Abstract

The purpose of this study is to determine the changes of ultrasonographic appearance of stomach, pylorus and duodenum in relation to food intake and administration of contrast medium in dogs. Ultrasonograms were obtained with 5.0MHz sector transducer. After placing the dogs in dorsal recumbency, scanning was performed at the 8th intercostal space. The mean inner diameter of stomach immediately after food intake, 2, 4 and 6 hours was 47.9, 51.5, 46.8 and 40.6mm, respectively. The diameter of pylorus immediately after food intake, 2, 4 and 6 hours was 7.4, 9.7, 8.9 and 6.0mm, respectively(p<0.01). The diameter of duodenum immediately after food intake 2, 4 and 6 hours was 12.5, 7.9, 11.9 and 11.8mm, respectively(p<0.01). Before administration of contrast medium, the mean inner diameter of stomach, pylorus and duodenum was 38.6, 7.2 and 9.5mm, respectively. After administration of contrast medium, the diameters of stomach, pylorus and duodenum was 42.8, 7.7 and 9.9mm, respectively. It may be concluded that the ultrasonographic values determined in this study can be used as references for the diagnosis of gastrointestinal disease in dogs.
