Concordance between capsule endoscopy and device-assisted enteroscopy in small-bowel lesions

Area of Science:

• Gastroenterology
• Endoscopy
• Small Bowel Imaging

Background:

• Small-bowel (SB) tumors present diagnostic challenges.
• Capsule endoscopy (CE) and device-assisted enteroscopy (DAE) are key diagnostic tools for the SB.
• Comparing the diagnostic agreement between CE and DAE is crucial for clinical practice.

Purpose of the Study:

• To evaluate the agreement between capsule endoscopy (CE) and device-assisted enteroscopy (DAE) in diagnosing small-bowel (SB) lesions.
• To compare the agreement for different types of SB lesions, including tumors, ulcers, and angioectasias.

Main Methods:

• Review of a clinical case involving CE and DAE.
• Analysis of diagnostic concordance between CE and DAE findings.
• Case presentation of ileum carcinoid tumors identified by CE and managed with DAE.

Main Results:

• High agreement observed between CE and DAE for small-bowel tumors.
• Greater agreement between CE and DAE for non-tumorous lesions like ulcers and angioectasias.
• Successful identification, biopsy, and tattooing of ileum carcinoid tumors using CE and DAE.

Conclusions:

• CE and DAE demonstrate significant agreement in diagnosing small-bowel tumors.
• The concordance between CE and DAE is notably higher for ulcers and angioectasias compared to tumors or polyps.
• Combined use of CE and DAE facilitates accurate diagnosis and targeted intervention for SB lesions.
