Has someone in your family, perhaps an elderly grandmother, grandfather, or someone suffering from an illness, had difficulty swallowing food and drink, and the doctor said, "You need to put in a feeding tube"? It's normal to feel a little scared and nervous when you hear that. When you hear words like "PEG tube," you probably wonder what this is doing. Don't worry. Today, let's talk about what a PEG tube is, who needs it, and how this procedure works.
Simply put, what is this PEG tube?
A PEG tube is a special tube that is inserted through a small incision in the skin to provide nutrition directly into the stomach for someone who has difficulty eating by mouth. While the name may sound a bit complicated, let's break it down.
- Percutaneous: This means "through the skin."
- Endoscopic: This means using a flexible tube (endoscope) with a camera attached.
- Gastrostomy: This means creating a small opening (`stomy`) in the stomach (`Gastro`).
So when these three words are combined, the simple meaning is "to make an opening in the stomach through the skin, with the help of a camera, and insert a tube." Some people also call this tube a G-tube. In medicine, the method of providing liquid nutrition in this way is called `(Enteral Nutrition)`.
Who needs a PEG tube?
The main reason is difficulty swallowing . In medicine, we call this ``dysphagia``. Although swallowing food is a very normal thing for us, it is a complex process that involves many brain, nerves, and muscles. Any time this process is interrupted, the need for a feeding tube may arise. Imagine, if you cannot swallow properly, food and drink can go into the lungs. This can lead to severe pneumonia (`Aspiration Pneumonia`).
Let's look at the table below to see what are the main reasons for placing a PEG tube.
| Medical condition | Why is a PEG tube needed? |
|---|---|
| Stroke | A stroke can damage the parts of the brain that control the swallowing process, causing the muscles needed to swallow to stop working properly. |
| Head and Neck Cancer | Swallowing may be difficult due to the cancer itself. Or, after treatments such as radiation, the throat may be damaged and the pain may make it impossible to swallow food. |
| Brain Injury | When the brain is damaged by something like a car accident, many of the body's functions, including the process of swallowing, can be impaired. |
| Anorexia caused by serious illness | In severe diseases such as cancer, the loss of appetite and weakness of the body make it impossible to absorb the necessary nutrition through the mouth. |
| Other situations | Some patients (e.g. Cystic Fibrosis) do not absorb nutrients properly. People with kidney failure who are on dialysis, and patients in a coma, also need this method to save their lives. |
What do you need to know before this surgery?
This is not a major surgery, but a minor procedure. But before that, you should talk openly with your doctor about your patient's health condition.
- Be sure to mention any existing illnesses, such as heart disease and diabetes.
- Medications: If you are taking blood thinners (e.g. `Warfarin`, `Aspirin`, `Clopidogrel`) or painkillers that fall into the ``NSAIDs`` category (e.g. `Ibuprofen`), you should tell your doctor. They will ask you to stop taking these a few days before the surgery. This is because these medications increase the risk of bleeding.
- Allergies: If you have any allergies to any medication, please mention them.
Do not eat or drink anything for about 8 hours before the surgery. It is also important to arrange a vehicle to get home from the hospital.
What actually happens when a PEG tube is inserted?
This procedure takes about 20-30 minutes. Necessary steps are taken to keep the patient comfortable during this time.
1. Anesthesia: First, the patient is put into a light sleep by means of intravenous anesthesia. Therefore, no pain or discomfort is felt. Antibiotics are also given at this time to prevent infection.
2. Local anesthesia: A small injection (local anesthetic) is given to numb the area around the skin of the abdomen where the tube will be inserted.
3. Inserting the endoscope: The doctor will now insert a small tube (endoscope) with a camera attached through the mouth and into the stomach. This allows the inside of the stomach to be seen clearly.
4. Incision and tube insertion: The light from the endoscope is seen through the skin of the abdomen. Looking at that light, the doctor makes a small incision in the skin, about a centimeter in the exact same spot. Then, through that incision, the PEG tube is inserted into the stomach and secured.
This may sound a little scary, but remember that the patient will not feel anything. It is also a very safe and common procedure.
Most of the time, you can go home the same evening or the next morning.
What to expect after surgery?
It is normal to feel some pain after surgery. You may feel a sensation of pain or a feeling of fullness in your abdomen where the incision was made. This pain will subside within 24-48 hours.
- Wound: A small bandage will be placed over the incision. It is normal for a little fluid to ooze for the first two days. The doctor will advise you to remove the bandage after about two days.
- Nutrition: Liquid feedings will begin shortly after the tube is inserted. A dietitian will educate you on how to do this, what type of nutritional fluid to give, and how many times a day to give it.
- Tube Appearance: Yes, part of the tube is outside the body. It is usually a tube about the thickness of a pencil and about 6-12 inches long. There is a small disc-like part (`external bumper`) on the skin surface to prevent the tube from going back in. The end of the tube is covered with a small cap. This prevents stomach acid from coming out. This cap can be opened when food, water, or medicine need to be given.
Are there risks and complications?
As with any medical procedure, there are small risks. However, these are rare. Proper cleaning and care of the tube can greatly reduce these risks.
| Risk/Complexity | Things you need to pay attention to |
|---|---|
| Infection | Redness, swelling, warmth, pus, or fever around the tube. |
| Bleeding | Bleeding around the tube or inside the stomach. |
| Leakage around the pipe | Stomach contents leaking out through the tube and skin. |
| Dislodgement | The tube suddenly comes off completely. This is an emergency! |
| Aspiration | Stomach contents going into the lungs. To prevent this, it is important to keep the patient's head elevated when feeding. |
How to care for a PEG tube?
It is very important to keep the skin around the tube clean every day.
- First, wash your hands thoroughly with soap.
- Then, soak a clean cloth or piece of gauze in soapy water and gently clean the skin around the tube.
- Rinse again with clean water to remove the soap.
- Finally, let it dry thoroughly. Do not apply any creams or powders without the advice of a doctor.
Some frequently asked questions
Can someone with a PEG tube eat and drink by mouth?
This depends on the underlying medical condition that caused the tube to be inserted. If the tube was inserted because of difficulty swallowing, food and drink intake by mouth will be restricted, as this can cause the food to re-enter the lungs. However, some people may be allowed to eat small amounts by mouth by their doctor. Ask your doctor about this to be sure.
How long should I keep this tube?
A PEG tube can be used for months or even years. Over time, the tube can become discolored or blocked. If the tube changes color, leaks fluid, or appears lumpy, it's time to replace it. Inserting a new tube is very simple, and does not require anesthesia or surgery. If the patient's condition improves and they can swallow again, the tube can be removed completely. The hole in the stomach will then close on its own within a few days.
What do you do if the tube suddenly comes off?
This is an emergency. You need to go to a hospital, the Emergency Treatment Unit (ETU) immediately. Because the hole in the stomach and skin will start to close within a few hours. If that happens, it will be difficult to put a new tube in. Therefore, if the tube comes out, it is essential to seek medical attention within 24 hours .
A PEG tube is a very important medical device that can save a person's life, prevent nutritional deficiencies, and improve their quality of life. The most important thing is to not be afraid of it, to understand it correctly, and to take proper care of it.
