🔍 Key Findings
Mortality rate: 36% (12/33)
Cholecystectomy performed: 94% of dogs (31/33)
New significant prognostic factors for survival:
- Hyperbilirubinemia (p = .049) — threshold = 60.5 μmol/L
- Use of vasopressors (p = .002)
- Renal dysfunction postoperatively (p = .008)
- Number of postoperative complications (p = .005)
Multivariate model: Total bilirubin and number of complications best predicted survival
Septic vs nonseptic effusion: No significant difference in survival
Diagnostic imaging: Ultrasound sensitivity for extrahepatic biliary rupture = 38%
Most cultured pathogen: E. coli (80% of septic cases)
