摘　　要：目的：探讨空腹经腹壁常规超声诊断胃病变的价值。材料与方法：患者禁食水 １０小时以上，常规超声探查胃声像图特征及周围淋巴结情况，超声与胃镜和手术结果对照分析。结果：超声对正常胃的显示率为 ９７％，正常组、胃溃疡组、胃癌组的胃壁厚度分别为４．１± ０．２４ｍｍ、７．８± ２．６ｍｍ、１６．９± ５．５ｍｍ，各组间均存在显著差异，以胃壁厚度 １０ｍｍ为截断点，超声诊断胃癌的敏感性为 ９３％，特异性为９７％，准确度为 ９６％。对伴随淋巴结转移的诊断符合率为８９％。结论：超声诊断胃病变是一项简便迅速有效的方法，可作为胃镜和Ｘ线钡透的有效补充，对临床决策具有重要价值。Purpose: To investigate the diagnostic value of ultrasonography in gastric diseases at fasting conditon. Materials and Method: Patients who fasted for over 10 hours were examined by conventional ultrasound to study the ultrasonogram feature and to observe surrounding lymph nodes. The results of ultrasound were compared with that of endoscopy or surgical operation. Results: In fasting condition, the detection rate of normal stomach by ultrasound was 97%. The thickness of gastric wall were 4. 1±0. 24mm .7. 8± 2. 6mm and 16. 9± 5. 5mm respectively in normal, ulcer and carcinoma group. There were significant differences (P<0. 001 ) among them. When the criteria was set at 10mm, the sensitivity, specificity and accuracy of ultrasound in diagnosing carcinoma of stomach were 93%, 97 % and 96 % respectively. The accuracy was 89% for lymph node metastasis by ultrasonography. Conclusion: conventional ultrasonography is a simple, rapid and useful method to detect gastric diseases. It is an effective complement to endoscopy and X - ray contrast study.
