colonic aganglionosis

see colonic aganglionosis.

see megacolon.

colonic atresia

affected neonates appear normal at birth but develop abdominal distention quickly. No feces are passed and death occurs at about one week unless surgical repair is effected. The defect occurs sporadically in most species. In horses and cattle it can be inherited, in cattle it can result from over-vigorous palpation of the fetus between 35 and 41 days gestation at pregnancy diagnosis, but the cause is not determined in most cases.

colonic bands

see teniacoli.

colonic constriction

due to contraction of peritoneal adhesions in horses; causes chronic or intermittent colic.

colonic contraction

permanent inability of colon to dilate due to congenital aganglionosis.

colonic crypt

straight tubular glands in the colonic mucosa.

colonic entrapment

see left colonic displacement (below).

colonic foreign body

foreign bodies, e.g. halter shanks, are found in the colon in horses, having passed the gastric sphincter and the ileocecal valve; quickly encrusted with salts.

colonic impaction

intractable constipation occurs in dogs and cats, primarily with obstruction by foreign material and secondarily when there is an obstruction to the normal passage of feces, including retention because of pain at defecation. See also colon impaction colic of horses.

colonic infarction

see thromboembolic colic.

colonic ischemia

deprivation of blood supply to all or part of the colon. See also intestinal torsion, intestinal strangulation, intestinal obstruction colic.

colonic obstruction

see colonic impaction (above), intestinal obstruction.

right dorsal colonic displacement

displacement of the right dorsal colon in the horse to the area between the right body wall and the cecum, in an anterior direction so that the pelvic flexure comes to lie against the diaphragm.

colonic rupture

occurs, apparently spontaneously, in mares at foaling, death occurring soon afterwards.

colonic torsion

in horses, see under equine colic. In cattle, torsion of the coiled colon is an acute obstruction with coils of gas-distended colon visible in the right flank and palpable per rectum.

colonic wash

fecal samples can be collected from reptiles by flushing the colon with saline through a catheter inserted through the cloaca and into the colon.
