Magnet-assisted endoscopic removal of ferromagnetic metallic gastric foreign bodies in 4 dogs.

OBJECTIVE: Describe presenting signs, diagnostic findings, and magnet-assisted endoscopic removal method of ferromagnetic gastric foreign bodies (FBs) in dogs. CLINICAL PRESENTATION: Four dogs presented with ingestion of sharp metallic FBs. The presence of gastric FBs was confirmed by abdominal radiography. RESULTS: In 3 cases, initial attempts at endoscopic removal were unsuccessful because of ingesta and fluid in the stomach. A magnet contained within a Roth net was introduced endoscopically. Magnet and attached objects were successfully removed from the stomach. In the fourth case, removal with a magnet was judged to be the most expedient method of removal because multiple metallic objects were present. CLINICAL RELEVANCE: An endoscopic technique was used for the removal of difficult-to-visualize or multiple metallic FBs. The use of this technique allows the removal of ferromagnetic gastric FBs without surgery or risk of complications associated with the passage of sharp material through the gastrointestinal (GI) tract.

Case Report: Septic Pericarditis With Achromobacter xyloxidans in an Immunosuppressed Dog.

A 5-year-old female spayed French Bulldog presented for anorexia and increased respiratory rate. On presentation, she was dyspneic with stridor and increased bronchovesicular sounds. Point-of-care ultrasound identified pericardial effusion. Thoracic radiographs identified pleural effusion, a wide cranial mediastinum, and multifocal unstructured interstitial pulmonary opacities. Bloodwork revealed a moderate leukocytosis characterized by a mature neutrophilia with a left shift, hypoalbuminemia, mildly increased alkaline phosphatase activity, and moderate hypokalemia. Thoracic CT findings revealed moderate pericardial and bilateral pleural effusion, mediastinal effusion, and moderate cranial mediastinal lymphadenopathy. Diagnostic thoracocentesis and pericardiocentesis revealed septic exudates with bacilli. Two days later, a median sternotomy and pericardiectomy were performed. Aerobic cultures of the effusions grew Achromobacter xylosoxidans ss deitrificans. The patient was treated with Amoxicillin-clavulanate and enrofloxacin for 12 weeks and clinically fully recovered. Achromobacter xylosoxidans has not been reported as a cause of purulent pericarditis and pyothorax in a dog. Uniquely, this patient is suspected of developing this infection secondary to immunosuppression.
