J Tubes

Jejunostomy (J) Tube

J tubes are a long-term option that go through both the abdomen and the stomach, and then continues into the part of the small intestine called the jejunum.

A few different scenarios require a person to get a J tube instead of a G tube. Doctors may also suggest J tubes for people with slowed digestion to prevent reflux or other issues that a direct-to-stomach tube might cause.

Like G tubes, J tubes have the flexibility of serving as either a standard-length tube (“dangler”) or a low-profile, button tube. J tubes are placed through various surgical procedures. Because the tube extends down into the small intestine, these tubes cannot be replaced at home.

MIC-KEY* J Tube

This low-profile tube, sometimes called a “button,” uses an extension set that can be detached when not in use that allows it to be easily hidden under clothing.

MIC* J Tube

This is a standard-length tube, sometimes called a “dangler.”

MIC-KEY* Continuous Extension Set

The extension set attaches to any MIC-KEY* feeding tube when nutrition, fluids, or medication needs to be given. Continuous sets are used when feeding small amounts constantly throughout the day (or night) without interruption.
