Ultrasonography of the gallbladder was performed in 3 groups of dogs: 30 clinically healthy dogs, 50 dogs with hepatobiliary disease, and 50 dogs with diseases other than hepatobiliary disease. The gallbladder was evaluated for the presence of sludge (echogenic material without acoustic shadowing). Maximal gallbladder length, width, height, and area were measured as well as the gallbladder wall thickness. The relative sludge area was calculated as the ratio of sludge area over gallbladder area on longitudinal images. No significant difference was found in the prevalence of gallbladder sludge among healthy dogs (53%), dogs with hepatobiliary diseases (62%), and dogs with other diseases (48%). The mean age of dogs with sludge was higher than the mean age of dogs without sludge in dogs with hepatobiliary disease and dogs with other diseases (p < 0.05). The mean relative sludge area did not differ significantly among the 3 groups. A trend to larger gallbladder dimensions in dogs with sludge compared to dogs without sludge was detected within the 3 groups. The gallbladder wall thickness was not different between dogs with and without sludge within the 3 groups. However, the gallbladder wall was more frequently isoechoic than hyperechoic to the liver in dogs with sludge than in dogs without sludge. The results of this study indicate that gallbladder sludge, in dogs, is not particularly associated with hepatobiliary disease and should be considered an incidental finding.
30只临床健康犬、50只患有肝胆疾病的犬和50只患有非肝胆疾病的犬。评估胆囊内是否存在胆泥（无声影的回声物质）。测量了胆囊的最大长度、宽度、高度和面积以及胆囊壁厚度。相对胆泥面积计算为纵向图像上胆泥面积与胆囊面积之比。在健康犬（53%）、患有肝胆疾病的犬（62%）和患有其他疾病的犬（48%）中，胆囊胆泥的患病率未发现显著差异。在患有肝胆疾病的犬和患有其他疾病的犬中，有胆泥的犬的平均年龄高于无胆泥的犬（p<0.05）。三组之间的平均相对胆泥面积无显著差异。在三组中均检测到，与无胆泥的犬相比，有胆泥的犬的胆囊尺寸有增大的趋势。三组中有胆泥和无胆泥的犬之间胆囊壁厚度无差异。然而，与无胆泥的犬相比，有胆泥的犬的胆囊壁与肝脏相比等回声的情况更常见。本研究结果表明，犬的胆囊胆泥与肝胆疾病并无特别关联，应视为偶然发现。
