Foreign bodies (FBs) in the gastrointestinal (GI) tract can show a wide range of clinical manifestations ranging from spontaneous evacuation to severe complication. Plain radiography is a straightforward and important initial imaging modality in cases of FB ingestion or insertion and is also helpful for follow-up purposes. Careful evaluations of the plain radiographs can determine the presence and nature of FBs, and help predict their precise locations and facilitate risk assessment. In this review, a wide variety of FBs in the GI tract are illustrated, and the role of plain radiography in patient management is discussed.
胃肠道（GI）内的异物（FBs）可表现出从自发排出到严重并发症等多种临床表现。在 FB 摄入或插入的情况下，普通放射摄影是一种简单而重要的初始成像方式，对于随访也有帮助。仔细评估普通放射照片可以确定 FBs 的存在和性质，并帮助预测其确切位置，有助于进行风险评估。在本综述中，展示了胃肠道内的多种 FBs，并讨论了普通放射摄影在患者管理中的作用。
