The gastrostomy tube, or the G-tube as it is usually called, delivers nutrition directly to the stomach through an insertion in the abdomen.
These are temporary tubes that don’t require surgery to be inserted. Nasogastric (NG) tubes run from the nose, down the esophagus, and into the stomach. Nasoduodenal (ND) tubes run from the nose to the stomach, ending in the first part of the small intestine. Nasojejunal (NJ) tubes extend into the second portion of the small intestine, the jejunum.
The gastrostomy-jejunostomy (GJ) tube accesses both the stomach and small intestine.
The jejunostomy (J) tube is placed in the middle of the small intestine, called the jejunum, through an insertion in the skin of the abdomen.
Once you know what type of feeding tube you will require, you will need to choose a pump. A feeding pump infuses formula into the feeding tube in a slow, metered fashion. Most pumps will work with any type of feeding tube as long as you have the necessary supplies.
Enteral feeding formulas are “nutritionally complete,” meaning they’re designed to give you all the nutrients — protein, carbohydrates, fats, vitamins, and minerals — you need to live and grow. There are thousands of enteral formulas available. A patient’s medical condition will determine the exact proportion of nutrients needed. In addition, some formulas are designed to be used with feeding tubes, and some are designed to be taken orally. You are therefore advised to speak with your doctor before visiting a medical supply store, so that you will not be overwhelmed with the available options.
