Fluoroscopic nasojejunal (NJT) or nasogastric tube (NGT) insertion is a valuable procedure offered by Interventional radiologists in patient care.
The majority of nasogastric tubes are inserted on the ward level and nasojejunal tubes may be placed in theatre at the time of surgery.
In difficult cases, tube insertion is undertaken under fluoroscopic guidance.
Together with the use of water-soluble contrast media and over-the-wire technique, fluoroscopy-guided placement of nasogastric or nasojejunal feeding tubes offers a higher rate of technical success while decreasing procedure time as well as the incidence of procedure-related complications.
In the case of a nasojejunal tube, the tip position at or beyond the duodenojejunal flexure (ligament of Treitz) is desirable. It may move further distally over time with peristalsis.
