Buried bumper syndrome: cut and leave it alone!

Abstract

Buried bumper syndrome (BBS) occurs due to the overgrowth of gastric mucosa over the inner bumper of a gastrostomy tube. Various therapeutic approaches have been described for the management of BBS. However, no standardized clinical protocol deals with this complication. The authors describe their experience of dealing with BBS. Case notes of the patients undergoing percutaneous endoscopic gastrostomy (PEG) between February 2002 and December 2007 at their institute were reviewed retrospectively, and cases of BBS were analyzed. During this 71-month period, 356 PEG procedures were preformed. Seven patients with BBS were identified from the case note review (incidence of 1.97%). Attempts at endoscopic removal of the buried bumper were made but unfortunately failed. In view of the patients' associated comorbidity, the buried bumpers in these patients were left in situ, and a new PEG was inserted adjacent to the first site in 6 individuals. In 1 patient, a jejunal extension tube was inserted through the original PEG tube for feeding. No complications from the buried bumper arose in these patients during a median follow-up of 18 months (range, 1-46 months). Some patients being fed by a PEG tube are in poor general health and have significant comorbidities. They are therefore poor candidates for surgical or endoscopic removal of a buried bumper. In such patients, leaving the internal bumper in situ should be considered as a relatively safe treatment option.
