Is it worthwhile to fully evaluate the stomach in every ultrasound examination of the abdominal cavity?

ABSTRACT

To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. One-hundred patients with normal upper gastrointestinal endoscopy. 94 patients with a major gastric abnormality [including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa] and 75 patients with minor gastric abnormalities [mainly gastritis] were enrolled into the study. Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. Abdominal sonography in the fasting state. If carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity
