The Dedo-Pilling laryngoscope was used instead of the rigid
esophagoscope because the larger working channel allowed a better angle of approach for the endoscopic forceps.
The prosthesis was retrieved without difficulty by grasping it with biopsy forceps (Olympus Endobronchial Alligator Jaw Forceps, FB 15C-1) passed through the
esophagoscope side channel, then withdrawing the entire bronchoscope out of the trachea-stoma.
The other modalities of treatment involve removal with a laryngoscope in case of foreign bodies impacted in the pharynx, hypopharyngoscope for hypopharyngeal foreign bodies, and less easily foreign bodies are removed using a flexible
esophagoscope. [7] In the present case, rigid esophagoscopy was performed under general anesthesia and foreign body removal was performed with forceps.
(13, 14) While removal under direct vision is the method of choice, conventional pediatric
esophagoscopes of small size are difficult to work with, because of limited "straw" vision.
esophagoscope, which has a single-use, disposable sheath.
A transnasal
esophagoscope is passed through the most patent naris into the hypopharynx and pharyngoesophageal segment.
(1) The flexible
esophagoscope has only limited applicability for removal of upper esophageal foreign bodies, but it is superior to rigid esophagoscopy for circumferential visualization of the esophageal mucosa.
Approximately 3 to 4 mm is required for a nasopharyngoscope and slightly more than 5 mm for a transnasal
esophagoscope.
Another method involves the use of a transnasal
esophagoscope with a 1.8-mm biopsy forceps placed through the side channel (figure 4, B).
To examine the distal trachea or lower airway, it is necessary to use a longer flexible endoscope, such as a bronchoscope or a transnasal
esophagoscope. Again, a side channel is required for delivery of topical anesthetic, biopsy, or suctioning.
A less expensive alternative is to use a fiberoptic transnasal
esophagoscope attached to a standard endoscopic camera.
Following administration of topical anesthesia, a transnasal
esophagoscope (TNE) was used to perform tracheobronchoscopy.
