P.E.G. Tube Replacement

Percutaneous Endoscopic Gastrostomy Tubes (P.E.G.) - Tube Replacement
Your Gastrostomy tube needs to be replaced
Your doctor has asked us to replace your percutaneous endoscopic gastrostomy tube (P.E.G. tube)

This is a simple procedure involving the removal of the existing feeding tube and replacing it with a new one. It may or may not involve a gastroscopy, depending on the type of tube you currently have in place. A gastroscopy is an examination which allows the doctor to look directly at the inside of your gullet (oesophagus), stomach, and first part of the small bowel (duodenum). This is done by passing a narrow flexible tube through the mouth into the stomach.

How to Prepare
Your stomach needs to be empty so the doctor can see clearly.

Morning Appointments Afternoon Appointments
Have nothing to eat or drink and/or nothing through your feeding tube after 10 pm the night before the procedure Have nothing to eat or drink and/or nothing through your feeding tube after a light breakfast at 7am on the day of your procedure

Usual medications may be taken up to 1 hour before the procedure, with a small amount of water. Avoid taking antacids e.g. Mylanta.

What to Expect
A nurse or doctor may put an injection port into a vein in your arm through which pain relieving medication can be given if you need it. If you have this medication you will need to rest in the department afterwards. For people who have an active lifestyle, having the medication will affect your activities. Please defer from the following for 24 hours:
  • driving
  • operate machinery
  • undertake strenuous activity
  • drink alcohol 
  • going to work

Following these injections you must not drive, take public transport unaccompanied or operate machinery until the next day. If transport is problematic for you, please discuss this with the gastroenterology nurse during your pre-procedure telephone conversation. 

You may resume your usual routine after 24 hours.

If you do not require medication for your procedure, you will be able to leave straight away and resume your usual activities immediately.

The way your existing tube is removed depends on the type it is. Mostly, it can be gently pulled out by external traction. A doctor or nurse who is experienced in this technique will do this. 

After the examination
Once the P.E.G. is replaced your nurse will monitor you until you are ready to go home.
Safety and Risks
P.E.G. tube replacement is relatively uncomplicated, but occasionally problems arise. Bleeding or infection can occur around the tube placement site, and infrequently damage to other abdominal organs may occur. These complications are rare, and the majority of people will have the procedure performed in a straightforward manner. If you or your representative wish to know more details of rare complications, please indicate to your nurse that you wish to discuss all complications fully with the doctor.

Gastroscopy is a safe procedure and complications are very rare. Major complications occur once in every 7000 procedures. If you have a gastroscopy you may experience a sore throat for a day or two. Please note that if you have a crown or bridging work on your teeth, these may be at risk during the procedure. This can be avoided simply by not biting the mouth guard or grinding your teeth during the gastroscopy. If you wish to discuss risks further with the doctor, please indicate this to your nurse.
