Creation of the isolated bowel segment (IBS) by omentoenteropexy in rats and dogs consists of a two-step procedure: initial omentoenteropexy to the antimesenteric border of a jejunal segment, and division of its mesentery 6 weeks later. Viability of this IBS is maintained by the angiogenic process, which occurs at the level of the myoenteropexy. Histological studies were performed by light microscopy on the bowel wall structures of the IBS before and after the mesenteric division, as well as after a lengthening procedure performed on the IBS in one dog. The authors conclude that (1) in rats and dogs the intestinal wall structures of all IBS variants created by omentoenteropexy appear close to normal, and (2) neovascularization can be clearly detected at the level of the omentoenteropexy.
在大鼠和犬中通过网膜肠固定术创建孤立肠段（IBS）包括两步操作：首先将网膜固定于空肠段的对系膜缘，6周后切断其系膜。该IBS的存活通过血管生成过程得以维持，此过程发生在肌肠固定水平。在系膜切断前后以及对一只犬的IBS进行延长手术后，通过光学显微镜对IBS的肠壁结构进行了组织学研究。作者得出结论：（1）在大鼠和犬中，通过网膜肠固定术创建的所有IBS变体的肠壁结构看起来接近正常；（2）在网膜肠固定水平可清晰检测到新生血管形成。
