G-tube Tips from Dr. Julie Sanchez

Posted by Julie Sanchez on

Dr. Julie Sanchez, Pediatric Surgeon and co-founder of Spoonie Threads, shares her insight for parents working with g-tubes (also known as g-buttons or Mic-Keys) on their little ones.


Read on for more info, and share your questions for Dr. Sanchez in the blog comments below!

Q: How often should a g-tube be changed?

Dr. Sanchez : Most g-buttons should be changed out every 6 months and usually upsized once a year. 


Q: Do you recommend venting the b-gutton? 

Dr. Sanchez: Venting before feeds can help your child tolerate his feed better, especially if your child has a fundoplication or a wrap.  


Q: My son pulled out his g-tube and I see discoloration in the balloon? Can I put it back in or is it normal due to stomach contents. 

Dr. Sanchez: If you check the water in the balloon and it's discolored, it likely has a leak. I recommend changing out the g-button. Read more about how to prevent leaking here. I remind parents to keep the site dry and tubes secured with the snaps. Most g-buttons are accidently pulled out by caregivers. 


Q: What to do about developed Granulation Tissue?


Dr. Sanchez: The surrounding skin around granulation tissue is fragile and can ooze, bleed, drain, or cause the button to have a poor fit and leak. It is important to keep a properly fit G-button in place to prevent granulation tissue. There are many ways to treat granulation tissue from ointments to cauterization. A G-tube pad can help absorb some of the drainage and provide comfort. Again, it is important for the pad to be kept dry and change the pad when it is wet or moist to prevent further skin breakdown.
