BACKGROUND/OBJECTIVE: 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.
背景/目的：评估在禁食状态下且未使用低张药物时腹部超声检查在检测和排除胃部病变方面的效用。
纳入100例上消化道内镜检查正常的患者、94例有主要胃部异常的患者（包括59例腔内肿瘤、3例黏膜下肿块、29例溃疡、2例息肉和1例胃黏膜肥厚）以及75例有轻微胃部异常（主要为胃炎）的患者进行研究。
100例正常患者中，超声检查出现4例假阳性结果，检查特异性为96%。在主要胃部病变组中，超声对59例肿瘤中的55例、29例溃疡中的15例、3例黏膜下肿块中的3例以及巨大胃黏膜病例检查结果为真阳性。对胃息肉检测呈阴性。它仅能检测出8%的轻微胃部异常。
禁食状态下的腹部超声检查，若操作仔细，在检测和排除主要胃部病变方面足够准确。因此，尽管它不能替代胃部的内镜和钡剂检查，但在每次腹腔超声检查时建议仔细评估胃部情况。
