Capsule PH Monitoring for Reflux

The oesophageal pH test measures and records the pH in your oesophagus to determine if you have gastroesophageal reflux disease (GERD). The test can also be done to determine the effectiveness of medicines or surgical treatment for GERD. The test works by temporarily attaching a small capsule (size of a gel cap) to the wall of the oesophagus to measure pH levels while device transmits readings to receiver worn on belt by the patient. 

WIRELESS CAPSULE PH METRY

Indications: 

  • Heartburn and regurgitation that do not respond to treatment with medications. 

  • Atypical symptoms of GERD such as chest pain, coughing, wheezing, hoarseness, sore throat. 

  • Occasionally, this test can be used to monitor the effectiveness of medications used to treat GERD. 

  • The test is often used as part of a pre-operative evaluation before anti-reflux surgery 

Side-effects: 

  • The capsule device may cause a vague sensation in the chest or discomfort when swallowing. This may be due to food tugging on the capsule as the food passes, although discomfort occasionally can be felt when swallowing only saliva 

Contra indications 

  • Patients cannot have an MRI (Magnetic Resonance Imaging) during the test and for 30 days afterwards. 

  • Patients with pacemakers, implantable defibrillators or neurostimulators. 

  • Patients with a history of bleeding diatheses, strictures, severe esophagitis, varices, obstruction, and prior oesophageal resection.
