目的:探讨胃溃疡与胃癌的超声诊断价值。方法:患者常规检查后饮用400ml水加胃显液。观察胃病变的部位,胃壁的厚度和蠕动情况。结果:1.58例胃溃疡的声像图特征,病灶区胃壁增厚在0.5～0.8cm,回声减低,凹口直径>凹底.可有光点附着或显像液充填;2.26例胃癌多发于胃小弯近胃窦部。(1)恶性溃疡胃壁局限性增厚隆起,多在1.0～1.2cm,回声减低,表面不平;(2)肥厚型,病变区胃壁结构消失,肿块凸入胃腔,壁厚>1.5cm,呈“火山口征”,胃壁僵硬,蠕动波消失。结论:多普勒超声对胃溃疡、胃癌诊断率高,显像清晰,不仅能清晰显示胃腔内的病变,还能显示病变内部结构及胃腔外周邻器官情况,值得推广应用。
Objective: To investigate the diagnostic value of ultrasound in gastric ulcer and gastric cancer. Methods: After routine examination of patients drinking 400ml of water plus gastric fluid. Observe the site of gastric lesions, stomach wall thickness and motility. Results: The ultrasonographic features of 1.58 cases of gastric ulcer showed that the thickening of the gastric wall in the lesion ranged from 0.5 to 0.8 cm, the echogenicity was reduced, the diameter of the notch was larger than the concave end, and there was light attachment or imaging fluid filling. Small bend near the antrum. (1) the limitations of gastric ulcer thickening uplift, mostly in the 1.0 ~ 1.2cm, echo reduced, uneven surface; (2) hypertrophic lesions in the gastric wall disappeared, the mass protruding into the gastric cavity, wall thickness> 1.5cm, was “Crater sign”, the stomach wall stiffness, peristaltic wave disappeared. Conclusion: Doppler ultrasound has high diagnostic rate and clear imaging of gastric ulcer and gastric cancer. It can not only clearly show the lesions in the gastric cavity, but also reveal the internal structure of the lesion and the adjacent organ in the gastric cavity, which is worth popularizing and applying.
