Gall bladder torsion and rupture in a dog.

A 6-year-old desexed female German Shepherd dog was referred to the Murdoch University Veterinary Hospital for assessment and management of acute onset vomiting, diarrhoea, polydipsia and lethargy of 2 days duration. Surgical, microbiological and histological findings were consistent with necrotising cholecystitis secondary to gall bladder torsion, resulting in gall bladder rupture and secondary non-septic bile peritonitis. A chronic peritoneopleural perforation resulting from an abdominal cavity foreign body and congenital peritoneopericardial hernia were also present. The dog made a full recovery following cholecystectomy, foreign body removal, repair of the peritoneopleural perforation and peritoneopericardial herniorrhaphy. This is the first recorded case of gall bladder torsion in the dog.
