A retrospective study of four patients at Singapore Tan Tock Seng Hospital was done to evaluate the presentation, investigation, and diagnosis of migrated forcing bodies.
Migration is said to have occurred in the presence of positive neck radiography and negative rigid esophagoscopy. Computed tomography is the investigation of choice to confirm migration and invaluable in localising the foreign body for exploration.
All the migrated foreign bodies were linear, sharp fish bones and had been removed successfully.
Ingested foreign bodies which migrate extra-luminally are rare occurrences, and they may result in life threatening complications and should be treated.
对新加坡陈笃生医院的4例患者进行回顾性研究，以评估移位异物的表现、检查及诊断情况。
颈部X线检查阳性而硬质食管镜检查阴性时即认为发生了异物移位。计算机断层扫描是确认异物移位并对定位异物以进行探查极有价值的检查方法。
所有移位异物均为细长、尖锐的鱼骨，均已成功取出。
管腔外移位的误吞异物很少见，可能导致危及生命的并发症，应予以治疗。
