An endoscopic ultrasound probe placed in the esophagus can also be used to visualize lymph nodes in the chest surrounding the airways (bronchi), which is important for the staging of lung cancer. Ultrasound can also be performed with an endoscopic probe inside the bronchi themselves, a technique known as endobronchial ultrasound .
A transesophageal echocardiogram (TEE; also spelled transoesophageal echocardiogram; TOE in British English) is an alternative way to perform an echocardiogram.A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus. [1]
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Other potential tests include an esophagram (or barium swallow), which involves swallowing a contrast solution and tablet to examine the anatomy of the esophagus and mortality of the esophagus and ...
An esophageal motility study (EMS) or esophageal manometry is a test to assess motor function of the upper esophageal sphincter (UES), esophageal body and lower esophageal sphincter (LES). [ 1 ] Indications
Functional Lumen Imaging Probe (FLIP) is a test used to evaluate the function of the esophagus, by measuring the dimensions of the esophageal lumen using impedance planimetry. Typically performed with sedation during upper endoscopy, FLIP is used to evaluate for esophageal motility disorders, such as achalasia, diffuse esophageal spasm, etc. [1]
Esophagogastroduodenoscopy (EGD) or oesophagogastroduodenoscopy (OGD), also called by various other names, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum.
Transnasal esophagoscopy is an office based procedure in which the patient is anesthetized locally in the nose and sometimes the oropharynx.The scope is advanced into the ipsilateral pyriform sinus and through the esophageal inlet to the stomach, where the esophagus can be examined, with special attention paid to the gastroesophageal (GE) junction.
