Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
Esophageal inlet patches are diagnosed by upper endoscopy (esophagogastroduodenoscopy or EGD). Detection of esophageal inlet patches may be improved by the use of specialized imaging techniques such as narrow-band imaging (optical chromoendoscopy).
