A T-cannula was fitted permanently into the ileum of ten mature ponies to quantify the role of the prececal and postileal segments of the digestive tract in equine nutrition studies. The ponies were anesthetized, positioned in left lateral recumbency, and the distal small intestine was exteriorized through a right paralumbar incision. A silastic T-cannula was inserted through a 2-cm longitudinal incision into the lumen of the ileum, on the antimesenteric surface, and sutured to the ileum. The stem of the cannula was exteriorized through a 2-cm circular skin incision, 6 cm caudal to the 16th rib. Nine ponies were alive with functional cannulas after six months. Primary complications associated with cannulation of the ileum were clinical signs of depression and dehydration produced by leakage of intestinal contents around the stem of the cannula. These complications were resolved with fluid and electrolyte therapy.
将一个T型套管永久性地安装在十匹成年矮种马的回肠中，以量化消化道盲肠前段和回肠后段在马营养研究中的作用。将矮种马麻醉，使其左侧卧，通过右腰旁切口将远端小肠引出体外。将一个硅橡胶T型套管通过一个2厘米的纵向切口插入回肠腔，位于肠系膜对侧表面，并缝合到回肠上。套管的柄通过一个2厘米的圆形皮肤切口引出，该切口位于第16肋骨尾侧6厘米处。六个月后，九匹矮种马的套管功能正常且存活。与回肠插管相关的主要并发症是套管柄周围肠内容物渗漏导致的抑郁和脱水的临床症状。这些并发症通过液体和电解质疗法得到解决。
