Applicability of colon capsule endoscopy in FIT-positive individuals unable or unwilling to undergo colonoscopy within a colorectal cancer screening programme: a prospective multicentre study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Colorectal cancer (CRC) screening programmes commonly use the Faecal immunochemical test (FIT) followed by colonoscopy. When colonoscopy is not feasible, computed tomography colonography (CTC) serves as an alternative. However, CTC has limitations, such as lower sensitivity for smaller polyps and radiation exposure. Colon capsule endoscopy (CCE) is a non-invasive alternative that may improve polyp detection in FIT-positive individuals. Objectives: To evaluate the feasibility of CCE in FIT-positive participants from the Dutch CRC screening programme who are unable or unwilling to undergo colonoscopy. Design: Prospective multicentre, interventional study. Methods: FIT-positive participants ingested the PillCam Results: Of 169 FIT-positive participants unable to undergo colonoscopy, 54.4% were ineligible for CCE due to contraindications. CCE was performed in 13 participants, with a completion rate of 69.2% and adequate bowel preparation in 38.5. A total of 54 polyps were detected, 46.3% of which were ⩾6 mm. The per-patient detection rate for polyps ⩾6 mm was 76.9%. In 84.6% of cases, follow-up colonoscopy was advised. CCE findings matched colonoscopy in 66.7% of cases; in the remaining 33.3%, polyps were found to be < 6 mm during colonoscopy. One participant was diagnosed with a pT4bN0M0 adenocarcinoma after CCE revealed a tumorous obstruction. Conclusion: Despite a high per-patient PDR, this study indicates that CCE is less suitable for FIT-positive individuals unable or unwilling to undergo colonoscopy due to high comorbidity and frequent contraindications. Inadequate bowel preparation, likely due to reduced gastrointestinal motility, further limited feasibility. Given the elevated risk of advanced neoplasia in this population, many still required follow-up colonoscopy. Therefore, CCE may be better suited for lower-risk populations with fewer procedural limitations. Trial registration: Overview of Medical Research in the Netherlands, NL-OMON55511.
