Percutaneous endoscopic gastrostomy (PEG) is used for nutritional support in patients who require prolonged tube feeding. However, numerous complications have been reported since its introduction. Buried bumper syndrome is an uncommon, but well-documented, complication of PEG placement. The condition often results from excessive pressure exerted on the gastric mucosa by the tight anchorage between the internal and external bumpers. This leads to mucosal erosion and embedding of the internal bumper in the gastric wall, which obstructs feeding. We report two cases of buried bumper syndrome: one was corrected using the push technique and the other was removed surgically.
