Introduction

A gastrostomy is a procedure that creates a small opening in your outer abdomen into the stomach to place a thin tube (g-tube). This tube will allow you to drain fluids out of your stomach, vent air, and give medicines. Venting can help decrease nausea or vomiting due to a blockage in your intestines. To vent, this tube can either be hooked to wall suction or attached to a soft, plastic bag at home to allow gas and/or fluid to come out. You will be taught how to attach the tube to a bag before you go home.

Using Instruction

Why do I need a venting G-tube?
Some tumors, internal scar tissue, and cancer can cause the stomach and bowels to stop working as they should. This can lead to nausea, vomiting, or bloating. A g-tube can reduce these symptoms and still allow you to enjoy drinking some liquids. You will not absorb many nutrients because the liquids you drink will drain out the g-tube and into the bag outside your body.

How often do I need to vent the tube?
If you have gas, bloating, nausea, or vomiting after eating you will be able to “vent” the g-tube by attaching the tube to a dependent drainage bag. This will allow air to escape or allow the contents of your stomach to drain to help decrease these symptoms. How often you need to do this is based on when you are having these symptoms.

What is the procedure like?

• You will have the tube placement in the Interventional Radiology (IR) suite and it often takes about 1 hour.
• If you do not already have an IV, we will start one. If safe for you, we will give IV pain medicines and medicine to make you sleepy for the procedure.
• We will use ultrasound and X-rays to help locate the correct place for the tube. We will place a nasogastric tube through your nose and into your stomach if you do not already have one. We will fill it with air which helps with tube placement. This will make you feel full but should not cause you pain. If we place the nasogastric tube during the procedure, we will remove it at the end of the procedure.
• We will place T-fasteners, which look like small white buttons on your skin. This helps move the bowel out of the way and prevents the stomach from moving during g-tube placement. You will come back to the IR clinic 7-10 days after the procedure so the nurse can look at your site and remove these T-fasteners. If they fall off before your clinic visit, that is ok because they are absorbable sutures.
• We will numb your skin with lidocaine. This will feel like a pinch and a burn.
• We will insert a small needle through the skin and into the stomach. We then insert a flexible wire through the needle and into the stomach. We will remove the needle and guide the tube into place over the wire. You may feel some pressure during the placement of the tube. We will secure the tube in place with a suture and a dressing.

How do I clean the g-tube site?
You need to clean the G-tube daily to prevent infection. Clean the skin around the tube with soap and water and then let air dry. You may shower and let the water run over the area where the tube enters your skin. The day after the procedure you no longer need to leave a dressing in place. If you prefer to leave a dressing, you may apply a 4×4 split gauze dressing. You should change the gauze every 3 days or as needed if it becomes soiled.

Check the tube site for signs of infection. These may include:

• Increased tenderness or pain.
• Increased redness or swelling.
• Drainage that is green in color or smelly.
• Sutures (stitches) at the skin site that come loose.

Giving Medicines

If you need to use the g-tube to give medicine, please review these tips. You can give medicine with a syringe through the g-tube. Crush pills in water until dissolved so that they do not clog the tube. You may want to ask your doctor about getting pills in liquid form. Never crush enteric-coated or time- release capsules. Flush the tube with 30 mL of water before and after giving medicines. This helps ensure that it enters the stomach and helps to prevent clogging the tube.

What can I eat?
Your primary care team will tell you if you can have anything by mouth or not. We suggest a liquid diet because liquids can more easily drain out of the g-tube. Be aware that if you are eating solid foods and try to vent, it could potentially clog your tube. Use a blender to blend your favorite solid foods into thin liquids. This will help you enjoy the flavors of your favorite foods without clogging the tube.

You can blend your favorite solid foods into a thin liquid by adding small amounts of fluid. You may choose to add fluids such as:

• Milk
• Cream
• Cream soups (without chunks)
• Sour cream
• Cottage cheese
• Smooth yogurt
• Ice cream (without nuts or chunks of fruit or candy)
• Half & half
• Broth
• Fruit juice
• Vegetable juice
• Nutrition supplements (Carnation Instant Breakfast®, Ensure®, Boost®, or generic versions).

