Catheter:Â Â Â French ballooned gastrostomy tube
Complications:Â None immediate.
Procedure:
The risks, benefits, and alternatives to the procedure and sedation were explained to the patient. Written informed consent was obtained. A time out/call to order was performed prior to procedure initiation.
The anterior abdominal wall and existing gastrostomy tube were prepped and draped in sterile fashion. A scout radiograph was obtained.
Contrast was injected through the existing gastrostomy tube.
A short Amplatz wire was placed through the existing gastrostomy tube and the tube removed over the wire.
A new gastrostomy tube was advanced over the wire. The balloon was inflated with 15 mL saline. Contrast injection confirmed placement.
The site was dressed.
The procedure was well-tolerated, and the patient was discharged from the angio suite in satisfactory condition.
Findings:
The existing gastrostomy is adequately positioned.
The new gastrostomy tube is adequately positioned within the gastric lumen.

Frequently Asked Questions
What is a gastrostomy tube replacement?
A gastrostomy tube replacement is a medical procedure where an existing gastrostomy tube, used for feeding directly into the stomach, is replaced with a new one. This is often done when the tube is worn or leaking. The procedure involves inserting a new tube over a guidewire after removing the old one, confirming its placement with contrast imaging, and ensuring it's secure.
Why might a gastrostomy tube need to be replaced?
A gastrostomy tube might need replacement due to wear and tear, leakage, or blockage. Over time, the materials can degrade, affecting the tube's functionality. Regular assessments are necessary to determine when a tube replacement is required to maintain effective feeding and prevent complications.
The procedure begins with informed consent and a sterile preparation of the site. The current tube is evaluated using contrast fluid. A guidewire is inserted through the existing tube, which is then removed. The new tube is advanced over the guidewire into the stomach, and its placement is confirmed with imaging before securing it in place.
What are the risks of gastrostomy tube replacement?
While generally safe, risks of gastrostomy tube replacement can include infection, bleeding, or injury to the stomach or abdominal wall. However, these complications are rare. The procedure is typically well-tolerated when performed under sterile conditions by experienced medical professionals.
How is the placement of a new gastrostomy tube confirmed?
The placement of a new gastrostomy tube is confirmed using contrast imaging. After the tube is positioned, a contrast agent is injected through it, and X-rays are taken to ensure the tube is correctly within the stomach, preventing any feeding complications.
What preparation is needed before a gastrostomy tube replacement?
Before the procedure, patients are informed about the risks, benefits, and alternatives, and written consent is obtained. The abdominal area is sterilized, and a scout radiograph is taken to evaluate the existing tube. This preparation helps minimize infection risks and ensures the new tube is placed accurately.
How long does a gastrostomy tube replacement take?
The gastrostomy tube replacement is typically a brief procedure, often completed in under an hour. The precise duration can depend on the patient's specific circumstances and the need for any additional interventions, but fluoroscopy time is usually kept to a minimum to reduce radiation exposure.
What should be expected after a gastrostomy tube replacement?
After the replacement, the site is dressed, and the patient is monitored for any immediate complications, such as discomfort or signs of infection. Most patients tolerate the procedure well and can be discharged shortly afterward, resuming regular activities with some dietary and care instructions for the new tube.
