影像学检查对胃肠道间质瘤诊断价值的临床分析

目的探讨胃肠道间质瘤的影像学诊断价值。方法对11例经手术病理确诊的胃肠道间质瘤进行回顾性分析。10例行胃肠道气钡双重造影,4例行CT检查,2例行肠系膜上动脉造影,7例行电子纤维内镜检查。结果肿瘤位于胃部7例,小肠2例,食管上段及食管下段至贲门各1例。病灶检出率:胃肠道气钡双重造影100%,CT检查75%,肠系膜上动脉造影100%,内窥镜检查100%。结论气钡双重造影和内窥镜检查是胃肠道间质瘤筛选的重要方法,CT检查和动脉血管造影对胃肠道间质瘤向腔外生长型定位及判断良恶性有一定价值。

The Evaluation of Imaging Examination in the Diagnosis of Gastrointestinal Stromal Tumor

Objective To explore the imaging diagnostic value of gastrointestinal stromal tumor(GIST).Methods The retrospective study on GIST proved by operation and pathology in 11 cases was done.There were pneumobarium double contrast examination in 10 cases,CT scanning in 4 cases,superior mesenteric ateriography in 2 cases and fiberoptic endoscopy in 7 cases.Results The locations of tumors at gastric were 7 cases,intestinal 2,lipper and row oseophagus to gastric cardiac in 1,respectively.The detective rate of GIST was 100%,75%,100% and 100% respectively by pneumobarium double contrast examination,CT,arteriography and fiberoptic endoscopy.Conclusion Pneumobarium double contrast examination and fiberoptic endoscopy are important methods for diagnosis of GIST.CT and arteriography can better show the location of tumors and differential diagnosis of benign and malignant of tumor.
