A surgical procedure was developed for the simultaneous cannulation of the ileum and fistulation of the cecum in breeding-age gilts to study the effects of enteric microflora on the nutritional requirements and/or status of the pig. Flexible T-shaped cannulae were made from plastic tubing, placed surgically in the caudal part of the ileum, and exteriorized in the right paralumbar fossa. After the exteriorization of the cecal apex in the right flank area, a cecal fistual was made caudoventral to the ileal cannula. Prececocolonic contents could be collected from the ileal cannulae and/or substances could be infused into the cecum. The flexible cannulae were light weight (35 g), were easily replaced when dislodged with minimal tissue trauma and minimal discomfort to the animal, and had good animal tolerance and patency in long-term experiments. The cecal fistulae allowed the direct introduction of various substances into the cecum. There was little external projection from the abdominal wall, and the fistulae were subject to minimal leakage. The procedure did not adversely affect the subsequent health or performance of the 43 gilts used in the experiment. Postmortem examination of gilts euthanatized 12 to 26 weeks postoperatively revealed normal tissue adhesions around the surgical sites with no detrimental effects on the gastrointestinal tract.
已开发出一种外科手术方法，用于在育龄后备母猪中同时进行回肠插管和盲肠造瘘，以研究肠道微生物群对猪的营养需求和/或营养状况的影响。柔性T形插管由塑料管制成，通过手术放置在回肠尾部，并在右腰旁窝引出。在将盲肠顶端引出至右侧腹侧区域后，在回肠插管的尾腹侧制作盲肠瘘。可以从回肠插管收集结肠前内容物，和/或可以将物质注入盲肠。柔性插管重量轻（35克），当移位时易于更换，对组织创伤最小，对动物的不适最小，并且在长期实验中具有良好的动物耐受性和通畅性。盲肠瘘允许将各种物质直接引入盲肠。腹壁几乎没有外部突出，瘘管渗漏极少。该手术对实验中使用的43头后备母猪的后续健康或性能没有不利影响。对术后12至26周实施安乐死的后备母猪进行的尸检显示，手术部位周围组织粘连正常，对胃肠道没有有害影响。
