Abstract
Direct laryngoscopy (DL) is the standard of care for the evaluation of suspicious lesions in the larynx and hypo pharynx but requires general anaesthesia and a dedicated operation theatre. While DL offers us the ability to map the lesion adequately and take a biopsy, it requires workup for anaesthesia well as rigid oesophagoscopy for assessing the oesophagus with its associated complications. Sixty-nine patients underwent TNE under topical anaesthesia. The lesions were mapped and biopsies taken. Those patients who had an inadequate evaluation on TNE or negative biopsy underwent direct laryngoscopy. Completeness of evaluation, adequacy of biopsy, presence of synchronous oesophageal lesions and the modified Gloucester Comfort Score for patient comfort was documented. Amongst 69 cases enrolled for TNE evaluation, 97% of cases had an adequate mapping of disease extent, and 100% adequacy of biopsy material. General anaesthesia could be avoided in 92.75% of patients. TNE took a median time of 8 min. Synchronous oesophageal tumours were seen in 5.8% of patients. There were no complications and 74% patients did not experience any discomfort. TNE appears to be simple, safe, efficient office based diagnostic procedure. TNE has the potential to be the new standard of care making DL obsolete.
