Capsule Endoscopy in Inflammatory Bowel Disease: When? To Whom?

Area of Science:

• Gastroenterology
• Medical Imaging
• Diagnostic Endoscopy

Background:

• Capsule endoscopy (CE) has been a key diagnostic tool for small bowel diseases for two decades.
• It is utilized for diagnosing Crohn's disease (CD), assessing disease activity, guiding treatment, and monitoring postoperative recurrence.

Purpose of the Study:

• To review the diagnostic utility and evolving applications of capsule endoscopy in gastrointestinal diseases.
• To highlight recent advancements in colon capsule endoscopy (CCE) for ulcerative colitis (UC) and pan-enteric CD.

Main Methods:

• Review of existing literature and clinical applications of capsule endoscopy (CE) and colon capsule endoscopy (CCE).
• Discussion of diagnostic yield, accuracy considerations, and cost-effectiveness of CE.
• Evaluation of new developments and potential uses of CCE in specific patient populations.

Main Results:

• CE demonstrates high diagnostic yield for small bowel lesions, though accuracy requires careful interpretation.
• Cost-effectiveness is a factor, with CE typically used after other diagnostic modalities.
• Colon capsule endoscopy (CCE) shows promise for UC and pan-enteric CD, despite limitations like potential over/underestimation of disease and inability to assess dysplasia.

Conclusions:

• Capsule endoscopy remains crucial for small bowel CD diagnosis and management.
• Colon capsule endoscopy offers a convenient alternative for UC patients, potentially reducing risks associated with colonoscopy.
• Further research may solidify CCE's role in managing UC and extensive CD.
