Unnecessary delay of diagnosis of buried bumper syndrome resulting in surgery.

Percutaneous endoscopic catheter gastrostomy (PEG) is a convenient way to supply enteral nutrition for patients with swallowing disorders. One rare complication of PEG is the buried bumper syndrome where gastric mucosa overgrows the internal bumper and prevents free flow of the feeding solution. As a consequence, the application of enteral feeding has to be stopped until a free outflow is re-established. We report a case of buried bumper where symptoms were misinterpreted for several months as PEG stoma infection by the homecare service. This led to a vastly delayed diagnosis and treatment. As endoscopic intervention was unsuccessful, surgical PEG removal was required. In consequence, we recommend early endoscopic exploration in cases with prolonged inflammatory signs at the PEG stoma site in order to avoid misdiagnosis of buried bumper syndrome and to allow timely endoscopic intervention.
