A 75-year-old man attended our hospital for replacement of a percutaneous endoscopic gastrostomy (PEG) tube. He had originally undergone PEG tube placement at our hospital 2 years ago, and after insertion the position of the hub had been checked by gastroscopy. However, placement of the most recent PEG tube had been done at another hospital 1 year ago, with no gastroscopic evaluation. When the patient attended our hospital 1 year later for replacement of the PEG tube, we could not find its hub in the stomach on gastroscopy. Instead, a scar was detected at the previous gastrostomy site. A nonenhanced abdominal computed tomography (CT) scan taken to check the location of the PEG tube revealed that it had been inserted into the small intestine ([Fig. 1 a, b]).

Gastrografin infusion also showed the hub in the small intestine ([Fig. 2]).

Removal of the malpositioned tube was planned, and we cut the PEG tube at the level of the skin and pushed the remainder of the tube into the lumen, anticipating that the remnant of the PEG tube would be eliminated with stool. After 3 days the hub appeared in the stool.

PEG is a safe and effective procedure, but a variety of complications can occur [1]. Croaker and Najmaldin [2] reported that the PEG tube can pass through the small bowel wall, but it is unlikely that this type of malposition would remain undetected and asymptomatic. Treatment involves removal of the PEG tube and repair of the small bowel. Pearce et al. [3] reported safe removal of the tube in 71/73 patients by the cut and push method, without endoscopic support. We conclude that after PEG tube replacement, gastroscopy should be considered for checking the position of the tube and for any evidence of complications.
