Dimensional ultrasonographic relationship of the right lobe of pancreas withassociated anatomic landmarks in clinically normal dogs

[摘要] References(22)The purpose of this prospective study was to establish the ultrasonographiccharacteristics of the dimension of the right pancreatic lobe with that of the associatedanatomic landmarks in healthy dogs. Ultrasonographic examinations were performed on 25dogs. The thickness of the right pancreatic lobe was compared with that of mural thicknessof duodenum, diameter of duodenum, pancreatic duct, abdominal aorta, portal vein, caudalvena cava, and length and width of the right kidney and right adrenal gland. Thecorrelation between each pancreatic parameter and the dimensions of the anatomicallandmarks were assessed using linear regression analysis and Pearson’s correlationcoefficient (r) test. Significant, but weak linear correlations were observed betweenthickness of right pancreatic lobe with that of duodenum mural thickness (r=0.605,R2=0.339, P=0.001); duodenum diameter (r=0.573,R2=0.299, P=0.003); and right adrenal gland length (r=0.508,R2=0.052, P=0.01). There was no significant dimensionalrelationship with other selected anatomic landmarks. The ratio between the thickness ofright pancreatic lobe and the mural thickness of duodenum, diameter of duodenum and lengthof right adrenal gland were 2.88 ± 0.53, 1.27 ± 0.27 and 0.81 ± 0.15, respectively.Calculating the ratio of thickness of the right pancreatic lobe with the dimension ofsignificantly correlated anatomic landmarks is a useful and simple method for evaluatingthe size of the right pancreatic lobe in dogs in clinical practice.
