Clinical, laboratory and ultrasonographic findings in Egyptian buffalo (Bubalus bubalis) with caecal and colonic dilatation

The present study was conducted to describe the clinical, laboratory and ultrasonographic findings of caecal and colonic dilatation in Egyptian buffalo (Bubalus bubalis). A total number of forty buffaloes were included in the study and divided into two groups: control group (n = 20) and diseased group (n = 20). Diseased buffalo were admitted to the Veterinary Teaching Hospital at Assiut University-Egypt. Each of the diseased animals was subjected to clinical, rectal, laboratory and ultrasonographic examinations. Clinically, buffalo with dilated caecum/colon showed reduced appetite, distended right abdomen, abdominal pain and tensed abdomen. Rectal examination indicated empty rectum with the presence of mucus and dilated loop of caecum and/or colon. Buffalo with dilated caecum/colon showed significant (P < 0.05) hypoproteinemia and hypoalbuminemia with significant (P < 0.05) increase in blood serum activities of aspartate aminotransferase (AST) and alkaline phosphatase (ALK). Ultrasonographically, the dilated caecum and proximal loop of colon occupied the last right three intercostal space (ICSs) particularly their ventral part, intertangled with the liver dorsally in these ICSs. Dilated colon did not hinder the visibility of the liver. The dilated caecum/colon also filled the whole right flank region, with hiding of right kidney, loops and peristaltic movement of the small intestines. The closest wall of the dilated caecum and proximal loop of the colon was imaged as thick semi-circular echogenic line. The furthest wall and contents of dilated caecum/colon were not imaged. In conclusion, buffalo with caecal and/or colonic dilatation have non-specific clinical and laboratory findings; however the affected animals show characteristic ultrasonographic findings.
