The conventional model of abdominal anatomy described multiple mesenteries. Dissection techniques were based on this. Recent studies demonstrate the mesentery is continuous from duodenojejunal flexure to anorectal junction. Given this, it is important to update dissection techniques related to the mesentery in the cadaveric setting. A technique of mesenteric dissection was developed and tested in a cohort of 20 adult human cadavers (12 male and 8 female). As the technique enabled excision of the mesentery as a single unit, it was possible to characterize the anatomy of the mesentery. The technique developed enabled dissection of an intact and continuous mesentery in all cadavers examined. Examination of the mesentery demonstrated that a mesoduodenum was present in all cases. The mesentery was continuous from the mesoduodenum to the mesorectum and ended at the level of the anorectal junction. A technique was developed that reproducibly enabled dissection of an intact and continuous mesentery from the duodenum to the anorectal junction. A mesoduodenum was consistently observed and noted to be in continuity with the remainder of the mesentery.
传统的腹部解剖模型描述了多个系膜。解剖技术就是基于此而来。最近的研究表明，系膜从十二指肠空肠曲延伸至肛管直肠交界处，呈连续状态。鉴于此，在尸体解剖中更新与系膜相关的解剖技术很重要。我们开发了一种系膜解剖技术，并在20具成年人体尸体（12例男性和8例女性）中进行了测试。由于该技术能够将系膜作为一个整体切除，因此有可能对系膜的解剖结构进行描述。所开发的技术能够在所有检查的尸体中解剖出完整且连续的系膜。对系膜的检查表明，所有病例均存在十二指肠系膜。系膜从十二指肠系膜延续至直肠系膜，并在肛管直肠交界处水平结束。我们开发了一种技术，可重复性地从十二指肠至肛管直肠交界处解剖出完整且连续的系膜。始终观察到十二指肠系膜，并注意到它与系膜的其余部分相连。
