摘　　要：目的：探讨植物性胃、食管、小肠石症的CT表现及诊断价值。方法回顾性分析27例经胃镜或外科手术证实的植物性胃、食管、小肠石症患者的临床资料及CT表现，其中6例行增强扫描。结果27例患者中，胃石症18例，小肠石症6例，食管石症1例，胃、小肠多发结石2例。CT漏诊7例，误诊1例，漏诊率25.93%。其主要的 CT 表现：病灶呈类圆柱形或类椭圆形混杂密度团块27例，边界清楚26例，周边见硬化缘22例，病灶内呈筛状或蜂窝状气泡影25例，增强后粪石本身无强化6例，并发小肠梗阻8例。结论胃、食管、小肠植物性粪石有典型的CT征象，认真分析总结可以提高诊断的正确率。Objective To explore the diagnostic value of CT for the vegetable stone disease in the stomach,esophagus and small intestine.Methods The clinical data and CT findings of 27 cases confirmed by endoscopy or surgery were analyzed retrospectively. Among 27 cases,6 cases performed contrast-enhanced scan.Results Among 27 cases,18 cases were the gastrolithiasis,6 cases were the intestinal stone disease,1 case was the esophagus stone disease,and 2 cases were the multiple stones of stomach and small intestine.CT missed 7 cases and misdiagnosed 1 case with the rate of missed diagnosis was 25.93%.The lesions were cylindrical or oval shape with mixed density in 27 cases,distinct boundary in 26 cases,sclerotic margin in 22 cases,ethmoid or honeycomb bub-bles in the lesion in 25 cases,no enhancement in 6 cases,and complicated small bowel obstruction in 8 cases on CT images.Conclu-sion The phytobezoars in the stomach,esophagus and small intestine have typical CT findings.Careful analyses can improve its di-agnostic accuracy.
