Direct intrajejunal levodopa-carbidopa intestinal gel (LCIG) administered through a percutaneous endoscopic gastrostomy (PEG) with a jejunal extension tube (PEG-J) is an FDA-approved modality for treatment of patients with advanced Parkinson's disease (PD). Buried bumper syndrome (BBS) is a rare complication associated with PEG tubes inserted for drug administration or enteral feeding. The syndrome is diagnosed endoscopically revealing burial of the internal bumper in the gastric wall, causing numerous serious complications. When only the J extension of a PEG-J is used to deliver medications, and the G tube is not utilized, a delay in the diagnosis of BBS can occur. This is likely as the small caliber J extension tube remains patent and functional. We present the case of an elderly patient with advanced PD on LCIG therapy, who presented with a dislodged J-tube from a PEG-J system. Endoscopy revealed BBS that had likely developed prior to dislodgment of J-extension and despite a conservative approach, the internal bumper needed to be surgically extracted to prevent further complications.
