[Real-time 3D reconstruction CT-jejunography guided direct percutaneous endoscopic jejunostomy for levodopa-carbidopa intestinal gel treatment in a patient with prior gastrojejunostomy].

A 68-year-old woman with Parkinson's disease, who had previously undergone Roux-en-Y gastrojejunostomy for early gastric cancer, complained of wearing-off and troublesome dyskinesia that had progressed over 7-years. After the introduction of levodopa-carbidopa intestinal gel therapy (LCIG) by nasojejunal tube, she had a good clinical response. Percutaneous endoscopic gastrostomy with a jejunal extension tube was difficult in this case, due to lack of gastrostomy site and fibrous postoperative adhesion. We introduced LCIG by direct percutaneous endoscopic jejunostomy (D-PEJ) which offers a less invasive procedure to operative tube placement. The factors affecting the success of D-PEJ could interfere with transillumination, abdominal thickness and the location of other organs. We determined the optimum site of catheter insertion with the assistance of real-time 3D reconstruction CT-jejunography. She was discharged home on postoperative day 14 without any procedure-related complications. Real-time 3D reconstructive CT-jejunography guided D-PEJ is a useful method for a patient who benefit from LCIG with prior gastrojejunostomy.
