Evaluation of alimentary tract foreign body: clinical and imaging review of 100 consecutive cases.

We investigated the cases of 100 consecutive patients with alimentary tract foreign bodies for clinical findings and use of imaging and compared our findings with those of other reported series. Most of our patients were children, and the alimentary tract foreign body was metal in most cases. There was no undue morbidity or mortality related to either conservative or interventional treatment. Imaging was useful in diagnosis and management of cases. Use of computed tomography and magnetic resonance imaging in evaluation of alimentary tract foreign bodies is discussed.
