| Abstract: | In the history of endoscopy, laryngologists have played an important role in knowledge of the oesophagus. For those familiar with gastroscopy, the supple fibroscope represents a diagnostic instrument which may be used for observation of the oesophagus with the exception of natural or pathological areas of stenosis. It offers considerable possibilities in the photographic documentation of lesions. It is relatively easy to perform though not completely harmless. The rigid oesophagoscope remains an effective method of investigation of the whole oesophagus, including the oesophageal opening. It remains the best method for the performance of endoscopic surgery and in particular the extraction of foreign bodies. It is not dangerous in the hands of a competent and trained operator. Rather than opposing each other, the two instruments may be seen to be complementary. |
