Patient Information
Radiologically Inserted Gastrostomy (RIG)
Information for patients
This guide provides information about radiologically inserted gastrostomy (RIG) feeding tube insertion. It explains why a RIG may be recommended, what the procedure involves, and what to expect afterwards. It is intended to support – not replace – discussions with your medical, nursing, and nutrition teams.
1) What is a radiologically inserted gastrostomy?
A radiologically inserted gastrostomy (RIG) is a feeding tube placed directly into the stomach through the skin using X-ray guidance. The tube allows nutrition, fluids, and medications to be given safely when swallowing is difficult or unsafe.
The procedure is performed by an interventional radiologist using imaging to accurately locate the stomach and place the tube.
2) Why might a RIG be recommended?
A RIG may be recommended if:
- Treatment (such as cancer therapy or neurological illness) affects the ability to eat and drink
- Swallowing is unsafe due to risk of food or fluid entering the lungs
- Oral intake is not sufficient to meet nutritional needs
- Ongoing supplementary nutrition has been recommended by the nutrition or dietetics team
Your referring doctor or dietitian will discuss the reasons specific to your situation.
3) What happens during the procedure?
- The procedure is performed in a hospital angiography suite
- A temporary tube is passed through the nose into the stomach to help inflate the stomach during the procedure
- You will receive local anaesthetic at the insertion site and often light sedation. Anaesthetic support is provided in the private hospital setting and anaesthetic options can be individualised in discussion with the anaesthetist.
- Using X-ray guidance, the stomach is secured using anchor sutures and a small opening is made in the skin
- The feeding tube is placed into the stomach and held in position with a small internal balloon
The procedure itself usually takes around 30 minutes, although you should expect to be in the department longer for preparation and recovery.
4) After the procedure
- You will be monitored closely and usually return home the same day
- You and/or your carers will receive education on how to use and care for the tube
- If there are no complications, feeding through the tube usually begins a few hours after insertion
- Ongoing feeding plans are managed by your nutrition and dietetics team
5) How long will the tube stay in?
This depends on your individual medical needs. The tube may be temporary or longer-term and will remain in place until it is no longer required. Removal is arranged by your medical team when appropriate.
6) Frequently Asked Questions
Will the procedure be painful?
Local anaesthetic is used to numb the area. You may feel pressure or discomfort during the procedure, but significant pain is uncommon and pain relief is provided. Anaesthetic support is provided in the private hospital setting and anaesthetic options can be individualised in discussion with the anaesthetist.
Will there be bruising or soreness?
Some tenderness or bruising around the tube site is common for a few days.
Who looks after the tube afterwards?
Tube care, feeding, and dressings are managed by your ward nurses, community nurses, or dietetics team, depending on where you are receiving care.
What should I watch out for at home?
Seek medical advice if you develop increasing pain, redness, leakage around the tube, fever, or if the tube becomes dislodged.
