Ingestion of multiple magnets by a dog

Abstract

Letters magnet was removed from the stomach via a single gastrotomy incision; the necrotic area was resected and then closed with a two-layer inverting seromuscular pattern (3-0 polyglyconate). The dog recovered well from surgery without any postoperative complications. In order to minimise the risk of gastrointestinal complications caused by magnetic attraction it is suggested that if multiple, small, metallic foreign bodies are seen on abdominal radiography these should be monitored frequently with serial radiography. If they are found to be nonprogressive or there are signs suggestive of peritonitis, an exploratory laparotomy should be performed immediately (Kiefer and others 2010).

Laparoscopic removal of a large abdominal foreign body granuloma using single incision laparoscopic surgery (SILS) and extraction bag in a cheetah (Acinonyx jubatus)

“…Various types of abdominal FB have been reported in dogs, which usually remain confined to the GIT lumen (Larson and Madsen 2010, Becker 2011, Creedy and Bates 2011, Battisti and others 2012, Allman and Pastori 2013, Nair and others 2013, Kassem and others 2014). GIT-related FBs are typically removed surgically (Kassem and others 2014) or less commonly endoscopically (Shin and others 2010, Baranidharan and others 2013).…”

“…Reports on gastrointestinal tract (GIT) foreign bodies (FB) in dogs are common and are typically associated with related clinical signs; conversely, reports in cats are rare and usually limited to linear FB. Various types of abdominal FB have been reported in dogs, which usually remain confined to the GIT lumen (Larson and Madsen 2010, Becker 2011, Creedy and Bates 2011, Battisti and others 2012, Allman and Pastori 2013, Nair and others 2013, Kassem and others 2014). GIT‐related FBs are typically removed surgically (Kassem and others 2014) or less commonly endoscopically (Shin and others 2010, Baranidharan and others 2013).…”

Successful medical management of multiple ‘Rattle’ magnet ingestion in a dog

“…In the present case, the dog’s main clinical sign was vomiting, which appears to be the most common clinical sign reported 1–4 8…”

“…Multiple magnets, or a magnet ingested with other metallic foreign bodies, can cause attraction across loops of bowel 2 3. One possible explanation for perforation as a consequence of attraction is the continuous pressure on the bowel wall leading to complete ischaemia, necrosis and tissue breakdown with ulcerations through submucosa and muscularis propria, resulting in perforation 3 8…”

“…There are five reported cases of magnet ingestion in the veterinary literature 1–4 8. In a case report,1 a dog developed septic peritonitis secondary to gastric and colonic perforations from ingestion of multiple magnets.…”
