Unusual Complication of Percutaneous Gastrostomy Tube Replacement.

Percutaneous endoscopic gastrostomy tubes are commonly used for long-term nutritional support in patients with impaired swallowing due to neurological conditions, malignancy, or critical illness. Although placement, removal, and replacement are generally safe, complications may occur. We report a case of complete gastric outlet obstruction due to unusually deep percutaneous endoscopic gastrostomy tube insertion during replacement in a 63-year-old man with esophageal cancer. Symptoms resolved after repositioning the tube. This case highlights the need for proper training and postreplacement verification to ensure safe outcomes.
