Pressure necrosis is sometimes related to the use of internal and external bumpers or retention devices. Excessive compression between the two bumpers can cause abdominal and/or gastric wall necrosis. Excessive traction can occur not only at the time of placement, but also long term. Pressure necrosis can occur with all types of feeding tubes but is reported in this article with PEG tubes. Progressive migration of the bumper into the gastric wall can result in “buried bumper” and displacement of the tube. Three case studies will illustrate different possible causes for pressure necrosis and “buried bumper.” Strategies for prevention and interventions for existing ulcer will be presented.
