This page provides information regarding the Manometry service offered by LapSurgery Australia. You may have been advised by your doctor to undergo a Manometry study to assess your oesophagus. This can be done using our high resolution ManoScan machine which assesses the functioning of your oesophagus. You may also need to wear a monitor for 24 hours to assess acid levels in your oesophagus.

Manometry

Manometry is conducted by passing a small plastic tube (catheter) into the oesophagus via the nose. A local anaesthetic spray makes this more comfortable. During the study you will be asked to hold and then swallow small amounts (5ml) of water or saline. The Manoscan machine then measures the function of your oesophagus. The Manometry studies should take approximately 30 minutes to perform and you are able to drive yourself home following the procedure.

24-Hour Acid Study (pH Study)

For the pH studies, the first catheter is removed and replaced with a fine catheter that can stay in place for the 24 hours. This is then connected to a recording device worn under your clothing and secured with a belt. The catheter is secured to the nose with tape. You can go about your daily activities but may prefer to stay at home as the catheter is easily visible.

If a 24-hour pH study is performed you will need to return the next day for removal of the catheter and returning of the recording device. A deposit of $300 is payable on the day for the pH recording device and will be refunded on return. During the 24-hour study it is important that you eat and drink normally. You should also eat a “challenge” meal which is high in fat and more likely to show a strong acid response. This may be pizza, hamburger and chips or another food of your choice.

You will be instructed how to record certain events during the 24-hour study such as meals, medications and sleeping. These will be recorded both on the device (by pressing certain buttons) and in a written diary.

Prior to your procedure, you will need to do the following:

1. Cease any of the following medications for 10 days including:

  • Omeprazole (Losec)
  • Lansoprazole (Zoton)
  • Esomeprazole (Nexium)
  • Pantoprazole (Somac)
  • Rabeprazole (Pariet)
  • Ranatidine (Zantac)
  • Cimetidine (Tagamet)
  • Famotidine (Pepcid)
  • Nizatidine (Axid)
  • Mylanta/Gaviscon


2. Cease any sedatives such as Valium for 24 hours

3. Fast for a minimum of 6 hours.

4. Inform staff of any allergies you may have to tapes or medications.
