In patients with a functional gastrointestinal (GI) tract, enteral feeding is preferred over parenteral feeding as it has fewer complications and a relatively lower cost. Nasogastric and nasoenteric feeding tubes are available options but when long-term enteral feeding is desired, a percutaneous endoscopic gastrostomy (PEG) tube is more convenient. PEG tube can be associated with multiple complications; however, its displacement which causes gastric outlet obstruction (GOO) is a rare one. Here we present a case of an 81-year-old woman with dementia who presented with upper GI bleeding and was found to have GOO causing reflux esophagitis due to PEG tube displacement.
