The designation of the subperitoneal space emphasizes the continuum of the potential space of extraperitoneal and intraperitoneal areolar tissue traversed by blood vessels, lymphatics, and nerves. Across its root, the subserous connective tissue of the small bowel mesentery is anatomically continuous with that deep to the posterior parietal peritoneum. There is thereby provided an avenue of spread from multiple sites to and from the small bowel mesentery and its relationships. These include perforated lesions of the bowel, pancreatitis, lymphoma, neuroblastoma, leiomyosarcoma of small bowel, and hemorrhage of retroperitoneal and pelvic origin.
腹膜下间隙的命名强调了腹膜外和腹膜内疏松结缔组织潜在间隙的连续性，血管、淋巴管和神经穿行其中。在小肠系膜根部，小肠系膜的浆膜下结缔组织在解剖学上与壁腹膜后方深处的结缔组织相连。由此提供了一条在多个部位与小肠系膜及其相关结构之间扩散的途径。这些部位包括肠道穿孔性病变、胰腺炎、淋巴瘤、神经母细胞瘤、小肠平滑肌肉瘤以及腹膜后和盆腔来源的出血。
