摘　　要：【目的】探讨胃窗超声造影在诊断进展期胃癌的应用价值。【方法】回顾性分析46例经胃镜活检或手术病理证实为进展期胃癌患者的胃窗超声造影声像图,进行Borrmann分型,并与胃镜检查行自身对照。【结果】胃窗超声造影诊断进展期胃癌42例,误诊为单纯性胃溃疡2例,漏诊2例,诊断符合率为91.30%,其中BorrmannⅠ型、Ⅱ型、Ⅲ型、Ⅳ型分别为6、19、9、8例。胃镜检查诊断进展期胃癌44例,漏诊2例,诊断符合率为95.65%。【结论】胃窗超声造影对进展期胃癌的诊断符合率高,可作为胃镜的辅助检查及进展期胃癌的初筛手段。[Objective] To investigate the clinical value of oral contrast enhanced ultrasonography in diagnosing advanced gastric cancer.[Method] We retrospectively reviewed the ultrasonography of 46 patients with advanced gastric cancer,using the Borrmann classification.All cases underwent preoperative oral contrast enhanced ultrasonography followed by gastroscopy and were provedby pathology after biopsy or surgery.The accuracy of oral contrast enhanced ultrasonography in diagnosing advanced gastric cancer was analyzed and compared to that of gastroscopy.[Result] We identified a total of 42/46 （91.3％） patients with advanced gastric cancer on oral contrast agent ultrasonography.The neoplasms of Borrmann Type Ⅰ,Ⅱ,Ⅲ,Ⅳ were detected in 6、19、9、8 cases,respectively.There were two false negative findings,while the other two cases were misdiagnosed as gastric ulcers.Gastroscopy identified advanced gastric carcinomas in 44/46 （95.65％） patients,remaining the other two false negative findings.[Conclusion] Oral contrast enhanced ultrasonography is an accurate detecting method for advanced gastric carcinoma and compares favorably with gastroscopy.It is proposed to be a complementary method for gastroscopy and an important modality among screening patients with high risk of gastric cancer in junior hospitals.
