Nodular torsion of small intestine

This disease is characterized by formation of a nodule in a haori string pattern or a paper bundle pattern caused by twining of a part of the intestine around another part. In this 8-year-old gelding horse, the jejunum was tied up by the adjacent part, and the mesenterium in this area was strangled and pulled. The part of the small intestine showing torsion is bluish red - blackish red, swollen, and shows enlarged mesenteric blood vessels. (register No. 4313)
