mesentery

During fetal development, abnormal openings may occur in the pericecal, small bowel, transverse colon, or sigmoid mesentery, as well as the omentum, leading to mesenteric hernias.

在胎儿发育阶段，这种异的裂隙可能发生在肠旁、小肠、横结肠或乙状结肠和网，造成肠系疝。

The inferior ileocecal recess is bounded in front by the ileocecal fold, above by the posterior ileal surface and its mesentery, to the right by the cecum, and behind by the upper mesoappendix (22).

回窝在回襞前方和回肠后表面及其系的方，肠右侧，阑尾上系的后方。
