It is important to know what type of tube the patient has insitu. Removal or replacement of tube is dependent on type of tube. Some tubes as shown in the images have an internal retention bolster that holds the tube in place and an external fixation device that stabilizes tube on the outside. They may need to be endoscopically removed.


Gastrostomy Tubes can be placed by three methods.
1. Endoscopic: (PEG) Percutaneous Endoscopic Gastrostomy
