Life-Threatening Gastrointestinal Bleeding due to a Jejunal Lesion of Henoch-Schönlein Purpura

The case of a 56-year-old patient with Henoch-Schonlein purpura (HSP) and fulminant gastrointestinal bleeding is reported. The patient was admitted to hospital because of palpable purpura on both legs, painful joints and diffuse abdominal pain. Suspected HSP was histologically proven and treated with prednisolone. Despite recovery, acute gastrointestinal bleeding, with melena and a drop in hemoglobin concentration from 11.2 to 4.2 g/dl, occurred 30 days after medication was started. Immediate endoscopic examination of the upper gastrointestinal tract showed no signs of bleeding whereas colonoscopy showed fresh blood and blood clots in the terminal ileum and the colon. Since the bleeding source could not be detected endoscopically, mesenteric angiography was performed, demonstrating active bleeding from a jejunal artery. Thereafter the bleeding source was located by intraoperative peroral enteroscopy and treated by resection of a short segment of jejunum.
