Gastric Tubes (or G-tubes): The most common type of feeding tube is the gastrostomy (G) tube. G-tubes are surgically placed through the abdominal wall into the stomach. There are a number of types of G-tubes. Any kind of G-tube can be placed initially. Often it is the surgeon or the gastroenterologist who determines the first type of G-tube placed. These are some of the most common types of G-tubes you may encounter.
The longer internal tube allows feeding directly into the intestine for children and adults who cannot tolerate gastric feeds. GJ-tubes are rarely a first tube. In most cases, a G-tube is converted to a GJ-tube when gastric feedings are not tolerated. Both long GJ-tubes and skin-level button devices are available.
Allowing the introduction of oral feeding is a further advantage of nasoenteral feeding, and the nasal route makes for easier insertion. Nasogastric tube feeding. The majority of patients requiring nutritional support will need it for less than one month, and nasogastric tube feeding is by far the most commonly used route of access.
Nasogastric and nasoenteric tubes are flexible double or single lumen tubes that are passed proximally from the nose distally into the stomach or small bowel. Enteric tubes that will be removed within a short period of time can also be passed through the mouth (orogastric).
