超声内镜联合CT对胃间质瘤的临床诊断价值

目的:评价超声内镜联合C T对胃间质瘤(gastric stromal tumors,GST)的临床诊断价值.方法:胃镜检查发现胃隆起性病变的病例同时行超声内镜及CT检查,将超声内镜和CT检查的诊断结果与手术后组织病理检查结果进行对比.结果:27例胃黏膜下隆起性病变中,直径<3cm为11例,超声内镜诊断率为85.2%,CT诊断率为62.7%;直径为3-5cm为9例,超声内镜诊断率为68.4%,CT诊断率为76.2%;直径>5cm为7例,超声内镜诊断率为59.2%,CT诊断率为83.7%,同时行超声内镜及CT检查诊断率为95.3%.结论:超声内镜联合CT检查是胃间质瘤的最佳诊断方法.

Diagnostic value of endoscopic ultrasonography combined with CT in gastric stromal tumors

AIM:To evaluate the diagnostic value of endoscopic ultrasonography and CT in gastric stromal tumors.METHODS:Twenty-seven patients who were found to have gastric protrusion lesions by gastroscopy underwent endoscopic ultrasonography and CT examinations.The results of endoscopic ultrasonography and CT examinations were then compared with postoperative pathological results.RESULTS:In 11 patients who had lesions less than 3 cm in diameter,the diagnostic yield of endoscopic ultrasonography was 85.2% and that of CT was 62.7%.In 9 patients who had lesions 3-5 cm,the diagnostic yield of endoscopic ultrasonography was 68.4% and that of CT was 76.2%.In 7 patients who had lesions greater than 5 cm,the diagnostic yield of endoscopic ultrasonography was 59.2% and that of CT was 83.7%.The diagnostic yield of endoscopic ultrasonography combined CT was 95.3%.CONCLUSION:Endoscopic ultrasonography combined with CT is the best method for diagnosis of gastric stromal tumors.
