Percutaneous endoscopic gastrostomy is used for long-term nutritional support to the patients who cannot maintain the adequate oral intake and can be performed with relatively few complications. Among the complications, migration of the internal bumper into the abdominal wall, so called "buried bumper syndrome" has been described more recently. We decribed a case of buried bumper syndrome in stroke patient with percutaneous endoscopic gastrostomy. He experienced peritubular leakage, resistance of tubal feeding, and abdominal pain which were developed 4 weeks after percutaneous endoscopic gastrostomy. On endoscopic examination, the gastrostomy lumen coud not be found. The gastrostomy tube was replaced with careful manual traction and replaced to new one with endoscopic technique. No complication was occurred and the function of tube has been well preserved.
