The medical records of 41 dogs and four cats with either surgical or postmortem confirmation of extrahepatic biliary tract obstruction were reviewed. Clinical signs of icterus, vomiting, anorexia, or a combination of these signs were exhibited by 100% of cases. Elevated serum bilirubin was documented in 37 of 41 dogs and two of four cats (86.6%). The predominant, underlying, pathological process was extraluminal obstruction of the biliary tract due to pancreatitis (19 of 45 cases; 42.2%) or neoplasia (11 of 45 cases; 24.4%). Biliary tract surgery was performed in 29 cases, of which 12 (41.3%) recovered. Animals diagnosed with extrahepatic biliary tract obstruction had a relatively good long-term prognosis, provided they were not compromised substantially due to severe necrotizing pancreatitis or neoplasia.
Sacral fractures have not been described well in dogs. The records of 32 dogs diagnosed with sacral fractures were evaluated for neurologic deficits at presentation and discharge. Follow-up was in the form of telephone survey or physical examination at recheck. A score was assigned for each dog at presentation, discharge, and follow-up (0 for normal, 1 for minor deficits, and 2 for major deficits). Fractures located lateral to the sacral foramina were called abaxial, and those medial to the sacral foramina were called axial. Axial fractures had significantly more severe deficits at presentation (p = 0.00017) and discharge (p = 0.03063), but not at follow-up. Neurologic status did not improve significantly during hospitalization in either fracture group, but had improved significantly at follow-up.
Recurrent pyogenic cholangitis is a chronic infection characterized by intrahepatic biliary stones and strictures. Escherichia coli is the commonest infecting organism. This disease is very common in East Asia but infrequent in Western countries, and few reports have been published in European series. The therapeutic approach for hepatolithiasis is highly individual and includes antibiotic therapy, endoscopic and percutaneous biliary drainage with stone removal and dilation of strictures, surgical resection of affected liver segments and liver transplantation. We report two cases of RCP in Chinese patients treated with liver transplantation at our center out of the 34 published in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
