• During the procedure, a local anesthetic (pain-relieving medication) will be applied. This produces numbness in your nose to make it comfortable for the passage of a flexible tube through your nose, down your esophagus, and into your stomach. 
  • You may have to swallow a small amount of water to help assesses how well the sphincter and muscles are working. 
  • The strength of the contractions of the muscle is determined along several tube sections.
  • Sometimes after the manometry, your doctor may ask you to undergo pH testing to determine the severity of your disease.

pH monitoring

  • For pH monitoring a thin, narrow tube with a sensor on the end that detects acid is passed softly through your nose into the food pipe and is held about 2 inches above the lower esophageal sphincter.
  • The tube that comes out of your nose is attached to a recording device that is portable and can be worn on your belt or over your shoulder.
  • You are expected to continue all the routine activities and press the appropriate buttons on your recorder during activities, as instructed by your care team.
