Study Notes

Esophageal Structure and Function

The normal thickness of the wall of a distended esophagus is 3-4 mm.

Evaluating Esophageal Motility

Esophageal motility is evaluated through esophagram or fluoroscopy, which involves swallowing a barium sulfate solution or a contrast material while being recorded by X-ray or video.

Abnormal Swallowing Symptoms

Symptoms of abnormal oral or pharyngeal swallowing include difficulty swallowing, pain while swallowing, coughing, or choking on food or liquids.

Esophageal Anatomy and Function

Normally, air or contrast is not visible within the lumen of the esophagus.

Esophageal Emptying

In the upright position, esophageal emptying is affected by gravity, which aids in the rapid emptying of the esophagus.
