Liver lobe torsion is an uncommon condition of unknown etiology that has been identified in dogs, cats, horses, sows, rabbits, otters, and humans.1–23 In dogs, clinical signs are typically nonspecific and surgical findings and outcome are variable.2,3,11,16–18,23 Clinical signs in affected dogs may be acute or chronic and most often consist of signs of abdominal pain, vomiting, anorexia, lethargy, collapse, and sudden death.
A search of the veterinary literature yielded reports of only 25 cases of LLT involving various species1–23 and only 11 cases involving dogs. 2,3,11,14–17,23 Dogs with LLT in these previous reports were typically middle-aged to older and of large or medium body size, with no sex predilection evident. An inciting cause for LLT has not been determined, nor have predisposing factors been identified. Despite anatomic variations in the affected species, the left lateral lobe is reported as the most commonly torsed liver lobe.8,14,17,19 The predisposition of this lobe to torsion is attributed to its relatively large size, greater mobility, and relative separation from the other lobes.17
Clinical signs, results of diagnostic testing, treatment, and outcome of dogs with LLT described in previous reports have varied substantially. For this reason, more information about affected dogs would be useful. The purpose of the study reported here was to determine history, results of diagnostic testing, surgical findings, complications, and outcome for dogs with LLT.
