Can a PEG tube present in the stomach cause harm?

Question

Hello doctor,

If a PEG (percutaneous endoscopic gastrostomy) tube material, which is significantly degraded in the stomach, is being metabolized by the body to assess whether it serves as fuel or waste, it poses a risk to the system. I realize that the material is inert if ingested and excreted. Please tell me, is there a term for it becoming toxic or something similar if it remains long enough to break down into mush?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

The body does not metabolize the material of PEG (percutaneous endoscopic gastrostomy) tubes, and if it begins to degrade or break down, it does not transform into poison or get absorbed as a toxin.

PEG tubes are constructed from medical-grade silicone or polyurethane, which are biochemically inert, indicating that your body does not digest, absorb, or metabolize them. Typically, they withstand stomach acid effectively. However, over time, due to exposure to acid and digestive enzymes, the tube may soften, discolor, or crumble, resembling rotting material. This phenomenon is mechanical degradation rather than chemical poisoning.

Even if a small degraded fragment enters the stomach, it generally passes through the intestines and exits the body without causing harm. Nevertheless, a tube that is deteriorating should be replaced promptly, as fragments can obstruct the tube, lead to infection, or disrupt proper feeding.

However, it is not toxic, but it is unsafe to leave a degraded tube in place. The appropriate course of action is to consult with your gastroenterologist or interventional radiologist for tube replacement and inspection.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
