INTRODUCTION: The pull-PEG (percutaneous endoscopic gastrostomy) is the most commonly used procedure for PEG placement. Alternative methods may be used in patients with an obstructed oesophagus. We here present the case of an unusual complication during PEG placement with the new introducer technique and gastropexy. CASE REPORT: A 74-year-old men with progressive thymus cell carcinoma was referred for a PEG procedure. Since the tumour stenosis in the oesophagus was only passable with a slim-sight endoscope (5,9 mm), we decided in favour of the direct PEG method with gastropexy. The procedure was performed without any complications. 35 days later we changed the balloon catheter and were able to easily inflate the balloon. Surprisingly, the X-ray performed thereafter, revealed a misplacement of the catheter in the colon without any notable contrast medium in the stomach. Although the patient expressed no complaints, he underwent surgery on the same day proving the colocutaneous fistula. There were no signs of peritonitis. The patient's postoperative recovery was uneventful. DISCUSSION: Pull-PEG requires an intact oesophageal passage. The spread of bacteria and tumour cells is a possible risk factor. Direct punction PEG might be better in these cases. This method is not a standard procedure, but the recent implementation of an additional gastropexy represents a significant improvement. We experienced a rare complication, which was first described in 1987. However, this case is the first documented complication in association with gastropexy. This case shows that even gastropexy does not prevent colon interposition. Therefore, an endoscopic or radiological control of the tube placement after changing seems to be necessary.
