Are PEGJs a Risk Factor for the Buried Bumper Syndrome?

Abstract

AimPercutaneous endoscopic gastrostomies (PEGs) with or without a jejunal extension (PEGJs) are a well-accepted method of enteral feeding. They are associated with a number of complications, including the buried bumper syndrome (BBS). We aimed to identify risk factors for BBS, our current management strategies, and optimal timing for surgical treatment. MethodsHospital coding and a database compiled by our specialist nutrition nurse were used to identify all cases of buried bumpers from January 2012 to December 2014 as well as all PEG/PEGJ devices inserted during this time. A retrospective case note review was performed for each patient with BBS to identify risk factors, management strategies, and outcomes. ResultsTwo hundred twelve PEGs and 22 PEGJs were inserted. Nine patients were identified with BBS. Patients with PEGJ tubes were significantly more likely to develop BBS (7/22, 32%) than those with PEG tubes (2/212, 0.9%) P<0.01. There was one death in the study group because of abdominal sepsis associated with an intraperitoneal PEG bumper 33days after BBS was diagnosed and before removal was attempted. All other patients underwent laparotomy to remove the bumper. Mean hospital stay was 22days postoperatively. ConclusionsBuried bumper syndrome is a serious condition which warrants urgent intervention. We have demonstrated a higher than expected rate of BBS associated with PEGJ tubes. We hypothesize that this may be related to the jejunal extensions leading to difficulty in the usual maintenance regimen that all carers are taught after PEG/PEGJ insertion.
