Capsule endoscopy requires patients to ingest a vitamin sized pill containing a camera that provides images of the gastrointestinal mucosa
Capsule endoscopy is complementary to double balloon endoscopy for detecting obscure gastrointestinal bleeding and small intestinal tumours
Oesophageal capsule endoscopy is a safe alternative to upper gastrointestinal endoscopy in the surveillance of patients with Barrett’s oesophagus, although cost may limit its use
Colonic capsule endoscopy may be useful in the detection of colorectal cancer when colonoscopy is incomplete or contraindicated
Magnetically guided capsules may be useful in cystoscopy and as the imaging platform for natural orifice transluminal endoscopic surgery
Technological challenges for the next generation of devices include reducing component size, improving power management, and introducing capsule locomotion
Capsule endoscopy was unveiled at Digestive Disease Week 2000 in San Diego, California, USA, by Paul Swain, gastroenterologist at Imperial College St Mary’s Hospital, London, and Given Imaging, a Yoqneam (Israel) company, as the product of collaborative research and development activities between the two groups.1 The past few years have seen advances in this technology, which is now part of established clinical practice in North America, Europe, the Far East, and Australia, particularly for imaging the small bowel. This article describes current clinical applications of capsule endoscopy and looks at future developments.

What is capsule endoscopy?
Capsule endoscopy is performed by ingestion of a small (26×11 mm) disposable battery powered pill containing a complementary metal oxide semiconductor camera (fig 1⇓), which provides …
