摘　　要：目的　探讨超声内镜对胃浸润性肿瘤的诊断价值 ,提高其内镜诊断率。方法　分析 4 4例胃浸润性肿瘤 (皮革胃 4 1例 ,胃淋巴瘤 3例 )的内镜结果 ,对其中 2 9例行超声内镜检查 ,并分析其超声影像特征。结果　皮革胃和胃淋巴瘤内镜活检阳性率为 4 3.2 % (19/44)。超声内镜显示病变胃壁弥漫性增厚 ,以 2、3和 4层为主 ,回声减弱 ,胃壁层次尚可见 ,部分病例仅见 4层结构。超声内镜诊断准确率为 10 0 %。结论　超声内镜对胃镜活检阴性的胃浸润性肿瘤具有重要的诊断价值 。Objective To evaluate the results of endoscopic ultrasonography (EUS) examination for gastric infiltrating tumours, and to improve the level of diagnosis of gastric infiltrating tumour. Methods Fourty foury gastric infiltrating tumours (41 gastric linitis plasticas and 3 gastric lymphomas) were examined by gastric endoscope. Twenty nine of the patients were referred for EUS evaluation. EUS images of gastric infiltrating tumours were analysed.Results In all patients with a final diagnosis of linitis plastica, EUS showed a diffuse thickening of layers 2, 3 and 4 with hypoecho. Five layers of gastric wall could be seen in most patients. Only 4 layers were shown in some patients. EUS provided a correct diagnosis in all patients. Conclusions EUS is a valuable method in evaluation of patients in whom gastric infiltrating tumour is suspected and biopsies are negative for malignancy. But it can not distinguish gastric linitis plastica from gastric lymphoma.
