A gastrostomy feeding button serves as an alternative feeding device for an ambulatory patient who is receiving long-term enteral feedings. Approved by the Food and Drug Administration for 6-month implantation, feeding buttons can be used to replace gastrostomy tubes, if necessary.

The button has a mushroom dome at one end and two wing tabs and a flexible safety plug at the other. When inserted into an established stoma, the button lies almost flush with the skin, with only the wings and the top of the safety plug visible.

The button can usually be inserted into a stoma in less than 15 minutes. Besides its cosmetic appeal, the device is easily maintained, reduces skin irritation and breakdown, and is less likely to become dislodged or migrate than an ordinary feeding tube. A one-way, antireflux valve mounted just inside the mushroom dome prevents accidental leakage of gastric contents. The device usually requires replacement after 3 to 4 months, typically because the antireflux valve wears out.
