以大网膜空肠固定,建立去系膜孤立肠段为基础,探讨大网膜蒂瓣小肠延长技术的可行性。以英国纯种Beagle幼犬为实验对象,沿近端15cm空肠对系膜缘切开浆肌层,将大网膜边缘与切开浆肌层间断缝合。7周后结扎切断该肠段系膜或纵形劈开肠段前后壁,各自间断缝合肠壁后顺蠕动吻合,形成血液供应分别来自肠系膜和大网膜的平行肠段。二期手术2周后观察实验肠段活力。结果4只犬完成二次手术,实验肠段色泽正常。组织学检查显示,实验肠段与正常肠壁结构相似。证实,大网膜空肠浆肌层固定制作孤立肠段及小肠延长技术是可行的。为治疗短肠综合征提供了可能性,但尚需进一步研究。
To omentum jejunal fixation, the establishment of mesangial isolated bowel-based, to explore the feasibility of omentum pedicled small bowel extension technology. To British purebred Beagle puppies as the experimental object, along the proximal 15cm jejunum cut open the myometrial margin of the muscular layer, the omentum and the cut open pulp muscle interrupted suture. After 7 weeks, the mesangial or longitudinal cleft anterior and posterior segments of the intestinal segment were ligated and cut off, followed by peristalsis and anastomosis intermittently. The blood supply was from the parallel bowel segment of mesentery and omental. Two weeks after surgery, observe the experimental intestinal activity. Results Four dogs completed the second operation, the color of the normal intestinal segment was normal. Histological examination showed that the experimental intestinal segments and the normal intestinal wall structure similar. Confirmed that the omentum of the omentum muscle layer fixed production of isolated bowel and small bowel extension technology is feasible. For the treatment of short bowel syndrome provides the possibility, but still need further study.
