feeding status of the horse ( fasted versus fed ) affects gastrointestinal motility . Alpha 2 adrenoreceptor agonists will decrease gastrointestinal motility and should be avoided if at all possible prior to the sonographic examination of the abdomen if GI motility is being assessed .
Abnormal Findings in Horses with Colic Herniation / Displacement
Abnormal positioning of the gastrointestinal viscera is difficult to diagnose ultrasonographically , unless the viscera are displaced into the scrotum , thoracic cavity or into an umbilical hernia .
Small intestine within scrotal sac
Displacement of the gastrointestinal viscera into the thoracic cavity through a diaphragmatic hernia can usually be diagnosed ultrasonographically by scanning the affected side of the thorax and cranial abdomen and looking for the rent in the diaphragm , as displacement of the overlying lung by the herniated viscera occurs . The approximate size of the diaphragmatic hernia can be estimated and the gastrointestinal viscera evaluated for the degree of bowel compromise . However , a diaphragmatic hernia could be missed ultrasonographically if it was located in the center of the diaphragm and the herniated viscera were not in contact with the thoracic wall .
