What is Gastrostomy?
A gastrostomy is a small device (often called a button) which passes directly into the stomach through the abdomen (belly). This tube allows parents and caregivers to provide essential nutrition, fluids, and medications without needing to rely on oral feeding. It is often used as a long-term alternative to a nasogastric tube in children who cannot safely swallow enough food to be able to grow.
The goal of a gastrostomy is to ensure your child receives the necessary nourishment to support their growth and development in a safe and effective way.
Is a Gastrostomy the Same as PEG?
Not quite. A PEG is a Percutaneous (through the skin) Endoscopic (telescope into the stomach) Gastrostomy. PEG refers to a technique of placing a gastrostomy, and not to the gastrostomy itself. The terms PEG, gastrostomy, and button are often used as if they are the same, but they aren’t.
A gastrostomy is pathway into the stomach through the abdominal wall. A PEG is one way of forming a gastrostomy (there are others). Once formed, something needs to be placed in the gastrostomy to prevent it from closing (like studs after ears are pierced). That something might be a button, or it might be a tube.
Formation of Surgical Gastrostomy In Children
We do not perform PEGs; we perform surgical gastrostomies. Gastrostomy surgery is a procedure performed under general anaesthetic. The surgeon uses laparoscopy (keyhole surgery) to find the stomach, and secure it to the abdominal wall. The feeding device (a gastrostomy button or tube) is then placed into the stomach through the opening.
The wound is closed with dissolvable sutures, and there are sutures that hold the button in place for 1-2 weeks.
After the procedure, your child will be in the recovery room for monitoring, and you will be able to join them shortly after they wake up.
Education is required before the operation, and support is required afterwards. We often work with the team at Children’s Nursing Queensland for this service. Please note there is a fee for their service, although this might be covered by your child’s NDIS package.
How Long Does the Operation Take?
The surgery itself takes around 30 minutes, but the overall process, including anaesthetic time, and waking up in recovery, can last well over an hour depending on the condition of the child.
Often, a family adult can be in the operating room with your child as they are anaesthetised. Family members cannot stay for the operation itself. You will be away from your child until they are ready to be seen in the recovery room.
You’ll be notified just as they are waking up so you can be with them as early as possible.
What Are the Risks of the Operation?
Like any surgery, forming a gastrostomy comes with some risks. However, the surgery is straightforward and serious complications are very rare.
- Anaesthetic Risks: Airway and breathing issues are extremely rare.
- Bowel Injury: In rare cases there is injury to the bowel or stomach, which may require further surgery.
- Infection: The risk of infection is around 15%. There is much care and attention required after surgery.
- Conversion: Very rarely, it is too difficult or dangerous to complete the operation laparoscopically. If this occurs your child will have a small vertical incision in the upper abdomen. They may have a tube, rather than a button, for the first few months after this operation.
- Leaking: In the initial few months, it is very common to have some leaking from the stomach. This can be annoying, and cause irritation of the surrounding skin.
- Bleeding, Bruising, and Swelling: These are common minor side effects of surgery and typically resolve without issue.
- Granulation tissue: In some cases, there is overgrowth of healing tissue at the site of the button, which can bleed and have a yellow / cream discharge. This may need topical treatment, and occasionally requires a small visit to the operating room for removal.
What to Expect After Surgery
Once the surgery is complete, your child will be taken to the recovery room. You will be able to join them shortly after they wake up. Most children recover quickly from anaesthesia.
Feeding plans are made with you and your treating team. The stomach will need some rest for a few hours, and if your child has a nasogastric tube already then we will be able to check safety before starting feeds.
Your child can usually go home with you the day after surgery, once the nursing team ensures they are feeding well, comfortable, and safe.
Caring for the Wound and Dressings
After surgery, there will be dressings over the incision sites (the umbilicus and the gastrostomy itself). The area may become a bit swollen or firm, which is a normal part of the healing process as scar tissue forms. The scar will initially appear dark red but will fade over time.
Removing the dressing: The dressing can be removed in the bath or shower after one week. This is usually done with the stomal therapy nurses.
Bruising and Swelling: It is normal to see some bruising and swelling around the incision site. This should improve within a few days.
Pain Relief After Surgery
Your child will receive good pain relief during the operation, and this should last for a few hours afterward. Once at home, you will need to give your child paracetamol (e.g., Panadol) and possibly ibuprofen (e.g., Nurofen) for a few days. Your child may have other conditions that require a different regime for medications. Please let your surgeon and anaesthetist know if your child has intolerances or allergies to particular medications.
It’s also helpful to distract your child and keep their mind off the surgery site. Activities like reading, playing board games, or other quiet, engaging tasks can help ease discomfort and take their mind off the area.
When Can My Child Return to Normal Activities?
Your child can return to normal daily activities fairly quickly after surgery, but some restrictions will apply:
- Bath or Shower: After a few days. They will need sponge baths in the meantime.
- Swimming: Usually after 1 week, however this is planned with the surgeon and the stomal therapy nurses.
- Daycare/School: We will make a plan with you depending on the needs of your child.
- Sports or Physical Activity: We will plan this based on any special needs for your child.
Troubleshooting Common Concerns After Surgery
Is there a wound infection?
Infections are uncommon but can occur 2-4 days after surgery. Signs of infection include:
- Increased redness or tenderness around the wound.
- Discharge from the wound site.
- Fever or general unwellness.
If you notice these signs, contact your paediatric surgeon or family doctor for further advice.
Has the button dislodged?
Some swelling is normal after surgery, but if your child experiences increasing pain, tenderness, or vomiting, this could be a sign the button may have been dislodged or pulled out by accident.
If the button falls out completely place a simple dressing over the hole.
These issues require urgent attention. Either contact your surgeon or go to the emergency department. Do not wait until the next day, as the hole closes over very quickly and it becomes increasingly difficult to replace the button as time passes
After surgery, what symptoms might be cause for concern?
You know your child best, and if something doesn’t seem right, it’s always best to seek advice. Here are some key symptoms that require medical attention:
- Increasing pain or pain that doesn’t improve with pain relief.
- A new or increasing bulge in the area.
- Fever over 38.2°C.
- Vomiting or trouble feeding.
- No bowel movements after three days.
- Any discharge or bleeding from the wound.
- The button fell out.
If you notice any of these symptoms, contact your surgeon or family doctor.
