Aspiration of an M2A Capsule

Abstract

A 64-year-old patient was referred to our hospital for further evaluation of anemia. Due to recent mechanical mitral valve replacement, the patient was receiving phenprocoumon for effective anticoagulation. He presented in a markedly impaired clinical condition (174 cm, 47 kg). Since previous upper gastrointestinal endoscopy and colonoscopy had not revealed any bleeding source, wireless small bowel capsule endoscopy was performed.
