The gastrostomy "button"--a simple, skin-level, nonrefluxing device for long-term enteral feedings

In an effort to eliminate the common problems associated with gastrostomy tubes in children, we developed a silicone rubber gastrostomy "button" designed to replace the standard long latex tube. Easily inserted and self-retaining, the device remains practically flush with the skin. The intragastric portion is similar to a dePezzer catheter, and a one-way valve prevents reflux of gastric contents. Prototypes were evaluated in five children for a time period of 3 to 18 months. In two additional patients with esophageal stricture, the device was used as a temporary plug to maintain gastric stoma patency. Parents and nurses are pleased with the button's low profile, appearance, and ease to use. It is neither painful nor irritating, and there is no fear of dislodgement.
