Abstract

<h4>Background</h4>Abdominal ultrasound is frequently used to detect non-perforated gastroduodenal ulcers in dogs. Studies assessing the diagnostic utility of abdominal ultrasound for the detection of non-perforated gastroduodenal ulcers have yielded mixed results. No studies to date have investigated the effects of patient bodyweight, breed, sex, age, ulcer aetiology (neoplastic or inflammatory) or location on the diagnostic accuracy of abdominal ultrasound.<h4>Methods</h4>Retrospective, multicentre study to evaluate the diagnostic utility of abdominal ultrasonography for the diagnosis of non-perforated gastroduodenal ulceration in dogs.<h4>Results</h4>Sixty-one dogs met the inclusion criteria. Ulcers were detected during ultrasound examination in 18 of 61 dogs, yielding a sensitivity of 29.5% (95% confidence interval 18.8%-42.7%). Ulcers in the pyloric region were detected more frequently than those in the duodenum; however, location was not significantly associated with the ability of ultrasound to detect lesions (p = 0.41). No associations were identified between the ability of ultrasound to detect an ulcer and patient bodyweight (p = 0.45), breed (p = 0.98), sex (p = 0.90), age (p = 0.94), and neoplastic versus inflammatory nature of ulcerative lesions (p = 0.93).<h4>Conclusion</h4>The diagnostic utility of ultrasound as the sole modality for the detection of non-perforated gastroduodenal mucosal ulceration is poor. The authors therefore recommend the use of additional modalities when ulcerative lesions are suspected.
