影像检查诊断胃隆起性病变的价值

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109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、同平滑肌肉瘤和胃息肉病变检出率类似（P＞0．05），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＜0．05或P＜0．01），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。

Value of image examination on diagnosing gastric bulgy lesion

Aim To investigate the diagnostic value of three methods of imaging examination. Methods Gastric contrast ultrasonography gastroscopy,electron endoscopy and gastrointestinal radiography (GI) were used to examine gastric bulgy lesions confirmed by operation and (or) pathology. Results The diagnostic rate of gastric carcinoma, gastric malignant lymphoma, gastric leiomyoma and gastric leiomyosarcoma and gastric polyp by gastric contrast ultrosonography was similar to that by gastroscopy ( P >0 05). The diagnostic rate with gastroscopy was higher than that with gastric contrast ultrasonography in ectopic pancreas, gastric schistosomiasis and arteriae under mucosa. For the tumor under the mucosa and the gastric bulgy lesions caused by pressure outside, the diagnostic rate by gastric contrast ultrasonography was higher than that by gastroscopy ( P <0.05 or P <0.01). Meanwhile ultrasonography was helpful to evaluate the growth pattern of carcinoma and differentiate benign lesions from malignant lesions. Conclusions As a safe, reliable and noninvasive method, gastric contrast ultrasonography is proved to be an important diagnostic means for general examination and screen of gastric bulgy lesions. Gastric contrast uctrasonagraphy was superior to electron endoscopy in imaging of gastric bulgy lesion caused by pressure outside. The combination and complemention of three methods of imaging examination can increase diagnostic rate in gastric bulgy lesion.
