胃肠道间质瘤X诊断(附5例分析)

X-ray diagnosis of gastrointestinal tract stromal tumor

目的分析胃肠道间质瘤的消化道造影的X线表现,以期提高对GIST的认识。方法收集经手术及病理证实的5例GIST的消化道造影、手术及病理、临床资料。结果5例GIST中,交界性2例,良性2例,恶性1例,均行胃肠道造影,主要表现为胃或肠腔不同程度偏心性狭窄,局部黏膜展平、移位,呈外压性改变,充盈缺损或龛影,黏膜紊乱、纠集、中断、破坏消失。结论胃肠道造影检查对间质瘤的诊断具有一定的优越性,能动态的观察病变、管腔的充盈情况及邻近黏膜的充盈情况,但最终诊断有赖于病理及免疫组化。
