Plain-English summary
A group of 17 dogs and 5 cats with confirmed stomach tumors underwent both ultrasound and endoscopy to see which method was better at finding these issues. The endoscopy was much more effective, identifying 95% of the tumors, while the ultrasound only found 50%. Most of the missed tumors were lymphomas, particularly in cats. While endoscopy is the best way to diagnose stomach tumors, ultrasound can still help raise suspicion and is less invasive.

Abstract
OBJECTIVE: To compare sonographic and endoscopic findings in a group of dogs and cats with histologically confirmed gastric neoplasia. METHODS: Retrospective analysis of cases with concurrent abdominal ultrasound and endoscopy to evaluate the presence of gastric wall abnormalities, location and tumour appearance between the two examinations. Sonographic findings of the small intestines, liver, spleen and lymph nodes were recorded. Comparison of the findings from each test and assessment of predictive characteristics for neoplasia was evaluated. RESULTS: In total 17 dogs and 5 cats were included, Sonography identified 50% and endoscopy identified 95% of all gastric neoplasms. Lymphoma was the most commonly missed tumour by sonography. There was sonographic and endoscopic tumour location agreement in 36% of cases (Cohen's kappa = 0 · 25). Animals with sonographically normal small intestines had a statistically greater probability of gastric neoplasia (P = 0 · 035). All cats had lymphoma (P < 0 · 001). CLINICAL SIGNIFICANCE: Sonography and endoscopy are useful for the diagnosis of gastric neoplasia. Endoscopy is more accurate in identifying gastric neoplasia; however, sonography can raise the clinical suspicion for gastric neoplasia and may provide a less invasive means of gathering information before endoscopy. Intraluminal gastric gas or fluid may limit diagnostic capabilities of sonographic evaluation.
