What is gastrostomy tube replacement?

Gastrostomy Tube (G-tube) Replacement involves changing the feeding tube inserted through the abdominal wall into the stomach, which allows for direct delivery of nutrition, fluids, and medication when a person cannot eat or swallow by mouth.

How it Works:

1. Procedure:

• Removal of Old Tube: The current gastrostomy tube is gently removed, either because it has become dislodged, blocked, or damaged, or simply needs regular replacement.
• Placement of New Tube: A new tube is carefully inserted through the same existing stoma (opening) in the abdomen that leads directly into the stomach.
• Confirmation of Placement: The new tube is positioned to ensure it sits correctly in the stomach and functions properly.

 Imaging:

• Fluoroscopy (X-ray):
  • During the Procedure: Fluoroscopy, often with the use of contrast dye, is used to verify the new tube’s position within the stomach and check for leaks or blockages. The contrast highlights the stomach, allowing for real-time visualization to ensure that the tube enters the stomach without any complications.

• Ultrasound (in some cases):
  • Sometimes used before or during the procedure, ultrasound can help visualize the abdominal structures and identify the safest path for the tube placement or replacement.

Why It’s Done:

• Tube Dysfunction: Tubes can become blocked, damaged, or dislodged over time and need replacement for continued use.
• Infection or Leakage: If there are signs of infection or leakage around the tube, replacement may help prevent complications.
• Routine Maintenance: Some gastrostomy tubes have a limited lifespan and require regular replacement to ensure optimal functioning.
