Capsule endoscopy: Do we still need it after 24 years of clinical use? (Baishideng Publishing Group)

Capsule endoscopy (CE), introduced in 2000 and FDA-approved in 2001, remains a valuable tool for diagnosing gastrointestinal (GI) lesions, particularly in areas inaccessible to traditional endoscopy. While CE offers non-invasive imaging and improves detection of small bowel diseases and obscure GI bleeding, its widespread use is hindered by limitations such as lack of therapeutic capabilities, inability to obtain biopsies, reliance on peristalsis for movement, and time-consuming image interpretation.
