目的 探讨三种影像方法对胃隆起性病变的诊断价值。方法 对 10 9例经超声、胃镜和X线胃肠造影 (GI)进行检查后经手术或和病理证实的患者进行对比研究。结果 胃声学造影与电子胃镜相比 ,对隆起性胃癌、胃恶性淋巴瘤、胃平滑肌瘤、胃平滑肌肉瘤和胃息肉病变检出率类似 (P >0 0 5 ) ,而对异位胰腺、胃血吸虫病和胃恒径动脉出血电子胃镜的检出率明显高于胃声学造影检查。相反 ,胃外压迫所致胃内隆起性病变胃声学造影检出率较电子胃镜为高 (P <0 0 5或P <0 0 1) ,且有助于隆起性病变生长方式和良、恶性鉴别。结论 胃声学造影作为一种安全、可靠、无创伤、可追踪复查的检查手段 ,为普查和筛选胃隆起性病变类型提供了重要的诊断诊据。三种影像检查方法联用和互补可提高本病的诊断率
Objective To investigate the diagnostic value of three imaging methods for gastric uplift lesions. Methods A comparative study of 109 patients who were surgically or pathologically confirmed by ultrasonography, endoscopy and radiographic gastrointestinal imaging (GI) was performed. Results Compared with electronic gastroscope, gastric acousto-imaging showed a similar detection rate to the patients with elevated gastric cancer, gastric malignant lymphoma, gastric leiomyoma, gastric leiomyosarcoma and gastric polyp lesions (P> 0.05), while the ectopic pancreas, Gastric schistosomiasis and gastric arterial hemorrhage electron gastroscopy detection rate was significantly higher than the gastroscopy. On the contrary, the rate of gastric acoustic imaging in gastric uplift lesions caused by extra-gastric pressure was higher than that in electronic gastroscope (P <0.05 or P <0.01), and it was helpful for differentiating the growth pattern of benign and malignant lesions . Conclusion Gastric acousto-angiography is a safe, reliable, noninvasive and traceable examination method, which provides important diagnostic evidence for screening and screening of gastric uplift lesions. The combination of three imaging methods and complement each other can improve the diagnosis of the disease
