2. Gastric intubation - Wikipedia

   The tube is then marked at this level to ensure that the tube has been inserted far enough into the patient's stomach. Many commercially available stomach and duodenal tubes have several standard depth markings, for example 46 cm (18 in), 56 cm (22 in), 66 cm (26 in) and 76 cm (30 in) from distal end; infant feeding tubes often come with 1 cm ...

3. Esophageal pH monitoring - Wikipedia

   en.wikipedia.org/wiki/Esophageal_pH_Monitoring

   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.

4. Flexible Endoscopic Evaluation of Swallowing with Sensory ...

   en.wikipedia.org/wiki/Flexible_Endoscopic...

   Therefore, aspiration is common in people with chronic acid reflux disease. 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 ...

5. Esophageal motility study - Wikipedia

   en.wikipedia.org/wiki/Esophageal_motility_study

   A technician places a catheter into the nose and then guides it into the stomach. Once placed in the stomach lining, the catheter is slowly withdrawn, allowing it to detect pressure changes and to record information for later review. The patient will be asked at times to take a deep breath or to take some swallows of water.

6. Impedance–pH monitoring - Wikipedia

   en.wikipedia.org/wiki/Impedance–pH_monitoring

   Impedance–pH monitoring is a technique used in the diagnosis of gastroesophageal reflux disease (GERD), by monitoring both impedance and pH. [1] [2] Patients with ongoing symptoms while on proton-pump inhibitor (PPI) therapy are commonly diagnosed with impedance–pH monitoring while continuing their medications. The impedance–pH monitoring ...

7. Esophageal dysphagia - Wikipedia

   en.wikipedia.org/wiki/Esophageal_dysphagia

   Endoscopic image of a non-cancerous peptic stricture, or narrowing of the esophagus, near the junction with the stomach. This is a complication of chronic gastroesophageal reflux disease, and can be a cause of dysphagia. The stricture is about 3 to 5 mm in diameter. The blood that is visible is from the endoscope bumping into the stricture.

8. Heartburn - Wikipedia

   en.wikipedia.org/wiki/Heartburn

   Heartburn, also known as pyrosis, cardialgia or acid indigestion, [2] is a burning sensation in the central chest or upper central abdomen. [3] [4] [5] Heartburn is usually due to regurgitation of gastric acid (gastric reflux) into the esophagus. It is the major symptom of gastroesophageal reflux disease (GERD). [6]

9. Laryngopharyngeal reflux - Wikipedia

   en.wikipedia.org/wiki/Laryngopharyngeal_reflux

   Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. [4] [5] LPR causes respiratory symptoms such as cough and wheezing [6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. [7]
