Percutaneous Endoscopic Jejunostomy (PEJ) Tube Care and Management
A Percutaneous Endoscopic Jejunostomy (PEJ) tube delivers essential nutrition, fluids, and medications directly into the small intestine when gastric feeding is unsafe or not tolerated. Proper maintenance requires continuous infusion techniques, strict hygiene, and routine site assessments to prevent infection and tube blockage. This guide outlines standard protocols for daily site care, flushing routines, medication administration, and troubleshooting complications.
Quick Summary
Maintain your PEJ tube by using an infusion pump for continuous feeds, flushing regularly with warm water, and seeking immediate emergency care if the tube becomes dislodged.

Step-by-Step Guide
Prepare Equipment and Sanitize
Wash your hands thoroughly with antibacterial soap and warm water for at least 20 seconds, drying them with a clean paper towel. Assemble your prescribed enteral formula, clean 60 mL ENFit syringes, room-temperature sterile or purified water, and an electronic infusion pump. Check formula expiration dates, verify tube labeling to prevent misconnections, and prepare a clean, sanitized work surface.
Inspect and Clean the Stoma Site
Gently lift the retention bolster if loose, inspecting the surrounding peristomal skin daily for redness, swelling, unusual odor, formula leakage, or hypergranulation tissue. Clean the skin using sterile water or mild soap on sterile gauze or cotton-tipped applicators, moving outward from the stoma in concentric circles. Pat the area completely dry with clean gauze, leaving it exposed to air unless your clinician prescribed a split drain sponge for discharge.
Important: Unlike standard G-tubes, never vigorously twist or rotate a PEJ tube unless specifically instructed by your gastroenterologist, as twisting can cause internal bowel torsion or malposition.
Flush the Tube with Water
Draw up 20 to 30 mL of room-temperature purified or sterile water into an enteral-specific 60 mL syringe. Connect the syringe firmly to the designated flush port, unclamp the line, and instill the water using a gentle, steady push-pause method. Flush your PEJ tube before and after every feed, before and after every medication, and every 4 to 6 hours during continuous feeding.
Important: Never use small syringes (under 30 mL) or force fluid against resistance, as high pressure can rupture the jejunal tube or cause intestinal injury.
Administer Feeding via Infusion Pump
Prime the enteral administration set with formula to remove air bubbles, then load the tubing into the infusion pump. Connect the feeding set to the jejunal port and configure the pump strictly to the prescribed hourly rate and total volume. Maintain the patient's head of bed elevated at a minimum 30- to 45-degree angle during feeding and for at least 30 minutes afterward to prevent reflux.
Important: Never deliver bolus or gravity feedings directly into a PEJ tube; the small intestine lacks a reservoir and rapid infusion can cause life-threatening dumping syndrome, severe cramping, and diarrhea.
Administer Medications Safely
Ensure all medications are compatible with jejunal delivery and prefer liquid formulations whenever available. If crushing tablets is approved by a pharmacist, crush them to a fine powder and dissolve each medication individually in 15 to 30 mL of warm water. Administer each medication separately, flushing the tube with 10 to 15 mL of warm water between each drug and a final flush of 30 mL at the end.
Important: Never crush enteric-coated, delayed-release, or sustained-release medications, as doing so alters pharmacokinetics and can permanently block the small-bore jejunal tube.
Secure the Line and Monitor for Complications
Secure the external tubing to the abdominal wall using a dedicated catheter stabilization device or skin-friendly medical tape, leaving enough slack to prevent tension. Check external markings daily at the skin level to verify that the tube has not migrated outward or inward. Regularly monitor for signs of systemic complications, including fever, persistent abdominal distension, severe pain, or bleeding.
Important: If your PEJ tube is accidentally pulled out or dislodged, cover the stoma with a clean dressing and go to an emergency department immediately; jejunal tracts can close completely within 2 to 4 hours.
