A Japanese Black calf six and a half months old showed signs of anorexia and constipation for eight days. It failed to respond to any medical treatment during this period. The right sublumbar fossa was mildly distended. A resonant ping was audible by simultaneous auscultation and percussion over the whole right flank on the sixth day of illness.
A tentative diagnosis of cecal volvulus was made. laparotomy was performed through the right flank under local anesthesia. Manual examination of the abdominal cavity detected the distended and displaced cecum filled with a large amount of gas and gastric juice, and adhesions of the omentum to the intestinal wall around the ileocecocolic junction.
As the site of adhesion was thickened with proliferated connective tissue and the intestinal lumen narrowed at this site, the cecum and a proximal part of the colon were resected and then end-to-end anastomosis was made between the ileum and the colon.
Postoperative recovery was uneventful with defecation on the day after operation and the appetite resumed gradually. During the postoperative period of four and a half months, the serum magnesium level was high temporarily and returned later to a normal one.
