Bronchoscopic findings in dogs with bronchial vegetal foreign bodies: 84 cases (2010-2020).

OBJECTIVES: To describe endoscopic findings, foreign body location, success rate of removal and complications in dogs with bronchial vegetal foreign bodies. MATERIALS AND METHODS: The current study retrospectively evaluated the case records of dogs diagnosed with bronchial vegetal foreign bodies at a veterinary hospital centre between January 2010 and April 2020. Information retrieved included breed, sex, age, bodyweight, the season of presentation, presentation and duration of clinical signs, previous removal attempts performed by the referring veterinarian, foreign body location and endoscopic and imaging findings. RESULTS: Eighty-four cases were included. Fifty-nine dogs (70%) presented during spring and summer. Cough (77 of 84; 92%) and fever (15 of 84; 18%) were the main clinical signs. One to 10 bronchial vegetal foreign bodies were removed from each dog. Purulent exudate was observed in the ventral larynx, trachea and bronchi in 49 (65%), 61 (81%) and 71 (95%) dogs, respectively. In most cases, only the barbules of the vegetal foreign bodies were initially observed during endoscopy. The presence of large bronchial nodules or an irregular mucosal surface was a frequent finding (62 of 75; 83%). Mild bleeding was the main complication (58 of 75; 77%) of endoscopic removal, which was successful in 67 of the 84 (80%) cases. CLINICAL SIGNIFICANCE: Mucosal nodules associated with purulent material within the airways are frequent endoscopic findings in dogs with bronchial vegetal foreign bodies. Bronchoscopy is a relatively safe and useful technique for diagnosis and treatment of bronchial vegetal foreign bodies in dogs.

Effect of clinical signs, endocrinopathies, timing of surgery, hyperlipidemia, and hyperbilirubinemia on outcome in dogs with gallbladder mucocele.

Gallbladder mucocele (GBM) is a common extra-hepatic biliary syndrome in dogs with death rates ranging from 7 to 45%. Therefore, the aim of this study was to identify the association of survival with variables that could be utilized to improve clinical decisions. A total of 1194 dogs with a gross and histopathological diagnosis of GBM were included from 41 veterinary referral hospitals in this retrospective study. Dogs with GBM that demonstrated abnormal clinical signs had significantly greater odds of death than subclinical dogs in a univariable analysis (OR, 4.2; 95% CI, 2.14-8.23; P<0.001). The multivariable model indicated that categorical variables including owner recognition of jaundice (OR, 2.12; 95% CI, 1.19-3.77; P=0.011), concurrent hyperadrenocorticism (OR 1.94; 95% CI, 1.08-3.47; P=0.026), and Pomeranian breed (OR, 2.46; 95% CI 1.10-5.50; P=0.029) were associated with increased odds of death, and vomiting was associated with decreased odds of death (OR, 0.48; 95% CI, 0.30-0.72; P=0.001). Continuous variables in the multivariable model, total serum/plasma bilirubin concentration (OR, 1.03; 95% CI, 1.01-1.04; P<0.001) and age (OR, 1.17; 95% CI, 1.08-1.26; P<0.001), were associated with increased odds of death. The clinical utility of total serum/plasma bilirubin concentration as a biomarker to predict death was poor with a sensitivity of 0.61 (95% CI, 0.54-0.69) and a specificity of 0.63 (95% CI, 0.59-0.66). This study identified several prognostic variables in dogs with GBM including total serum/plasma bilirubin concentration, age, clinical signs, concurrent hyperadrenocorticism, and the Pomeranian breed. The presence of hypothyroidism or diabetes mellitus did not impact outcome in this study.
