“…Because of reflection of the ultrasound waves at the soft tissue-air interface, the intestinal contents and the intestinal wall furthest from the transducer cannot be visualised. In contrast with results in dogs [42], there is no difference between the diameter of most of the small intestine before and after feeding in cattle. This uniformity is probably because the forestomachs constitute a feed reservoir and ingesta pass along the intestine continuously, independent of feed intake, and without changes in the diameter of the intestinal lumen, which would be measurable by ultrasonography.…”

Ultrasonography is an ideal diagnostic tool for the investigation of bovine gastrointestinal disorders, the most common of which are traumatic reticuloperitonitis, left and right displacement of the abomasum, ileus of the small intestine, and dilatation and displacement of the cecum. An ultrasonographic examination is performed on nonsedated, standing cattle using a 3.5 MHz to 5.0 linear or convex transducer. When a tentative diagnosis has been made based on the clinical findings, often only the region in question is examined. For example, in cases with suspected traumatic reticuloperitonitis, the examination is performed in the sternal and parasternal regions, and in cattle suspected of having cholestasis, only the costal part of the abdominal wall on the right side is examined. Even experienced clinicians may not be able to pinpoint the organ affected and make a diagnosis in patients in which abdominal disease is suspected, however. In such cases, both sides of the abdomen are examined. Normally, the reticulum,1,2 spleen,1-4 rumen,2 and parts of the abomasum5,6 are seen on the left side, and the liver,7-9 omasum,10,11 parts of the abomasum,5,6 small intestine,12,13 large intestine,14,15 and right kidney16 are seen on the right. The uterus may be seen on either side depending on the stage of pregnancy. This article describes the ultrasonographic techniques used for examination of the reticulum, rumen, omasum, abomasum, small intestine, and large intestine. The normal findings are presented followed by a description of the most important diseases of these organs.Ultrasonography of the gastrointestinal tract in cattle AbstractUltrasonography is an ideal diagnostic tool for investigating gastrointestinal disorders in cattle. It is performed on standing non-sedated cattle using a 3.5 to 5.0 MHz linear or convex transducer. In animals with traumatic reticuloperitonitis, inflammatory fibrinous changes and abscesses can be imaged. Ultrasonography can be used to assess the size, position and contents of the abomasum. In left displacement of the abomasum, the abomasum is seen

“…The mean pyrolic contractions of saline and soup groups before feeding were 4.19 ± 1.30, 4.82 ± 0.65 per min and overall contractions during feeding were 4.66 ± 1.37, 5.13 ± 1.71 per min which is similar to the result of 4-5 frequency per min by Penninck's report [19].…”

“…In veterinary clinical medicine, ultrasonographic studies of canine stomach were mainly on the normal and abnormal morphology rather than the functional analysis [1,3,20,21]. But recent technical developments enable one to evaluate gastroduodenal motility by using ultrasonography, which is simple and noninvasive.…”

ABSTRACT. For the evaluation of canine gastric motility with ultrasonography, contraction number of pyloric antrum and gastric emptying time (GET) by area and volume method developed by Bolondi et al.'s method were studied in 14 dogs. All experimental dogs were administered with saline and soup solution (10 ml/kg, B.W.). The mean values of contraction number of pyloric antrum in saline and soup group were 4.19 ± 1.30/min and 4.82 ± 0.65/min before feeding, and overall mean values were 4.66 ± 1.37/min and 5.13 ± 1.71/ min, respectively. The mean values of the GET by area and volume method were 36.73 ± 11.27, 40.00 ± 8.87 min in saline group and 61.35 ± 17.58, 59.11 ± 14.46 min in soup group. In the GET in saline and soup groups, there was no significant difference between the area and volume method (p>0.05). Therefore, Bolondi et al.'s method by ultrasound can be used to evaluate the antropyloric motility and gastric emptying time with area and volume methods. The area method is easier to determine the GET than the volume method, but the latter is more accurate.

“…The reference range of duodenal wall thickness determined at the descending duodenal wall of 5 healthy beagles was 4.4 ± 0.2 mm (mean ± SD). In a previous study, normal values for small intestinal wall thickness measured by transabdominal ultrasonography were reported to be between 2 and 3 mm [6]. The descending duodenal wall thickness of dogs No.…”

ABSTRACT. Alimentary lymphoma was evaluated endoscopically in 7 dogs and a histopathological examination was made to detect the origin of neoplastic lymphocytes in 5 dogs. A solitary mass in the rectum (1 case), irregular cobblestone appearance in the duodenum (4 cases) and a moderate irregular appearance resembling lymphocytic-plasmacytic enteritis (2 cases) were endoscopically detected. Endoscopic ultrasonography demonstrated increased thickness of the duodenal wall in 2 cases examined. Neoplastic lymphocytes of alimentary lymphoma proved to originate in T cells in all 5 cases examined by immunohistochemical analysis. KEY WORDS: alimentary lymphoma, canine, endoscopy.
