爱尔兰科学家在消化系统确认一项新器官,最早曾被达芬奇描绘

在人类身体这座设了关卡的矿井面前,科学家至今仍在不断刷新认知。

近期,爱尔兰利默里克大学外科学教授J Calvin Coffey在国际期刊《柳叶刀-肠胃病学与肝病学》上发表了一篇论文,让此前一直默默无闻的肠系膜成为“新器官”。这意味着,人体的器官数量从78改为79。这篇文章让解剖学经典教科书《格雷氏解剖学》修订了对于肠系膜的描述,从“分散独立的结构”确认为“一个连续的器官”。

早在500多年前,兼具科学家和艺术家之名的达芬奇(Leonardo da Vinci)曾画下人类最早对肠系膜的视觉认知,褶皱收拢于一角。

500多年后,Coffey给出的肠系膜结构模型清晰地展示了肠系膜的每处褶皱和弯曲。肠系膜是用来悬吊、固定肠管的腹膜一部分。在Coffey和同事的研究中,肠系膜的结构获得确认,分为小肠系膜、横结肠系膜、乙状结肠系膜、右结肠系膜、直肠系膜五个部分。

在Coffey和同事的研究中,肠系膜的结构获得确认。

在Coffey发表这篇论文之前,百来年时间里,解剖学冷落着肠系膜,因为它被认为是离散的结构,用来将肠连接、固定在腹腔的后壁上,没有什么研究价值。Coffey认为这是延续了一百多年的错误。2012年,Coffey和同事在显微镜下端详肠系膜,发现它并非如大家所知的“常识”一样,而应该是一个连续的结构。

在往后的4年时间里,Coffey和同事收集了更多的证据来表明,肠系膜实则是一个“另起灶台”的器官。

“晋身”器官一列意味着什么?描述的改变或许只是一个序幕。“当我们把它分类到器官时,我们就可以在研究相关腹部疾病时考虑到肠系膜。”Coffey表示,对肠系膜的深入研究将有助于减少开刀手术和并发症,让患者更快康复的同时降低治疗花费。

目前,关于肠系膜的结构和解剖已经清晰,但肠系膜的功能有待进一步研究。在这基础上,人类对自身消化系统的了解将更深一步。
