Two young adults had distal ileal obstruction at sites where a fold of mesentery extended from its posterior leaf to the antimesenteric border of the bowel. No Meckel's diverticulum or mesoumbilical band was present in either case. Clinical, gross and microscopic findings suggested that the mesenteric fold represented a remnant of vitelline vessel that persisted in the peri-ileal portion of its course. Chronic ileal obstruction was apparently due to disordered peristalsis caused by the fold tethering the adjoining posterior bowel wall. In one patient, a chronic ulcer at the site of obstruction was interpreted as being an additional complication of the congenital lesion.
两名年轻成人在肠系膜从其后叶延伸至肠管系膜对侧缘的部位发生了回肠远端梗阻。两例均未发现梅克尔憩室或脐系膜带。临床、大体及显微镜检查结果提示，肠系膜皱襞代表了在其行程回肠周围部分持续存在的卵黄管遗迹。慢性回肠梗阻显然是由于该皱襞牵拉相邻的肠后壁导致蠕动紊乱所致。在一名患者中，梗阻部位的慢性溃疡被认为是先天性病变的另一种并发症。
