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。
Objective To investigate the value of imaging diagnosis of gastrointestinal stromal tumors. Methods Retrospective analysis of 11 cases of gastrointestinal stromal tumors confirmed by surgery and pathology. Gastrointestinal barium double biopsy was performed in 10 cases, CT scan was performed in 4 cases, superior mesenteric artery angiography in 2 cases and electronic fiber endoscopy in 7 cases. Results The tumor was located in the stomach in 7 cases, 2 cases of small intestine, the upper esophagus and the lower esophagus to cardia in 1 case. Lesion detection rate: Gastrointestinal double contrast barium 100%, CT 75%, 100% of the superior mesenteric artery angiography, endoscopy 100%. Conclusions Barium double contrast and endoscopy are the important methods for screening of gastrointestinal stromal tumors. CT and arteriography have some value in the localization of gastrointestinal stromal tumors to extraluminal growth and the diagnosis of benign and malignant diseases.
