Insights
Capsule endoscopy (CE) offers a non-invasive method for diagnosing and monitoring Crohn's disease (CD). This wireless tool aids in assessing disease activity, predicting flares, and guiding treatment decisions for better patient outcomes.
Area of Science:
- Gastroenterology
- Medical Imaging
- Inflammatory Bowel Disease Research
Background:
- Crohn's disease (CD) presents diagnostic and management challenges due to variable clinical features and lack of definitive markers.
- Current management trends in inflammatory bowel disease (IBD) emphasize a treat-to-target approach.
- Assessing disease extent and activity in CD is complex, impacting treatment efficacy.
Purpose of the Study:
- To review the evolving role of capsule endoscopy (CE) in the diagnosis and management of Crohn's disease.
- To highlight CE's utility as a non-invasive tool for monitoring disease activity and mucosal healing.
- To discuss the diagnostic, prognostic, and therapeutic implications of CE in CD patient care.
Main Methods:
- Review of current literature on capsule endoscopy applications in Crohn's disease.
- Analysis of CE's role in initial diagnosis, IBD unclassified (IBDU) cases, and established CD monitoring.
- Evaluation of CE-based disease activity assessment tools, such as the Lewis score.
Main Results:
- Capsule endoscopy provides direct visualization of the small bowel, aiding CD diagnosis and monitoring.
- CE findings influence treatment strategies, including escalation, adjustment, and surgical intervention decisions.
- The Lewis score derived from CE can predict disease flares, offering prognostic value.
Conclusions:
- Capsule endoscopy is an essential, non-invasive tool for comprehensive Crohn's disease management.
- CE facilitates early diagnosis, effective monitoring of mucosal healing, and personalized treatment adjustments.
- The diagnostic and prognostic capabilities of CE optimize patient care across all stages of CD.
Abstract:
Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract, characterized by heterogeneous manifestations with significant morbidities. Diagnosing and managing CD remains challenging due to its variable clinical presentation, complexities in assessing disease extent and activity, and lack of a definitive diagnostic marker. Over the last years, there has been a switch towards a treat-to-target approach in the management of inflammatory bowel disease (IBD). Capsule endoscopy (CE) has emerged as a non-invasive, complementary tool for CD diagnosis and monitoring. CE is patient friendly being wireless and enables direct visualization of the entire small bowel in one sitting. CE plays a role in the diagnostic workup of suspected CD and in cases of in IBD unclassified (IBDU). In established CD, CE plays a role in monitoring mucosal healing, a key therapeutic target linked to improved long-term outcomes. CE findings significantly influence treatment strategies, leading to therapy escalation, adjustment, or avoidance of unnecessary surgical interventions. Moreover, CE disease activity assessment by means of the Lewis score is able to predict disease flares, thus having also a prognostic role. In conclusion, the non-invasive nature of CE, combined with its diagnostic, prognostic, and therapeutic implications, establishes it as an essential tool in the comprehensive management of CD across all disease stages. This review provides a comprehensive update on CE's evolving role in optimizing care of patients with CD.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
