Equine Colic Types

Large colon lesions

Predispositions to disease

Minimal fixation allows movement – colonic torsions and displacements are common

Gas production during microbial digestion may cause colic (gas distension; displacement)

Hairpin turns and changes in diameter create sites prone to impaction

 

 

 

Large intestinal disorders are characterized by:

  1. Gas distension : microbes keep producing it even if physical obstruction
  2. Mild-severe colic : depends upon amount of gas distension
  3. Bloat : can see rib cage and flank distension
  4. Decreased fecal production

 

Two types of large colon disorders can reflux: nephrosplenic entrapments and small colon impactions. We believe the colon lesions areĀ  pinching the duodenum shut, creating a secondary SI obstruction.
