Objective-To identify clinical, laboratory, and ultrasonographic characteristics associated with gallbladder disease and rupture in dogs. Design-Retrospective case series. Animals-45 client-owned dogs. Procedures-Medical records of dogs with histologically confirmed gallbladder disease that had ultrasonographic evaluation were reviewed. Signalment, history, clinical signs, laboratory values, bacteriologic culture of bile, gallbladder status at surgery or necropsy (intact vs ruptured), histopathologic findings, radiographic findings, ultrasonographic findings, and outcome were analyzed. Results-The most common ultrasonographic findings were echogenic peritoneal fluid, thickened or laminated gallbladder wall, and echogenic reaction in the gallbladder fossa. Eighteen of 45 (40%) dogs had gallbladder rupture. Rupture was associated with histologic evidence of gallbladder necrosis, decreased serosal detail radiographically, and pericholecystic echogenic reaction, pericholecystic echogenic fluid, and generalized echogenic abdominal effusion ultrasonographically. Twenty-one of 45 (47%) dogs had mucocele, and 9 (43%) of those had gallbladder rupture. Eleven of 40 dogs had positive results of bacteriologic culture, and 5 of those had gallbladder rupture. Only 2 dogs had concurrent positive results of bacterial bile culture and gallbladder mucocele. Survival rate was 86% and not significantly related to presurgical bile leakage, positive results of bacterial culture, or mucocele. Conclusions and Clinical Relevance-Ultrasonographic findings of pericholecystic reaction, localized or generalized echogenic peritoneal fluid, or decreased radiographic peritoneal detail should raise the index of suspicion for gallbladder rupture. Mucocele or bacterial gallbladder infection was the most common concurrent finding in dogs with gallbladder rupture.
