Stage 3 Passing Through The Thoracic Esophagus





Category: INTRODUCTION OF THE ESOPHAGOSCOPE
Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery

esophagus will be seen to expand during inspiration and contract
during expiration, due to the change in thoracic pressure. The
esophagoscope usually glides easily through the thoracic esophagus if
the patient's position is correct. After the levels of the aorta and
left bronchus are passed the lumen of the esophagus seems to have a
tendency to disappear anteriorly. The lumen must be kept in axial view
and the head lowered as required for this purpose.
