Special Issue Introduction

Capsule endoscopy, since its introduction in 2000, has revolutionized the field of gastrointestinal (GI)
diagnostics, offering a non-invasive, patient-friendly alternative to traditional endoscopic procedures.
Initially designed for small bowel examination, capsule endoscopy has rapidly evolved, extending its
applications to visualize the esophagus, stomach, and even the colon. With advancements in imaging
technology, magnetic navigation, and artificial intelligence (AI)-driven analysis, capsule endoscopy is
redefining the possibilities for early diagnosis, disease monitoring, and therapeutic interventions in GI
medicine.

Over the past two decades, capsule endoscopy has achieved remarkable progress in terms of image
resolution, battery life, and data transmission capabilities. Enhanced endoscopic imaging, including dual-
camera capsules and 360-degree panoramic views, now allows for high-definition visualization of mucosal
surfaces, enabling more accurate detection of lesions, bleeding sources, and inflammatory conditions.
Additionally, AI integration has paved the way for automated image interpretation, significantly improving
diagnostic accuracy and reducing physician workload.

This Special Issue explores the current development status of capsule endoscopy, including innovations
in hardware (e.g., multicamera capsules, controllable locomotion) and software (e.g., machine learning for
lesion detection). It also highlights future expectations, such as the integration of robotic features, targeted
drug delivery, and enhanced diagnostic accuracy through AI. Contributions from leading researchers and
clinicians provide insights into the challenges and opportunities shaping the next generation of capsule
endoscopy.

By addressing both technological progress and clinical applications, this issue aims to foster discussion on
how capsule endoscopy can further transform gastroenterology and improve patient outcomes.
