The head should be 15cm higher than the tabletop, first insert the esophagoscope along the right side of the mouth into the pear-shaped fossa on the right side of the hypopharynx, and then gradually move the distal end of the esophagoscope to the midline, and then advance the lens orifice behind the arytenoid cartilage Under the advancement of the esophageal fistula, the pharynx muscles in the posterior wall of the esophageal swell are seen as a threshold. The esophageal sphincter should wait for the esophageal orifice to open automatically, or the patient should be asked to swallow.
