Stage 3 Passing Through The Thoracic Esophagus


Categories: INTRODUCTION OF THE ESOPHAGOSCOPE
Sources: A Manual Of Peroral Endoscopy And Laryngeal Surgery

The thoracic

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.
