RESUMEN
Percutaneous endoscopic gastrostomy (PEG) is used for nutritional support to the patients who cannot maintain the adequate oral intake. Compared with operative gastrostomy, PEG is a safe, rapid, and less expensive technique. Among several complications, buried bumper syndrome is a late complication in which internal bumper erodes into the gastric wall or migrates into the abdominal wall due to improper compression to the gastric wall. We here report a patient with peritubular leakage, resistance of tube feeding, and abdominal pain which were developed 13 months after percutaneous endoscopic gastrostomy. On endoscopic examination, the gastrostomy lumen could not be found. The gastrostomy tube was replaced successfully to new one with single procedure endoscopic technique. No complication was occurred and the function of tube has been well preserved.
