title: Diagnostic and therapeutic use of the flexible nasendoscope in the management of an impacted upper oesophageal food bolus.
abstract: The flexible nasendoscope is now an integral tool in most otorhinolaryngology departments for visualizing the hypopharyngolarynx. A technique has been described using the modified Valsalva manoeuvre to improve visualization of the hypopharynx during flexible nasopharyngoscopy. The authors report an alternative technique for visualizing the upper oesophagus using the flexible nasendoscope, and highlight three cases where there was accurate visualization of an impacted oesophageal food bolus. Subsequently, these patients underwent flexible oesophagoscopy to dislodge the foreign body. The authors also describe three cases where the flexible nasendoscope was successfully used to visualize and negotiate the impacted food bolus beyond the cricopharyngeus. This is a safe and simple procedure performed without any sedation and reduces the need for prolonged hospitalization.
