Abstract

Background: Foreign body ingestion is a common clinical problem in Hong Kong. Some recent reports have proposed the use of flexible nasoendoscopy for foreign body retrieval. The present study is a prospective randomized trial on the use of the flexible gastroscope and bronchoscope in the management of foreign body ingestion. Methods: Two hundred sixteen patients older than 11 years were prospectively randomized to flexible endoscopic examination using either the gastroscope (108 patients) or the bronchoscope (108 patients). The duration of the procedure was noted. Patients were asked to assess their overall tolerance to the procedure on a scale of 1 (well tolerated) to 10 (unacceptable). Results: A foreign body was retrieved in 68 patients (31.5%). There was no difference between the two groups in the foreign body retrieval rate, type of foreign body retrieved, duration of procedure, and tolerance level. In the group managed with the bronchoscope, however, three patients required the additional use of the gastroscope for foreign body retrieval at (for one patient) or below (for two patients) the cricopharyngeus. The patient's tolerance level was related only to the duration of procedure (rho = 0.386; p < 0.001). Conclusion: The use of the flexible gastroscope is recommended because of its efficacy, safety, and tolerability.
