Challenges and future of wireless capsule endoscopy

Abstract

In 2015, capsule endoscopy was introduced as the main investigation method for small bowel mucosal diseases, and its role in colonic diseases has been gradually revealed. Future challenges for capsule endoscopy, besides improvements of image quality and visualization of each part of the small bowel and colonic mucosa, include the development of gastric capsules, the capacity to perform histological examination of the mucosa, and maybe in the future, some capsule endoscopy-driven therapeutics. The aim of this review was to evaluate the clinical demands and feasibility of achieving the aforementioned objectives.
