Objective:
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.
Method:
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.
Result:
All the migrated foreign bodies were linear, sharp fish bones and had been removed successfully.
Conclusion:
Ingested foreign bodies which migrate extra-luminally are rare occurrences, and they may result in life threatening complications and should be treated.
