The Future of Magnetic Guided Capsule Endoscopy: Designed for Gastroscopy, Does It Have a Role in Small Bowel Enteroscopy?

In this chapter, we summarize the large clinical trials on magnetically guided capsule endoscopy. We initially describe this innovative technology. Paul Swain was a pioneer in capsule development, but he used a rather primitive guided system. Based upon this, Olympus Medical System and Siemens Healthcare developed a sophisticated capsule guidance mechanism. Early clinical results were encouraging and more useful than expected. But a large, blinded and randomized trial shows current limitations of guided capsule endoscopy compared to the gold standard: high definition gastroscopy.

• Keio University School of Medicine, Tokyo, Japan: Haruiko Ogata, Naoki Hosoe, Toshifumi Hibi.
• Showa University Northern Yokohama Hospital, Yokohama, Japan: Kazuo Ohtsuka, Noriyuki Ogata, Shin-El Kudo.
• Jikei University School of Medicine, Tokyo, Japan: Keiichi Ikeda, Hiroyuki Aihara, Hisao Tajiri.
• Department of Interdisciplinary Endoscopy, University Hospital Hamburg-Eppendorf, Hamburg, Germany: Ulrike Denzer, Thomas Rösch, Andras Treszl, Karl Wegscheider.
• Department of Gastroenterology, Centre Hospitalier Universitaire and University of Nice Sophia Antipolis, Nice, France: Xavier Hebuterne, Geoffroy Vanbiervielt, Jerome Filippi.
Technical Acknowledgements: These trials have been supported by excellent technical teams from Olympus endocapsule system and Siemens Healthcare, and by all the nursing team of Institut Arnault Tzanck.
We are grateful to our Japanese colleagues who accepted to spend time in St. Laurent Du Var for the achievement of the trial.
