Capsule endoscopy uses swallowable pill cameras to visualize the gut without the need for intubation with flexible endoscopes or radiation exposure. Images transmitted to a data recorder are converted to a video format and viewed remotely on a computer screen. In the decade since the first description of this technology, capsule endoscopy has become a first line small bowel investigative modality; early data suggest that a second-generation colon capsule approaches the diagnostic sensitivity of conventional colonoscopy, and whilst the oesophageal capsule has not established a large market, the ability to image the foregut as well as the mid- and hindgut raises the future prospect of remote whole gut visualization. The respective diagnostic roles of capsule endoscopy, conventional endoscopy, and radiological imaging will depend on accuracy, safety, patient preference, complexity of the test, and cost.

The focus of this special issue will be on capsule endoscopy in clinical practice. Any form of original research (including meta-analyses) which studies aspects of oesophageal, small bowel, or colon capsule endoscopy will be considered. Manuscripts addressing all aspects of clinical practice are encouraged, including indications for capsule endoscopy, safety, and quality of procedures, technical developments, effect on outcomes, and training of capsule endoscopists. Potential topics include, but are not limited to:

• Diagnostic utility of capsule endoscopy
• The role of capsule endoscopy alongside other imaging modalities
• Bowel preparation prior to capsule endoscopy
• Patient tolerance of capsule endoscopy
• Avoidance of complications of capsule endoscopy
• The effect of capsule endoscopy on management and patient outcomes
• Capsule endoscopy in screening, surveillance, or assessment of treatment response of gastrointestinal disease
• Training in capsule endoscopy
• Technological developments in capsule endoscopy
