Gastrostomy management

A gastrostomy is a feeding tube that is inserted directly into the stomach either surgically under direct vision (open or laproscopic), endoscopically (with a camera), or radiologically (x-ray guidance). A gastrostomy tube allows the delivery of supplemental nutrition and medications directly into the stomach. It also provides a mechanism to drain gastric contents if required. In order for gastrostomy feeding to be successful the child or young person must have a functioning gastrointestinal tract.
