Sensory testing can quantify and assess the swelling for better treatment. The strength of the air pulse given during sensory testing in acid-injured vocal cords due to acid reflux disease will necessarily be much greater in order to elicit an airway reflex than tissues that are not swollen.

Capsule endoscopy can still not yet replace standard endoscopy for various diseases, as is the case for those with cirrhosis. [ 14 ] As of 2014, research was targeting additional sensing mechanisms and localization and motion control systems to enable new applications for the technology, for example, drug delivery.
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]
In gastroenterology, esophageal pH monitoring is the current gold standard for diagnosis of gastroesophageal reflux disease (GERD). It provides direct physiologic measurement of acid in the esophagus and is the most objective method to document reflux disease, assess the severity of the disease and monitor the response of the disease to medical or surgical treatment.

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.
Not all patients with Schatzki rings have symptoms; barium swallow tests of the esophagus sometimes show Schatzki rings in patients with no swallowing difficulties. [ citation needed ] When Schatzki rings cause symptoms, they usually result in episodic difficulties with swallowing (dysphagia) solid foods, or a sensation that the food "sticks ...
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.
