A knotty problem: phytobezoar and small bowel occlusion as a complication of a gastro-jejunal catheter for continuous Duodopa infusion: a case report

We report a case of small bowel occlusion due to the formation of a bezoar around a knot at the distal end a gastro-jejunal catheter used for continuous levodopa/carbidopa intestinal gel (LCIG) in a patient with advanced Parkinson’s disease. The patient presented with a history of abdominal pain and vomiting starting 24 h before admission and frequent failure of his LCIG device for the past week. Small bowel occlusion along with a knot formation on the distal catheter was confirmed by contrast enhanced CT scan. After failure of endoscopic extraction, the patient was taken to theater. The presence of a knot and a bezoar was confirmed and extraction proceeded via transverse enterotomy without the need for bowel resection. Despite inhalation pneumonia and prolonged ileus, the patient recovered fully. LCIG treatment was reinstated a month later through new gastro-jejunal catheter. This case highlights a severe and surprising complication of LCIG treatment.
