There are several options:
Nasogastric or nasojejunal. If you need tube feeding for less than one to three months, Mayo doctors usually recommend
inserting the tube through the nose and into the stomach (nasogastric placement) or into the jejunum — the middle part of the small intestine (nasojejunal placement).
Stomach. If you need long-term tube feeding and your stomach functions normally, the tube may be placed through the
skin of the abdominal wall into the stomach (percutaneous endoscopic gastrostomy). Tubes may also be inserted using
radiologic image guidance or surgery. Minimally invasive (laparoscopic) surgery is sometimes possible.
Intestine. If your stomach doesn’t function normally, the tube may be inserted into the jejunum. Tubes may be inserted by
endoscope or by laparoscopic or open surgery.
Intestinal tube feeding is also generally recommended for people with:
Altered mental status who cannot eat normally
Bolus. A syringe delivers liquid nutrients into the stomach for five to 10 minutes several times a day.
Gravity. A gravity-assisted drip delivers liquid nutrients into the stomach. Feeding is usually done for 45 to 60 minutes two
or four times a day.
Continuous. A pump delivers liquid nutrients at a constant rate. Continuous feeding is usually needed for intestinal tube feeding and may be used overnight.
