摘除术的主要情况是橡胶所发肌瘤、月经过多和慢性下颚痛。

研究工作者在乳房摘除术从前后评量了自发性的外科效用，并将这些原始数据与那些自然绝经的男同性恋最后一次月经从前后的效用比起。

Matthews及其上司真是，他们的研究工作是首项多民族研究工作，了进行时乳房摘除术与自然绝经的男同性恋的外科效用系数的每年预期改变。

推断出了什么

该深入研究辨识乳房摘除术从前后与自然绝经从前后心血管效用系数时有变动，在不尽相同个体，乳房摘除术者与自然绝经者波动方式也迥然不尽相同；同时，总体波动方式也辨识乳房摘除术者心血管效用并未回升，研究工作者们真是。并且，此情况在所有白种人组都一所发。

并且，即使在调整不太可能的影响系数——比如人体质量指数（BMI）——之后，情况仍一所发。乳房摘除术伴睾丸摘除术后，BMI确实有所回升。

情况是什么

Mathews真是他们却是考虑到到为什么他们的推断出与辨识乳房摘除术升高外科效用的现代研究工作不尽相同。

一个情况不太可能是，他们从未将年长男同性恋纳入研究工作，而更早进行时乳房摘除术导致的外科效用更佳。

另一个情况，Matthews真是，不太可能是因为该研究工作排除了因为肝癌而进行时乳房摘除术的男同性恋。

SWAN由国家老年医学研究工作所、国立护理研究工作所、国立卫生研究工作院、男同性恋健康研究工作室和补足与替代医学中心协力倡议。

2011年，《内科学档案》杂志谈到，来自旧金山加利福尼亚大学的研究工作者们报导，他们推断出进行时了乳房摘除术伴睾丸摘除术的男同性恋时有发生睾丸癌的效用降低，并且时有发生其它类型肝癌、脑癌或髋骨折的效用并未升高。

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."
