Gastric dilation-volvulus in dogs attending UK emergency-care veterinary practices: prevalence, risk factors and survival (original) (raw)

2017, Journal of Small Animal Practice

To report prevalence, risk factors and clinical outcomes for presumptive gastric dilation-volvulus diagnosed among an emergency-care population of UK dogs. Methods: Cross-sectional study design using emergency-care veterinary clinical records from the VetCompass TM Programme spanning September 1 st , 2012 to February 28 th , 2014. Risk factor analysis using multivariable logistic regression modelling. Results: The study population comprised 77,088 dogs attending 50 Vets Now clinics. Overall, 492 dogs had presumptive gastric dilation-volvulus diagnoses giving a prevalence of 0.64% (95%CI: 0.58%-0.70%). Compared with crossbred dogs, breeds with the highest odds ratios for diagnosis of presumptive gastric dilation-volvulus were the great Dane (OR: 114.3, 95% CI 55.1-237.1, P < 0.001), akita (OR: 84.4, 95% CI 33.6-211.9, P < 0.001) and dogue de Bordeaux (OR: 82.9, 95% CI 39.0-176.3, P < 0.001). Odds increased as dogs aged up to years and neutered male dogs had 1.3 (95% CI 1.0-1.8, P = 0.041) times the odds compared with entire females. Of presumptive gastric dilation-volvulus cases that presented alive, 49.7% survived to discharge but 79.3% of surgical cases survived to discharge. Clinical importance: Approximately 80% of surgically managed cases survived to discharge. Certain large breeds were highly predisposed.
