Abstract
The present work on equine abdominal ultrasonography was conducted in two phases. In standardization phase, detailed abdominal ultrasonographic scan was performed on native 10 adult (5horses and 5 mules) healthy equines of either sex to develop baseline topographical data of various organs. In this phase, the organs of right and left hemi-abdomen were topographically located, their echo-architecture was described. A baseline data of landmarks for locating different abdominal organs was elucidated. The sonographic calliper measurements of different organs were generated along with dynamic parameters of alimentary tract to help delineate the pathology. In clinical application phase, 14 clinical cases of equines suspected for abdominal disorders were subjected to ultrasonography for assisting the diagnosis. Colonic impactions were imaged as hyperechoic intraluminal structure casting a strong acoustic shadow. Bull’s eye or sandwich like appearance of intestinal loops was characteristic of intussusceptions and can be imaged transabdominally. Descending colon obstructions were imaged as a large hyperechoic intraluminal masses casting a strong acoustic shadow with loss of normal sacculations and peristaltic movement of descending colon. In case of peritonitis the peritoneum could be imaged as thin echogenic layer with lot of peritoneal fluid present inside the abdominal cavity with marked thickening of jejunal wall. It was concluded that thorough clinical investigation combined with ultrasonography was found to be an important diagnostic imaging aid for diagnosing different abdominal disorders in equines and equips the surgeon/clinician to identify the exact etiology, which helps reach at an accurate diagnosis and formulate a precise and efficient therapeutic plan.
