Objective: To evaluate the differential diagnostic value of the gastrointestinal ultrasound contrast filling method in distinguishing gastric tumors from gastric ulcers in elderly patients.
Methods: We retrospectively analyzed 274 elderly patients diagnosed with gastric diseases between January 2022 and October 2024, confirmed by endoscopic pathology as gastric tumors (n=82) or gastric ulcers (n=192). All underwent gastrointestinal ultrasound contrast filling. Differences in conventional ultrasound features (internal echo, calcification, morphology, classification) and contrast-enhanced ultrasound parameters [enhancement intensity (EI), time to peak (TTP), area under curve (AUC), arrival time (AT)] were compared. Spearman correlation assessed parameter-tumor relationships. ROC curves evaluated diagnostic performance.
Results: The tumor group showed higher rates of low internal echo, calcification, irregular morphology, and type II classification than the ulcer group (P< 0.05). EI, TTP, AUC, and AT were significantly elevated in tumors (P< 0.05), correlating positively with tumor occurrence (r=0.524– 0.597, P< 0.05). ROC analysis yielded an AUC of 0.947, with sensitivity 96.72% and specificity 98.91%.
Conclusion: Gastrointestinal ultrasound contrast filling effectively demonstrates both conventional and enhancement features of gastric lesions in the elderly, providing high sensitivity and specificity for differentiating gastric tumors from gastric ulcers.
Keywords: gastrointestinal ultrasound contrast filling, elderly, gastric tumor, gastric ulcer, differential diagnosis
