Buried bumper syndrome in percutaneous endoscopic gastrostomy with a jejunal extension tube in patients undergoing levodopa–carbidopa intestinal gel treatment

Abstract

Abstract Background Levodopa–carbidopa intestinal gel (LCIG) treatment is an effective Parkinson’s disease (PD) treatment that requires percutaneous endoscopic gastrostomy with a jejunal extension tube (PEG-J). Buried bumper syndrome (BBS) is an uncommon but significant complication of PEG-J for LCIG. Case presentation A 71-year-old man had been undergoing LCIG therapy for PD since a PEG-J was implemented at our department two years previously. He presented with appetite loss. Computed tomography showed that the gastrostomy bumper was buried in the gastric wall. The patient was surgically treated with the simultaneous removal and replacement of PEG-J. Postoperative gastrocutaneous fistula occurred, which was conservatively treated. Conclusions Notably, patients and medical staff should be aware that patients with PD on LCIG treatment have a high risk of BBS in PEG-J and that there might be some patients with latent BBS. When simultaneous removal and replacement surgery is performed, establishing a new route at the stomach and abdominal wall is recommended.
