Abstract

Objective—To ultrasonographically measure the thickness of the individual wall layers of the duodenum, jejunum, and colon of dogs.

Animals—85 dogs with no clinical signs or ultrasonographic evidence of gastrointestinal tract disease.

Procedures—Total wall thickness and thickness of the mucosa, submucosa, muscularis, and serosa were measured ultrasonographically in the duodenum, jejunum, and colon of each dog.

Results—The mucosal layer was the thickest layer of the duodenum and jejunum. There was a significant difference in thickness of the mucosal layer between small and large dogs. Mean ± SD thickness of the mucosal layer of the duodenum for small, medium, and large dogs was 2.4 ± 0.5 mm, 2.6 ± 0.6 mm, and 2.8 ± 0.5 mm, respectively. Mean ± SD thickness of the mucosal layer of the jejunum for small, medium, and large dogs was 1.8 ± 0.4 mm, 2.0 ± 0.4 mm, and 2.2 ± 0.5 mm, respectively. The remaining wall layers of the duodenum and jejunum were similar in thickness, and there were no significant differences among small, medium, and large dogs. All layers contributed equally to the total colonic wall thickness. Mean ± SD thickness of the colonic wall for small, medium, and large dogs was 1.5 ± 0.3 mm, 1.4 ± 0.5 mm, and 1.6 ± 0.4 mm, respectively.

Conclusions and Clinical Relevance—Values for thickness of the wall layers of the duodenum, jejunum, and colon of dogs reported here may be useful for assessing gastrointestinal tract diseases primarily targeting a specific wall layer.

Abstract

Objective—To obtain ultrasonographic reference values for the thickness of the pancreas and the diameter of the pancreatic duct in clinically normal dogs.

Animals—242 adult dogs with no clinical signs of gastrointestinal tract disease.

Procedures—The maximum pancreatic thickness and the diameter of the pancreatic duct were recorded ultrasonographically at the level of the left lobe, body, and right lobe of the pancreas.

Results—Mean ± SD pancreatic thickness measurements were as follows: left lobe, 6.5 ± 1.7 mm (n = 214); body, 6.3 ± 1.6 mm (155); and right lobe, 8.1 ± 1.8 mm (239). The mean pancreatic duct diameter was 0.6 ± 0.2 mm (n = 42) in the left lobe and 0.7 ± 0.2 mm (213) in the right lobe. The right pancreatic duct was visible in 213/242 (88.0%) dogs, and the left pancreatic duct was visible in 41/242 (16.9%) dogs. However, the body was visible in only 16/242 (6.6%) dogs. Pancreatic thickness and diameter of the pancreatic duct significantly increased with body weight in all lobes, but age was not correlated with the measurements.

Conclusions and Clinical Relevance—Ultrasonographic reference values for the pancreas and pancreatic duct of dogs were determined. Results of this study indicated that the pancreatic duct was visible, especially in the right lobe of the pancreas. These values may be useful for the assessment of pancreatic abnormalities, such as chronic pancreatitis and exocrine pancreatic insufficiency.
