[A 76-year-old male patient with iron deficiency anaemia - first experience with single-balloon enteroscopy].

Diagnosis of and therapy for small bowl disease is a new challenge for modern endoscopy. Following the development of capsule endoscopy it is possible to inspect the whole small intestine. Therefore one needs adequate endoscopes in order to take tissue samples and perform the corresponding therapeutic measures. Today, the technical procedure of double-ballon enteroscopy is established and is available for routine clinical use. Double-ballon enteroscopy is usable both perorally and peranally, and can be used to inspect the entire small intestine. However, there are a few difficulties with the handling, which are time-consuming. Recently, the new single-ballon enteroscopy system SIF-Q180 was introduced which consists of a dedicated endoscope without an attached balloon, an overtube with a balloon, and an air controller to inflate or deflate the balloon of the overtube. We report the case of a patient admitted to our hospital in order to to detect the reason for an iron deficiency anaemia.
