feedback2="'''Correct!''' This is most common in the colon of the pig and the horse. Some people use the term intestinal torsion to refer to twists around the root of the mesentery; strictly, this is in fact mesenteric torsion which may lead to intestinal volvulus. Volvulus is defined as a twisting of a viscus causing obstruction of blood flow. This generally occurs in the stomach (as in GDV) or small intestine, and leads to an intense, almost black, congestion as a result of haemostasis. Necrosis of the affected gut may follow. When assessing viability of gut, it is important to remember that the mucosa is more sensitive to ischaemic damage than the serosa, so at surgery, it is possible to look at the intestines and assume that they are ok when in fact the mucosa has sustained significant damage, and may not be viable. As a rule of thumb, if in doubt about viability, it is safer to remove intestine (as long as you don't remove too much to allow the remainder to function!!!) Intussusception is defined as telescoping of one section of intestine into the lumen of an adjacent section. The part of the intestine which passes into the lumen of the next section is referred to as the intussusceptum; the intestine into which the intussusceptum enters (and often becomes stuck) is known as the intussuscipiens. Intussusception occurs in all species particularly in young dogs and can involve the small intestine, caecum or colon. A hernia is displacement of intestine through a defect in the wall of the abdominal cavity; technically, in a "true" hernia, the defect through which the intestine passes is a normal opening in the abdominal cavity (e.g. umbilical hernias in young animals), whereas a "rupture" is where the normal body wall has been disrupted (e.g. diaphragmatic rupture; technically, the common perineal "hernia" should be referred to as "perineal rupture"). Intestine may become trapped in the abdominal wall defect, and if blood flow becomes disrupted, this is referred to as "strangulation". Ileus is described as a state of intestinal stasis. The intestine is usually flaccid or distended with gas; ileus is most commonly seen in horses and rabbits.