Here are some liquids that you may enjoy. Remember to put solid foods in a blender with a small amount of thin liquids. Blend the mixture until the consistency is thin.

• Strained canned soups or soup that has gone through a blender
• Cooked hot cereal (thinned with milk)
• Ham with pineapple (thinned with broth, sauce, gravy, or pineapple juice)
• Pork with applesauce (thinned with broth, sauce, gravy, or apple juice)
• Beef with sweet potatoes (thinned with beef broth, sauce or gravy)
• Pureed fruits (thinned with fruit juice)
• Pureed vegetables (thinned with vegetable juice or vegetable broth)
• Fruit smoothies made with pureed fruits and ice cream or yogurt (thinned with milk)

Potential Problems

• Blocked tube
• Excessive leaking around the tube
• Redness around the tube
• Bleeding around the tube
• Stitches come loose or tube falls out
• Punctured or torn tube
• Noticing blood
• Vomiting

If you have any of these problems and feel that you need medical help, please call Interventional Radiology at 608-263-9729 option 3. Please call before going to a clinic or emergency room. Our staff will help you decide what to do next.

• Blocked Tube
  Gently flush the tube using 15 mL of warm water. You may need to flush and pull out the water many times until the tube will flush.

• Excessive Leaking Around the Tube
  Call your doctor or nurse.

• Redness Around the Tube
  Keep the skin around the tube clean and dry. Some redness is normal, but moisture can irritate the skin and lead to an infection. Clean the skin around the site more often using plain water. Keep irritated areas open to air if you can. Ask a nurse about other ways to fasten the tube in place. Call the nurse if you see signs of infection.

• Bleeding Around the Tube
  If you notice more than a few drops of blood, call your nurse. Keep the tube taped or secured tightly to your skin to prevent pulls that might cause injury.

• Stitches Come Loose or Tube Falls Out If the tube falls out partly or all the way, do not try to push it back into the opening. If you can, secure the tube with tape. You must Call the Interventional Radiology clinic within 12 hours. We will arrange an appointment for you to have the tube replaced. You do not need to go to the emergency room for this.

• Punctured or Torn Tube
  Clamp the catheter (or seal it with tape) close to your skin. Call the IR Clinic.

• Noticing Blood
  If you cough up blood or see blood clots the size of a quarter coming from the g-tube, call the IR Clinic right away. We may tell you to go to the emergency room.

• Vomiting
  You have the venting g-tube to help control nausea and vomiting. Make sure your tube is not clogged. If the tube is not clogged, you may need to adjust your nausea medicines or you may need to hook up the tube to a syringe to manually pull fluid from your stomach if it is not draining well. Also, sometimes there are certain body positions (laying down or sitting up and forward, etc) that seem to work better and allow for better drainage for patients. You can try these different suggestions to help your tube drain better.

Common Questions

Can I sleep on my stomach?

Yes. After the tube site heals, most people are quite comfortable sleeping on their stomachs.

Where do I get supplies?

You will receive supplies from the inpatient unit when you are discharged. Your hospice or home health agency will provide you with more supplies as needed.

Can I get the tube wet?

You may shower. Do not immerse the tube in water such as in a bath, swimming pool, or hot tub.

How often should I clean the g-tube site?

The g-tube site should be cleaned daily to prevent infection. Additionally, showering is allowed, and gauze dressing can be changed every 3 days or as needed.

Can I administer medications through the G-tube?

Yes, medications can be administered through the G-tube. Crush pills in water until dissolved to prevent clogging. Flush the tube with water before and after giving medicines.

Follow-Up Care

You will follow up with Interventional Radiology in 7-10 days and again in 3-6 months for a routine change of the G tube. We will schedule these visits for you.
