目的:探讨口服超声造影技术(OCUS)诊断胃部疾病的临床应用价值。方法:?2015年3月至2016年2月采用VOLUSO E8型彩色超声诊断仪对39例患者行OCUS检查,探头为电子凸阵式探头,探头频率为3.5-5.0MHZ及7.5-10.0MHZ,观察胃的形态、蠕动频率,记录病变的位置、形态、大小等。将39例患者的OCUS诊断结果与病理诊断进行对照分析。结果:39例患者中,病理确诊胃癌21例,胃溃疡8例,胃间质瘤4例,胃部息肉6例。以病理检查为金标准,OCUS检查诊断胃癌17例,准确率为80.95%;胃镜检查诊断胃癌19例,准确率为90.48%;OCUS诊断胃癌准确率与胃镜检查相比,差异无统计学意义(P>0.05)。结论:口服超声造影技术简便无创,患者易于接受,胃部肿瘤诊断符合率较高,可作为胃部肿瘤选择性筛查的首选方法,也是胃镜、X线钡餐等检查方法之外的重要补充。
Objective: To investigate the clinical value of oral contrast-enhanced ultrasound (OCUS) in the diagnosis of gastric diseases. Methods: From March 2015 to February 2016, OCUS examination was performed on 39 patients with VOLUSO E8 color ultrasonic diagnostic apparatus. The probe was an electronic convex array probe with probe frequencies of 3.5-5.0MHZ and 7.5-10.0MHZ. Stomach morphology, peristalsis frequency, recording lesion location, morphology, size and so on. The OCUS diagnostic results of 39 patients were compared with the pathological diagnosis. Results: Of the 39 patients, 21 were gastric cancer, 8 gastric ulcer, 4 gastric gastric tumor and 6 gastric polyps. The pathological examination as the gold standard, OCUS examination of gastric cancer in 17 cases, the accuracy rate was 80.95%; gastroscopy diagnosis of gastric cancer in 19 cases, the accuracy rate was 90.48%; OCUS diagnosis of gastric cancer compared with gastroscopy accuracy was not statistically significant P> 0.05). Conclusion: Oral echocardiography is simple, noninvasive and easy to accept. The coincidence rate of gastric cancer diagnosis is high, which can be used as the first choice for selective screening of gastric tumors. It is also an important supplement to the examination methods of endoscopy and X-ray barium meal.
