Aissi A., Prevalence of gallbladder disorders in dogs by ultrasonography, Onl J Vet Res., (12):846-850, 2021. Author describes ultrasonography of gallbladders in 93 dogs with hepatobiliary disease by 3.5-5 MHZ convex transducer. Dogs were fasted 12h and shaved from 11th rib to umbilicus on either side of ventral abdomen and tested in dorsal recumbency. The liver was examined by scanning dorsal or lateral caudal xiphi-sternum for longitudinal and transverse images of gallbladder. Ultrasound images were evaluated for hepatic echogenicity, vascularity, gallbladder sludge, mucocele, polyps and cholecystitis. Gallbladder sludge was found in 34 (37%) dogs as echogenic bile or sediment without acoustic shadowing with one type characterized by a clear line of interface between the echogenic sludge and anechoic bile, and another as accumulation of echogenic materials. The gallbladder wall was mostly isoechoic. Mucocele appeared as immobile gravity dependent stellate or finely striated bile in 3 animals (3.22%). Cholecystitis was found in 23 dogs (25.8%) characterized by > 3mm thickened gallbladder wall. We found polyp only in 1 dog appearing as echogenic bile or sediment amassed to gallbladder wall. Images of ultrasounds are provided.

Key Words: Ultrasound, gallbladder, canine, sludge, cholecystitis.
