Discharge Instructions: Caring for Your Jejunostomy Tube (J-Tube)

You have been discharged with a feeding tube called a jejunostomy tube, or J-tube. The J-tube was put through your skin and into your small bowel (jejunum). This allows for feeding directly into your small bowel. Your feeding tube was put in because you are not able to take in enough food or drink through your mouth to keep your normal body weight. You were shown how to care for your J-tube in the hospital. This sheet helps you remember the steps when you’re at home.

Guidelines for continuous tube feeding

  • Make arrangements for a special feeding pump to be delivered to your home.

  • Do not take medicines through your J-tube.

  • Keep tension off the tubing by taping it up onto your belly (abdomen).

Clean around the tube

  • Wash your hands thoroughly with mild soap and water before starting your feeding.

  • Clean the area around the tube with mild soap and water.

  • Pat the area dry using a clean washcloth.

Get ready

  • Assemble the supplies you will need. These include formula, water, feeding bag, pump, and a 30 to 60 mL syringe.

  • Close the clamp on the feeding bag tubing.

  • Slowly pour the formula into the feeding bag. Use the prescribed amount of feeding.

  • Hang the feeding bag on the pole about 1 to 2 feet above your head.

Begin feeding

  • Open the clamp and let the formula fill the entire tubing, clearing any air.

  • Close the clamp.

  • Connect the feeding bag tubing to the pump. Adjust the settings on the pump.

  • Using the syringe, flush the J-tube with the prescribed amount of water.

  • Connect the tubing of the feeding bag to the J-tube.

  • Open the clamp. Start the pump.

After the feeding

  • When the feeding is finished, stop the infusion and flush the J-tube with the prescribed amount of water.

  • Stop the feeding once each day to clean the bag. Wash the feeding bag with soapy water.

  • Rinse the bag thoroughly so that there is no soapy film in the bag. Hang the bag to dry.

  • Flush the J-tube with the prescribed amount of water every 4 to 6 hours through the flush port. If there is no flush port, do this: Stop the pump, disconnect the feeding bag tubing, and flush the J-tube.
