Evaluation of the proventriculus:keel ratio for determining etiology of proventricular disease in parrots
Proventricular disease affecting psittacines may be due to a number of etiologies including Neuropathic Gastric Dilation disease, feared due to its presumptive viral etiology, potential contagion, and inevitably fatal outcome. The recently described proventriculus to keel ratio is a new objective method for determining normal vs. abnormal proventricular size from whole body lateral radiographs. In the study describing the new ratio, there were insufficient cases of proven proventricular disease to determine whether or not the ratio could differentiate between causes. Thus the aim of this study is to recruit cases of parrots with known proventricular disease, calculate the ratio and determine the discriminating capabilities.
Study Design:
Retrospective
Study Sample Size:
na
Inclusion criteria: Parrots that received whole body right lateral radiography and confirmation of proventricular disease by culture, surgery, necropsy or fluoroscopy. Any etiology resulting in proventricular disease will be included.
Exclusion Criteria:
No confirmation of proventricular disease.
Study Controls:
na
Samples:
Veterinarians will be asked to submit radiographs and diagnostic tests confirming proventricular disease (specific etiology). This discussion has been set up to allow VINners to upload their radiographs and diagnostic information.
If you can contribute to this study, please post a lateral radiograph of the parrot and all relevant proventricular diagnostic information in the discussion.
