→Intussusception
=====Intussusception=====
=====Intussusception=====
This is a condition in which one part of the intestine "telescopes" inside another. Usually this obstructs the blood flow to the inner part, and so forms a strangulating obstruction. Intussusception can occur within the small intestine, and also between small intestine and caecum (ileo-caecal intussusception). The latter is predisposed by Anoplocephala perfoliata tapeworm infection. When working up an acute abdominal case, it must be borne in mind that this form of colic is serious and necessitates surgery, however, peritoneal fluid changes will not usually be seen, as will often be found in a surgical colic. This is because the strangulated portion of gut (the inside of the "telescope"), is contained within an intact piece of intestine, so leaking fluid and protein is contained from the peritoneal cavity.
