Although there are reports of blind passage of NJ tubes at the bedside, the success rate is often not replicated in clinical practice. NJ tubes are thus placed either endoscopically or radiologically.
Nasojejunal tubes are smaller than nasogastric tubes and are thus more prone to kinking and blockages. Thus 10 or 12 F tunes are preferred.
Types:
Freka® Endolumina Nasojejunal Feeding Tube
8F tube- it can be passed through the biopsy channel of the scope. The proximal end of the tube is backloaded from the oral cavity into the nasal cavity using a nasal transfer tube
Corflo ® Nasojejunal Feeding Tubes
10F or 12 F. This cannot be passed through the scope (not TTS)
Flocare Bengmark Naso-Intestinal Tube
8F or 10F
It has a terminal spiral (this is kept straight by the guideline to aid insertion) which helps in spontaneous passage through the pylorus in 8-12 hours, if placed blindly. This tube can also be passed endoscopically or radiologically
Freka® CH9 Intestinal Tube for CH15 PEG
This is a 9F extension tube which can inserted in the jejunum endoscopically via the PEG tube.
