Chromoendoscopic findings useful for diagnosis and assessment of treatments for ileac lesions of Henoch–Schönlein purpura

Henoch–Schönlein purpura (HSP) is a systemic disease characterized by the deposition of immune complexes and involving multiple organs [1]. One of the organs commonly affected is the gastrointestinal tract. Since approximately 15 % of patients with HSP develop purpura after the appearance of digestive symptoms [2], early diagnosis by detection of gastrointestinal lesions using endoscopy and immediate treatment are necessary. Here, we report two cases of HSP examined by chromoendoscopy with indigo carmine contrast. This procedure clearly delineates the endoscopic features of active ileac lesions of HSP, and has also been proven as useful for treatment assessment.
