What am I looking at?
Visual recognition
Long enteral tube with separate gastric and jejunal ports, extending beyond the stomach so the distal limb can terminate in the proximal jejunum.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Tube entering the stomach with its tip advanced through the pylorus into the jejunum, delivering post-pyloric feeds while allowing simultaneous gastric decompression. Typical procedural contexts include aspiration risk, gastroparesis, and gastric-outlet obstruction requiring post-pyloric feeding.
What most clearly distinguishes it from similar devices?
Key distinctions
A GJ tube provides separate gastric and jejunal access, with the feeding limb extending beyond the pylorus; this distinguishes it from a gastrostomy tube that terminates in the stomach.
