Management of Gastrostomy Tube Leakage

Assessment of Underlying Causes

Excessive tube mobility, incorrect tube sizing, and infection are the most common reasons for leakage; barrier protection should be applied and, if conservative measures fail, the tube may be removed for 24–48 hours to allow tract closure. 1
The external bolster should allow approximately 0.5–1 cm of play between the tube and the skin; tighter or looser tension increases leakage risk. 2
Balloon‑type tubes degrade over time and typically require replacement every 3–4 months to maintain integrity. 3
An enlarged stoma tract that no longer fits the tube properly contributes to leakage. 3
Signs of peristomal infection include erythema, purulent or malodorous exudate, loss of skin integrity, fever, and pain. 4
Granulation tissue—vascular tissue that bleeds easily—often results from excess moisture, friction, or infection. 3

Stabilize the tube with a clamping device to prevent side torsion and maintain proper alignment. 3
Verify the water volume in balloon tubes according to manufacturer specifications to ensure adequate balloon inflation. 3
If excessive movement persists, consider switching to a low‑profile gastrostomy device. 3

Apply stoma adhesive powder or zinc oxide to the peristomal skin to reduce irritation from gastric contents. 5
Use foam dressings rather than gauze; foam lifts drainage away from the skin while gauze traps fluid and promotes maceration. 7
Apply a barrier film or cream to protect surrounding skin from exposure to gastric secretions. 3
Clean the affected skin at least once daily with an antimicrobial cleanser. 1

Obtain bacterial and fungal cultures from the peristomal area before initiating treatment. 4
Apply topical antimicrobial agents (e.g., silver, iodine, or polyhexamethylene biguanide) in foam, hydrocolloid, or alginate dressings beneath the fixation device. 4
Topical antibiotics should not be used for peristomal infection. 4
If infection persists despite topical therapy, add systemic broad‑spectrum antibiotics for 5–7 days (oral for early/mild cases, intravenous for systemic signs). 8
Recognized risk factors for infection include diabetes, obesity, poor nutritional status, chronic corticosteroid use, and immunosuppression. 5

Silver nitrate cauterization can be applied directly to over‑granulation tissue to achieve hemostasis. 3
Topical corticosteroid cream or ointment for 7–10 days, combined with a compressive foam dressing, reduces granulation tissue formation. 3
Antimicrobial foam or silver‑impregnated dressings should be changed weekly or when significant exudate is present. 3
For refractory granulation, surgical excision or argon plasma coagulation may be considered. 3

Upsizing the gastrostomy tube is ineffective and typically worsens leakage by enlarging the stoma. 5
Removing the tube for 24–48 hours allows partial spontaneous tract closure; a suitably sized tube can then be re‑inserted. 1
Conversion to a gastrojejunostomy should be considered when gastric drainage remains problematic. 5
If all other measures fail, a new gastrostomy can be placed at a different abdominal location. 1

Wound and ostomy nurses serve as primary managers for leaking gastrostomy sites and are valuable resources for care coordination. 5
Local fungal skin infections may accompany leakage; treat these with topical antifungal agents. 7
Indications for complete tube removal include:

Excessive external bolster tension can cause pressure necrosis, infection, increased leakage, and buried bumper syndrome. 5
Using gauze dressings instead of foam traps gastric contents against the skin, leading to maceration. 5
Upsizing the tube creates a larger stoma and aggravates leakage. 5
Occlusive dressings maintain a moist environment that promotes skin maceration. 2
Application of topical antibiotics to the peristomal area should be avoided. 4
