As the position and the course of the oesophagus are known, unilateral palpation, or, better still, bilateral palpation, employing both hands, is of very much greater service. These methods reveal the presence of swellings, infiltrations, changes in shape and sensibility, the presence of foreign bodies, the existence of dilatations or contractions of the tube, etc. Auscultation and percussion, though recommended by some prac- titioners, are not of much service.
