Colon Capsule Endoscopy vs. CT Colonography After Incomplete Colonoscopy
the MPR take:
For patients with incomplete colonoscopy, a colon capsule endoscopy (CCE) may be a superior option to the traditional CT colonography (CTC). 100 patients with a previous incomplete colonoscopy underwent CCE or CTC followed by colonoscopy in case of positive results from either tests. The relative sensitivity of CCE vs. CTC was 2.0 (95% CI 1.34–2.98), pointing to a significant increase in sensitivity for lesions ≥6mm. For larger polyps (≥10 mm), it was 5.1% for CCE and 3.1% for CTC (relative sensitivity: 1.67 (95% CI 0.69–4.00)). Positive predictive values for polyps ≥6mm and ≥10mm were 96% and 85.7% and 83.3% and 100% for CCE and CTC, respectively. While both had comparable efficacy in colon evaluation after incomplete colonoscopy, the CCE overall diagnostic yield was superior to CTC.
Aim of this study was to compare colon capsule endoscopy (CCE) and CT colonography (CTC) in a prospective cohort of patients with incomplete colonoscopy.Design Consecutive patients with a previous incomplete colonoscopy underwent CCE and CTC followed by colonoscopy in case of positive findings on either test (polyps/mass lesions 6mm).
