24-hour pH impedance testing is a diagnostic procedure used to evaluate acid and non-acid reflux in the oesophagus. The test measures the amount and frequency of acid and non-acid reflux and determines whether the reflux is causing symptoms or damage to the oesophagus. The procedure is used to evaluate patients with gastroesophageal reflux disease (GERD) or other esophageal disorders.
During the test, a small catheter is placed through the nose and into the oesophagus. The catheter has multiple sensors that measure the pH and impedance of the esophageal contents. The patient is asked to keep a diary of their symptoms and activities during the 24-hour testing period. The data collected by the sensors and the patient diary are analysed to determine the frequency and severity of acid and non-acid reflux.
Recovery is generally quick and without complications. Patients may experience mild discomfort or irritation in the nose and throat during the placement and removal of the catheter. There may also be some temporary difficulty with swallowing or speaking during the testing period.
Mr. Ratan Hossain from Tripura underwent pH-metry Impedance Test to Detect Reflux Acidity, under the supervision of Dr. Adi Rakesh Kumar, Consultant Gastroenterologist, Therapeutic Endoscopist & Endosonologist at Yashoda Hospitals.
