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.
In the last years the cases of swallowing deliberately "starlet" foreign bodies made especially for that purpose became more often. They lodge mostly in the esophagus. In most of the cases the endoscopic extraction is impossible and the only way for removing the body is by operation. Usually the patients are operated after the foreign body has been for a long period there and it is found that there are serious esophagitis, periesophagitis and mediastinitis. That makes it difficult to localize the foreign body and necessitates making a big esophagotomy which complicates the post-operative period. We work out a method for intraoperative localization of endoscopically unremovable foreign bodies in the esophagus. This method has a number of advantages and they improve the results from the surgical treatment of these patients.
