A 5-year old Japanese Black female cattle was examined because of abdominal pain and anorexia. The rectal temprature was 39.5°C. A tympanic sound was found in the right paralumber fossa. During rectal palpation, abdominal organs could be palpable as a large baloon in the abdominal cavity. Therefore, a right flank lapalotomy was performed. A 20- to 25-cm incision was made in the right paralumbar fossa. The flank laparotomy revealed the distention of cecum and a disk-like colon and three masses of fatnecrose. The laparotomy was explored to remove the one of the three masses and to detect possible complications. The flank incision was closed in a routine manner. One of the three masses of fatnecrose, which was found to constricting the disk-like colon, was surgically removed with care and there was an indication of cecotomy and colotomy. Thereafter appetite steadily improved and the patient recovered. We carefully considered the course of the operation. We should make a 30- to 40-cm width incision in the paralumber fossa. A decision was needed on the choice of which fatnecrose mass should be removed and on the matter of removing it. The removed mass was attached to the disk-like colon remarkably, and if it was removed uncarefully, the colon may have ruptured. It is important to perform the operatiom very carefully.
