Duodenal infusion allows a steady absorption of the drug in the small bowel, reducing plasmatic fluctuations of levodopa. Some complications may occur during the treatment, often related to intrajejunal percutaneous endoscopic gastrostomy (PEG-J). We report a case of duodenal ulcer associated with a phytobezoar involving the end of jejunal probe, in a patient who underwent PEG-J for LCIG infusion. In the last 2\u2009weeks, the patient suffered from abdominal pain and dyspepsia. Oesophagogastroduodenoscopy showed an ulcerative lesion of the duodenum due to traction of the jejunal tube; the end of the jejunal tube was wrapped in a phytobezoar. This case is interesting because of the extension of the ulcerative lesion due to PEG-J dislocation and because of the subtle symptoms associated with it.<\/jats:p>","DOI":"10.1136\/bcr-2017-223884","type":"journal-article","created":{"date-parts":[[2018,6,30]],"date-time":"2018-06-30T02:25:24Z","timestamp":1530325524000},"page":"bcr-2017-223884","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Phytobezoar
