Gastrostomy Tubes (PEG Tubes): Cat Kidney Disease Glossary

Gastrostomy Tubes (PEG Tubes) A Gastrostomy Tube (commonly called a PEG tube) is a feeding tube placed directly through the abdominal wall into the stomach. In the context of the Chronic Kidney Disease (CKD) cat, this is the most permanent and robust solution for long-term nutritional support, though it is less common than the E-Tube due to the complexity of placement.

The "Direct Route" Mechanism

Placement: "PEG" stands for Percutaneous Endoscopic Gastrostomy. The vet uses an endoscope (a camera down the throat) to guide a needle through the belly wall and pull the tube into place. It requires full anesthesia.
Location: The tube exits the side of the cat's belly.
The Advantage: Because it bypasses the esophagus entirely, it is useful if the cat has esophageal issues (like strictures or megaesophagus) that make an E-Tube impossible.

Durability & Lifestyle

The "Permanent" Solution: PEG tubes are extremely durable. They are designed to stay in for months to years.
Body Suit: Unlike the neck tube which requires a collar, a PEG tube requires the cat to wear a "Stockinette" or a recovery suit (like a baby onesie) to keep the tube flat against the body and prevent it from getting snagged.
Activity: Once healed, it interferes very little with the cat's movement, though they cannot go outside or jump through tight spaces where the tube might catch.

The "2-Week" Safety Rule This is the most critical danger of a PEG tube.

Adhesion: It takes about 10–14 days for the stomach to heal and fuse to the abdominal wall.
The Risk: If the tube is pulled out or dislodged during these first two weeks, the stomach creates a hole inside the belly. Food and stomach acid will leak directly into the abdomen, causing Septic Peritonitis, which is rapidly fatal.
The Constraint: You cannot remove or replace a PEG tube casually. It requires veterinary intervention.

PEG vs. E-Tube (Comparison)

E-Tube (Neck): Easier to place, easier to remove, requires only light anesthesia. Best for most CKD cats.
PEG (Stomach): Harder to place, riskier to remove, requires specialized equipment (endoscope). Usually reserved for cats who cannot have an E-Tube or need permanent, lifelong support.

Low Profile Buttons

The Upgrade: After the initial long tube has healed (usually after a few months), it can sometimes be replaced with a "Low Profile Button."
The Look: This sits flush against the skin (like a valve), removing the dangling tube entirely. You simply snap a feeding line into the button when it's mealtime and disconnect it when done.
