From the image you provided, the G-tube does appear to be somewhat deformed. It still appears to be patent. Is your husband still able to receive infusions through the tube? If so, what is the diameter of French (Fr) measurement of the tube?

It appears that the tube deformities apparent in your picture are consistent with repeated physical deformation of the tube, perhaps related to folding, pinching or kinking the tube or the use of a metal hemostat or clamp to stop outflow of infused fluids while switching between catheter tipped syringes or feeding bags.

Where and how often do you or your husband clamp the G-tube when you need to perform infusions? You should use a plastic hemostat to clamp off the tube as it will not damage or deform the soft tubing.

Of course it could be that the current tube inserted is defective but I doubt that they would place a defective tube.

If the tube continues to deteriorate becomes occluded or has reduced flow, it should be replaced.
