A Gastrostomy Tube (often referred to as a G-tube, or a RIG when placed by a radiologist) provides a direct pathway for nutrition into your stomach through the abdominal wall.
Common Indications for Gastrostomy Tube
Your doctor may request this procedure if you:
- Have difficulty safely swallowing food or liquids (dysphagia) due to a stroke or other neurological conditions.
- Need long-term nutritional support due to severe weight loss.
- Are undergoing treatments for head, neck, or throat cancers that make eating impossible.
What happens during the procedure?
You will lie flat on your back on an imaging table. The radiologist will use an ultrasound to carefully locate your liver and spleen to ensure they are safely out of the way. Then, using continuous X-ray video for precision, they will numb the skin on your belly. A small needle is guided directly into your stomach. Sometimes, tiny anchors called T-fasteners are used to temporarily hold your stomach against your abdominal wall. Finally, a soft, flexible feeding tube is slipped through the opening and secured in place.
Do I need to prepare?
Yes. You must fast for 8 hours before the procedure to ensure your stomach is completely empty. You must also pause blood-thinning medications, as directed by your doctor.
How long does it take?
The placement is relatively quick, generally taking between 30 and 45 minutes.
Will it be painful?
You will receive local numbing medicine, which may cause a brief pinch and a burning sensation. You may also receive IV sedation to help you relax. You might feel a dull pushing or pressure as the tube is inserted, but you should not feel sharp pain.
Conclusion
A radiologically inserted gastrostomy is a safe and reliable method to ensure your body receives the calories and medicine it needs when eating by mouth is not an option.
