Recent advances in mesenteric anatomy have clarified the shape of the mesentery in adulthood. A key finding is the recognition of mesenteric continuity, which extends from the oesophagogastric junction to the mesorectal level. All abdominal digestive organs develop within, or on, the mesentery and in adulthood remain directly connected to the mesentery. Identification of mesenteric continuity has enabled division of the abdomen into two separate compartments. These are the mesenteric domain (upon which the abdominal digestive system is centered) and the non-mesenteric domain, which comprises the urogenital system, musculoskeletal frame, and great vessels. Given this anatomical endpoint differs significantly from conventional descriptions, a reappraisal of mesenteric developmental anatomy was recently performed. The following narrative review summarizes recent advances in abdominal embryology and mesenteric morphogenesis. It also examines the developmental basis for compartmentalizing the abdomen into two separate domains along mesenteric lines.
肠系膜解剖学的最新进展已阐明了成年期肠系膜的形态。一项关键发现是认识到肠系膜的连续性，其从食管胃交界处延伸至直肠系膜水平。所有腹部消化器官均在肠系膜内或肠系膜上发育，成年后仍直接与肠系膜相连。肠系膜连续性的确定使得腹部可分为两个独立的腔室。这两个腔室分别是肠系膜区域（腹部消化系统以其为中心）和非肠系膜区域，后者包括泌尿生殖系统、肌肉骨骼框架和大血管。鉴于这一解剖学终点与传统描述有显著差异，最近对肠系膜发育解剖学进行了重新评估。以下叙述性综述总结了腹部胚胎学和肠系膜形态发生的最新进展。它还探讨了沿肠系膜线将腹部分为两个独立区域的发育基础。
