The most common type of feeding tube is the gastrostomy (G) tube. G-tubes are placed through the abdominal wall into the stomach. This sounds scarier than it is. The G-tube surgery can be performed in three ways: surgically through small incisions using a laparoscope, surgically using a larger open incision, or endoscopically using a scope into the stomach to create the stoma from the inside ...
Most GJ-tubes have separate ports to access both the stomach (G-port) and the small intestine (J-port), though some tubes, often called Transjejunal (TJ) tubes, only allow access to the small intestine. GJ-tubes are available both as buttons or long tubes.
GJ-tubes are placed in the stomach just like G-tubes, but a thin, long tube is threaded into the jejunal (J) portion of the small intestine. The vast majority of children who get GJ feeding tubes begin with G-tubes; it is rare for a GJ-tube to be placed initially.
The choice between nasogastric (NG), nasoduodenal (ND), and nasojejunal (NJ) tubes depends on whether your child can tolerate feeding into the stomach or not. NG-tubes NG-tubes enter the body through the nose and run down the esophagus into the stomach.
