Clinical use of uncovered balloon-expandable metallic biliary stents for treatment of extrahepatic biliary tract obstructions in cats and dogs: 11 cases (2012–2022)
Questions:
What was the primary objective of the study regarding uncovered balloon-expandable metallic biliary stents (BEMBS)? A. To compare the cost-effectiveness of BEMBS versus traditional surgical methods for EHBO. B. To describe the application of uncovered balloon-expandable metallic biliary stenting (BEMBS) for treatment of Extrahepatic Biliary Obstructions (EHBOs) and the outcomes for dogs and cats treated with this technique. C. To develop a new surgical technique for placing metallic biliary stents endoscopically. D. To analyze the long-term histological changes in bile ducts after BEMBS placement.
According to the study, which of the following is a key advantage of uncovered balloon-expandable metallic biliary stents (BEMBS) compared to traditional plastic stents for EHBO? A. They are easier to remove post-placement. B. They are less expensive to manufacture. C. They remain patent for longer periods of time and are less likely to develop biofilm. D. They require less specialized surgical equipment for deployment.
Which of the following was identified as a common challenge or complication associated with traditionalsurgical management of Extrahepatic Biliary Obstructions (EHBOs) in dogs and cats, as discussed in the sources? A. Decreased surgical time compared to stent placement. B. High success rates with minimal long-term complications. C. High mortality rates (7%-64% in dogs and 22%-100% in cats) and complications such as stent occlusion and biofilm formation. D. Inability to confirm bile duct patency during the procedure.
What was the median bile-duct patency duration observed for dogs and cats, respectively, with long-term follow-up available in the study by Bergen, Travis, and Pike (2023)? A. Cats: 70.5 days; Dogs: 190 days. B. Cats: 1.8-5.5 months; Dogs: 3.4-9.4 months. C. Cats: 446 days; Dogs: 650.5 days. D. Cats: 48 hours; Dogs: 62 days.
