Wireless capsule endoscopy: concept and modalities

The introduction of capsule endoscopy (CE) for the study of the small bowel represented a ground-breaking innovation in the field of gastrointestinal endoscopy at the dawn of the new millennium. Several new devices have been developed throughout the years, expanding the scope for other digestive segments and fulfilling the needs of clinicians for new indications. As of today, artificial intelligence represents the main exploration area in CE: With the aim of overcoming the intrinsic limitation of the human factor, the development and application of these technologies are about to mark the beginning of a new golden age for CE.
