キーワード : canine ileus, abdominal ultrasonography

　The ultrasonic examination by a real time scanning system (3.5 MHz, linear type) and X-ray study of the abdomen were performed on the dogs, which had been caused to have obstructions of the upper or lower intestine. The abdomens of the controls were incised and the intestine were exposed and then reinserted in place. Observations by these methods were made seven times (1 prior to the operation　2 after 6 hours 3 after 12 hours　4 after 18 hours　5　after 24 hours 6 after 36 hours　7 after 48 hours).
　The ultrasonographic examination demonstrated a fluid filled bowel six hours after operation at a high rate in the lower and upper obstruction groups, while the air fluid levels and abnormal gas could be detected on the X-ray films less frequently. The echograms of the fluid filled bowel, the air fluid levels and the intestinal gas on the X-ray films increased progressively. Therefore, abdominal ultrasonography is thought to be one of the best methods for diagnosis of the ileus.
