Management of Acute Gastrostomy Tube Dislodgement with Foley Catheter
For a mature tract (>4 weeks), immediately insert a Foley catheter of the same size to maintain tract patency, then replace with a proper gastrostomy tube as soon as possible—ideally within hours to days. 1
Immediate Action Based on Tract Maturity
Mature Tract (>4 Weeks Post-Placement)
- Insert a Foley catheter immediately to prevent tract closure, which can occur within hours 1
- Use the same French size as the original gastrostomy tube 1
- Inflate the balloon with 5-10 mL sterile water once positioned 1
- This is a temporary measure only—replace with a dedicated gastrostomy tube as quickly as possible 1, 2
Immature Tract (<4 Weeks Post-Placement)
- This is an emergency—do NOT attempt blind replacement 1, 3
- Requires endoscopic or radiologic replacement to prevent intraperitoneal placement and peritonitis 1, 3
- Between 2-4 weeks: blind replacement may be attempted only with mandatory water-soluble contrast confirmation afterward 1
- In the first 2 weeks: endoscopic or radiologic replacement is the only safe option 1
Position Confirmation Before Use
You must confirm proper intragastric position before administering any feeds, fluids, or medications through the Foley catheter. 1, 3
Use multiple confirmation methods:
- pH testing: Aspirate gastric contents and confirm pH ≤5 1
- Irrigation test: Flush with 3-50 mL sterile water—should flow without resistance or leakage around the stoma 1
- External length assessment: Measure and document the external tube length 1
- Tube manipulation: Rotate and move the tube in-and-out to confirm mobility 1
- Water-soluble contrast study: Mandatory if there was ANY difficulty during insertion or if blind replacement was performed 1, 3
Critical Safety Measures
Secure the Foley Catheter
- Affix the catheter to the skin immediately to prevent antegrade migration into the small bowel 4, 2
- Migration can cause small bowel obstruction requiring colonoscopic or surgical removal 4, 2
- Four patients in one series developed small bowel obstruction from migrated Foley catheters 2
Monitor for Complications
Foley catheters have a 42.6% complication rate when used as gastrostomy tubes: 2
- Balloon rupture with peristomal leakage (most common) 2
- Lumen blockage from feeding formula 2
- Antegrade migration causing bowel obstruction 4, 2
- Intraperitoneal placement causing peritonitis (can be fatal) 5
Replace with Proper Gastrostomy Tube Promptly
- Foley catheters are designed for urinary drainage, not enteral feeding 1, 2
- The universal safety connectors (ENFit®) make feeding through Foley catheters more difficult 1
- While some patients have safely used Foley catheters for up to 18 months, this is NOT recommended practice 2
- Plan replacement within days, not weeks 1, 2
Common Pitfalls to Avoid
Do not assume the tract remains patent for more than a few hours—tracts can close rapidly, especially in the first 24 hours after dislodgement 1
Do not skip position confirmation—intraperitoneal placement of replacement tubes has caused peritonitis and death in patients with mature tracts 5
Do not use excessive force during insertion—if there is ANY resistance, stop and obtain endoscopic or radiologic guidance 1, 3
Do not forget to check balloon volume weekly—Foley balloons degrade and deflate, leading to dislodgement 1, 2
Do not leave the Foley catheter in place long-term—arrange for proper gastrostomy tube replacement as soon as logistically possible 1, 2
Special Considerations for Delayed Wound Healing
Patients with the following conditions may have immature tracts even beyond 4 weeks: 1
- Malnutrition
- Ascites
- Corticosteroid therapy
- Diabetes with poor glycemic control
- Immunosuppression
In these patients, consider endoscopic or radiologic replacement even if >4 weeks post-placement. 1
