ABSTRACT
OBJECTIVE:
To describe the application of uncovered balloon-expandable metallic biliary stents for treatment of extrahepatic biliary obstructions (EHBOs) and the outcomes for dogs and cats treated for EHBO with this technique. STUDYDESIGN:
Retrospective single institutional study. ANIMALS Eight dogs and three cats treated at the Veterinary Specialty Hospital of San Diego for EHBO between January 2012 and February 2022.METHODS:
Data collected from the medical records included signalment, presenting complaint, laboratory and imaging findings, surgical findings, hospitalization time, complications, and follow-up information.RESULTS:
Median duration of short-term follow up was 16 days (6-45 days). Improved biochemical abnormalities and resolution of clinical signs were recorded in 10/11 cases. Two dogs died within 2 weeks of surgery. One dog developed systemic inflammatory response syndrome 5 days postoperatively and was euthanized; the cause of death in the second case was unknown. Long-term follow up was available in seven cases, with a median duration of 307.5 days (62-2268 days). Bile-duct patency was maintained for at least 356-622 days (median 446 days) in three cats and 62-2268 days (median 650.5 days) in four dogs with long-term follow up available. One cat had recurrent obstruction with choledocholiths 446 days postoperatively. One stent was removed 614 days postoperatively due to recurrent cholangiohepatitis.CONCLUSION:
Uncovered balloon-expandable metallic biliary stents were placed successfully and relieved EHBO in all cases that survived to discharge. CLINICALSIGNIFICANCE:
Use of uncovered balloon-expandable metallic biliary stents should be considered as an alternative to temporary choledochal luminal stenting or cholecystoenterostomy to manage EHBO.
