Conclusion
Oesophagoscopy is recommendedfor screening
synchronousoesophagealmalignancies in patients with HNSCCs, in
particular for patients who were smokers or drinkers, male patients and
hypopharyngeal cancer patients. Part of these
synchronousoesophagealmalignancies are also only detectable with
oesophagoscopy and can potentially affect the survival of patients. Due
to the low yield of bronchoscopyand can be potentially replaced by other
means of investigation, it is not recommended as a screening procedure
for patients with HNSCCs. Complication rate of oesophagoscopy and
bronchoscopy is extremely low and the procedure is well tolerated using
trans-nasal flexible endoscopy.
