A 10-year retrospective survey of 204 elective rigid oesophagoscopic examinations in the ENT unit of a District General Hospital is reported.

Clinical examination was usually unhelpful but barium studies were found to complement oesophagoscopy in reaching a diagnosis. There were six complications of oesophagoscopy, two following normal examinations.
