feeding tube presented with impairment of flow. Mobilization of the tube proved impossible. Endoscopy confirmed the buried bumper syndrome, with the internal bumper being completely buried. Only the lumen of the internal tube could be suspected. We cut the external end of the tube at 3 cm from the abdominal wall and inserted a guide wire through the lumen into the stomach. An 18 mm esophageal balloon dilator was placed over the guide wire and through the endoscope (TTS) into the gastric tubular lumen of the PEG-tube. The balloon was inflated to the recommended maximum pressure so it remained solidly impacted in the PEG tube. Traction of the endoscope and balloon catheter permitted extraction of the bumper through the stomach and mouth. A new PEG tube was inserted during the same procedure using the guide wire, still in place. So only one endoscopy was needed. The patient’s further course was uneventful.
