Caption: Heartburn results when the lower esophageal sphincter does not close properly, allowing stomach acid to flow back into the esophagus.

As showed, there were no significant differences (all p value > 0.05) in mean age, symptom duration, LESP (lower esophageal sphincter pressure), IRP (integrated relaxation pressure), length of LES (lower esophageal sphincter), and prior history of treatment between the two groups.

During an upper EUS examination, the thyroid gland is usually visualized close to the upper esophageal sphincter. However, EUS is limited in visualizing the upper portions of the thyroid glands [4, 5].
