Effect of Povidone-iodine Washing of Gastrointestinal Mucosa or Taking Proton Pump Inhibitors on Bacteremia after Endoscopic Ultrasonography-guidedine Needle Aspiration

We report a case of cardiac rhabdomyosarcoma, with initial clinical features of "atrial rhythmic dysfunction, " which wasconcluded as a mediastinal tumor by computed tomography (CT) scan. Endoscopic ultrasonography (EUS) and EUS-FNA (fineneedle aspiration) were initially conducted to diagnose the isolated mediastinal mass. In this case, EUS re-assessed the previousdiagnosis as a cardiac tumor, and the patient eventually achieved a 17-month survival rate after chemotherapy. In this paper,EUS findings obtained in our case are described and a review of literatures is briefly discussed. We also describe the advantagesand limitations of this technique compared with other image diagnosis alternatives.
