Esophagus

The esophagus is the passageway that connects the throat or pharynx to the stomach. Technically, the esophagus begins at the upper esophageal sphincter and ends at the lower esophageal sphincter.

The Esophagus Doesn’t Like Being Stretched for Years Due to Untreated R-CPD

Lateral dilation from R-CPD

Lateral dilation from R-CPD (1 of 3)

In this middle-aged patient with R-CPD (inability to burp), now fully resolved (burping well for more than a year) after botox therapy. This view is pre-treatment, at mid-esophagus using an ENT scope. No air was insufflated to get this photo; the patient “has her own.” The aortic shelf is prominent, but observe the dramatic lateral dilation (arrows). S = spine; T = trachea.
Lateral dilation in the upper esophagus

Now in the upper esophagus, arrows again depict the remarkable lateral dilation.
Medial-lateral stretch

Medial-lateral stretch (3 of 3)

Opening of the esophagus is constant, due to the patient’s retained air, but as air goes downward transiently, the lumen size is reduced, almost accentuating the medial-lateral “stretch” of the esophagus. * denotes the same place in photos 2 and 3, for reference.
