Surgical feeding tubes are medically necessary for individuals with conditions that prevent or hinder oral consumption. These devices, collectively known as enteral feeding tubes, are placed directly into the gastrointestinal tract through an incision in the abdomen. The specific name of the tube depends on its final destination within the digestive system.
The Different Names for Surgical Feeding Tubes
Several terms are used to describe surgically placed feeding tubes, reflecting their specific type and placement method. The most common types include:
- Gastrostomy Tube (G-tube): This is a general term for a feeding tube that goes directly into the stomach through an incision in the abdomen.
- Percutaneous Endoscopic Gastrostomy (PEG) Tube: A PEG is a specific type of G-tube inserted with the aid of an endoscope, a flexible tube with a camera. It is often considered a less invasive alternative to open surgery.
- Jejunostomy Tube (J-tube): Unlike a G-tube, a J-tube bypasses the stomach and is inserted directly into the jejunum, the middle section of the small intestine. This is used when feeding into the stomach is not possible or not tolerated.
- Radiologically Inserted Gastrostomy (RIG) Tube: Similar to a PEG, a RIG tube is placed through the skin into the stomach, but it uses radiological guidance (X-rays) instead of an endoscope.
- Gastro-Jejunostomy (GJ) Tube: This tube has two lumens, allowing access to both the stomach (for draining or medication) and the jejunum (for feeding).
Why are surgical feeding tubes needed?
Physicians may recommend a surgically placed feeding tube for various reasons, particularly for long-term nutritional support. These include:
- Difficulty Swallowing (Dysphagia): Conditions like stroke, head or neck cancers, or neurological disorders can make swallowing unsafe, leading to a risk of aspiration.
- Malnutrition or Failure to Thrive: For patients who cannot consume enough nutrients orally to maintain a healthy weight.
- Certain Gastrointestinal Disorders: When a condition interferes with the stomach's ability to receive or empty food, such as severe reflux or gastric outlet obstruction.
- Pre-existing Medical Conditions: In cases involving severe burns, cystic fibrosis, or after major gastrointestinal surgery.
Comparison of PEG and J-Tubes
Selecting the right type of surgical feeding tube is a decision made by a healthcare team based on a patient's specific medical needs. Here is a comparison of two common types:
| Feature | Percutaneous Endoscopic Gastrostomy (PEG) Tube | Jejunostomy (J-Tube) |
|---|---|---|
| Placement Site | Stomach | Jejunum (small intestine) |
| Placement Method | Endoscopically, through the abdominal wall | Surgically (laparoscopic or open) or endoscopically |
| Feeding Schedule | Can be fed in boluses (larger amounts at intervals) or continuously | Requires slow, continuous drip feeding via a pump, as the small intestine cannot store food like the stomach |
| Bypasses Stomach? | No | Yes |
| Common Use Cases | Swallowing difficulties, head/neck cancer, stroke | Gastric motility issues, severe reflux, stomach-related surgery |
Potential Complications and Daily Care
While surgical feeding tubes are generally safe, proper care is essential to prevent complications. Some potential issues include:
- Infection: Redness, swelling, or pain at the insertion (stoma) site.
- Leakage: Digestive fluid leaking from the stoma site, which can irritate the skin.
- Tube Dislodgement: The tube can accidentally come out, requiring immediate medical attention to prevent the stoma from closing.
- Blockage: The tube can become clogged with formula or medications if not flushed properly.
- Gastrointestinal Distress: Nausea, vomiting, diarrhea, or constipation can occur.
To ensure proper function and minimize risks, daily care is crucial:
- Hand Hygiene: Always wash your hands thoroughly before touching the tube or stoma site.
- Stoma Site Care: Clean the skin around the tube twice daily with soap and water, and dry it completely.
- Flushing: Flush the tube with warm water before and after each feeding or medication administration to prevent clogs.
- Securing the Tube: Secure the external tubing to the abdomen to prevent pulling or kinking.
- Monitoring: Regularly check the stoma site for signs of infection or leakage.
Conclusion
A surgical feeding tube, commonly known as a G-tube, PEG, or J-tube, is a vital medical device for providing long-term nutritional support. The specific type chosen depends on the patient's condition and the required access point in the digestive tract. With proper care and monitoring, these tubes enable individuals who cannot eat or swallow safely to maintain their health and quality of life. Patients and caregivers should work closely with their healthcare team to understand the procedure, manage daily care routines, and address any potential complications.

What is a surgical feeding tube called? Key Takeaways
- Gastrostomy (G-tube): A general term for a surgically placed feeding tube that leads directly into the stomach.
- PEG Tube Placement: A specific, less-invasive method of placing a G-tube using an endoscope.
- Jejunostomy (J-tube): A tube placed directly into the small intestine, used when stomach feeding is not an option.
- Preventing Complications: Proper hygiene, regular flushing, and site care are essential to avoid infections and blockages.
- Long-Term Solution: Surgical feeding tubes are typically intended for long-term use (more than 6 weeks) and are more durable than temporary nasal tubes.
FAQs
Question: What is the main difference between a G-tube and a PEG tube? Answer: A G-tube is a general term for a tube placed in the stomach. A PEG tube is a type of G-tube that is inserted using a specific, less-invasive endoscopic procedure.
Question: When is a J-tube used instead of a G-tube? Answer: A J-tube is used when the stomach is not a suitable access point for feeding, such as with severe reflux or impaired gastric emptying, requiring direct delivery to the small intestine.
Question: What is a low-profile feeding tube? Answer: A low-profile tube, or 'button', is a type of gastrostomy or jejunostomy tube that sits flat against the skin. It is often more discreet and can be more comfortable for active patients.
Question: How long does a surgical feeding tube stay in place? Answer: Surgically placed feeding tubes are typically for long-term use (more than six weeks), and some patients may require them indefinitely. They can be replaced as needed by a healthcare professional.
Question: What are the most common signs of infection at the tube site? Answer: Signs of infection include redness, increased drainage (especially if it's yellow or green), swelling, increased pain, or fever. You should contact a healthcare provider if these symptoms appear.
Question: Can a feeding tube become clogged, and how can it be prevented? Answer: Yes, feeding tubes can become clogged. Prevention involves flushing the tube with warm water before and after each feeding and medication dose. Avoid using sharp objects to clear a blockage.
Question: Is it possible to eat by mouth with a feeding tube? Answer: In many cases, yes. Your healthcare provider or dietitian will determine if it is safe to continue eating and drinking orally. The tube may be used to supplement nutritional intake rather than replace it entirely.
