In the present study a total number of 26 dogs and 16 cats have been examined and diagnosed ultrasonographically with liver and gallbladder surgical affections. In dogs, it was found that the most liver and gallbladder affections were liver tumors 16 cases out of 26 affected dogs with an incidence rate of 61.5%. in the second level were cholecystit...

In Veterinary Medicine, diseases restricted to the gallbladder (GB) are uncommon in dogs. The histopathological examination of GB is considered the gold standard. However, abdominal ultrasound examination is increasingly included in the veterinary clinical routine, as it allows changes in previously underdiagnosed GB to have a more accurate diagnos...

Outro aspecto ultrassonográfico clássico da mucocele da VB é quando apresenta aparência macroscópica semelhante ao interior da fruta kiwi (JAFFEY et al., 2022;SAMY et al., 2014) quando cortada transversalmente. Características de padrão estriado, estrelar ou de kiwi podem ser observadas nas figuras 2, 3 e 4, respectivamente. ...

A lama biliar e a mucocele biliar são afecções caracterizadas por aumento da viscosidade e densidade da bile, tornando-a semi-sólida. Na lama biliar, este conteúdo é móvel no lume da vesícula biliar (VB), enquanto que na mucocele é imóvel devido sua aderência à parede da vesícula, comprometendo o fluxo biliar e integridade desta. Exame ultrassonográfico é comumente realizado para auxiliar no diagnóstico dessas afecções em caninos e felinos domésticos. Este estudo objetivou descrever sobre aspectos ultrassonográficos da lama biliar e da mucocele biliar em cães e gatos, norteados por uma abordagem sobre aspectos morfofisiológicos e clínicos envolvidos com a formação, evolução e relação destas afecções com outras doenças nesses animais. Para isto, foi realizada uma revisão das descrições em livros, dissertações, teses e periódicos indexados no Scielo, Scopus ou Web of Science, o que favoreceu para ser concuído que a ultrassonografia se destaca como exame essencial e de grande serventia para caracterizar a lama biliar e a mucocele na VB, auxiliando significativamente no diagnóstico destas enfermidades, assim como de outras concomitantes doenças no corpo nas quais a lama e a mucocele biliar possam estar relacionadas.

These findings were agreement with Samy et al., 2014. The margin of l dissimilar to that of normal one almost rounded in shape. ...
... Earlier studies have reported no sex predilection in dogs for primary hepatobiliary tumors (Trigo et al., 1982) and chronic hepatitis (Strombeck et al., 1988). Samy et al.

(1996) reported that females were more commonly affected with chronic hepatitis. ...

A total of 109 dogs were screened, of which 30 dogs with hepatobiliary affections were included for this study. Common clinical findings in hepatobiliary disease were intermittent anorexia, lethargy, weight loss, and vomiting. Ultrasonographic examination showed reduced parenchymal echogenicity with prominent visualization of hepatic vasculature in acute hepatitis; hyperechoic bright liver with normal size in chronic hepatitis and bright and small liver with irregular margins in hepatic cirrhosis. Hepatomegaly on ultrasonography appeared as enlarged liver with rounded margins. Further ascites, hepatic cyst, hepatic neoplasia, cholelith, and gall bladder polyp/mass were diagnosed by using ultrasonography. Based on present findings, it was concluded that ultrasonography could be best exploited in hepatobiliary disorders.
