Background and study aims Despite the common occurrence of non-neoplastic findings (NNFs) in individuals with a positive fecal immunochemical test (FIT), few studies have reported on these findings. The aim of this cross-sectional study was to determine the prevalence of colonic NNFs in three cohorts of Danish clinical trial participants who underwent colon capsule endoscopy (CCE). Patients and methods Retrospectively collecting NNFs from CCE reports of three Danish trials, we classified them into five categories: diverticula, vascular abnormalities, inflammation, erosions/ulcerations, and others. The statistical analysis included 516 participants from three trials, with a mean age ranging from 59.2 to 63.9 years. The participants in the three trials were FIT-positive screening or symptomatic individuals. Results NNFs were reported in more than half of the CCE procedures (50.6% to 77.9%), with colonic diverticula being the most common NNF appearing in 40.9% to 66.9% of the CCE reports. Vascular abnormalities and erosions/ulcerations were also common depending on the specific trial. Conclusions NNFs are common and may be an indicator of more widespread disease. Furthermore, NNFs may develop into clinically significant conditions despite their benign appearance. This paper expands on the limited literature about prevalence of NNFs and underscores the additional value of CCE video recordings beyond detecting polyps.

The gastrointestinal (GI) tract, particularly the small bowel (SB), can be challenging for novel investigation tools

Background/Objectives: Colonoscopy is the standard examination for many symptomatic patients referred for lower-gastrointestinal investigation, but it is resource-intensive and may be a burdensome experience. Colon capsule endoscopy (CCE) offers a minimally invasive, sedation-free first-line examination, although clinically important findings, inadequate cleansing or incomplete transit can generate downstream colonoscopy. DanCap aims to compare the costs and clinical consequences of a CCE-first pathway with routine conventional colonoscopy (CC). Methods: DanCap is a single-centre, cluster-allocated crossover trial at Odense University Hospital, Denmark. General practice clinics follow CCE or CC according to the parity of their pre-existing provider number, with pathways crossing after 200 consecutive CCE participants; no trial-generated random allocation sequence is used. Eight hundred symptomatic adults aged >18 years referred for expedited lower-gastrointestinal investigation are planned. CCE participants with suspected cancer, any polyp ≥6 mm, inadequate cleansing or an incomplete examination are referred for colonoscopy. The primary outcome is pathway cost. Registered secondary outcomes and prespecified process measures include polyp and colorectalcancer detection, examination quality, reinvestigation and patient-reported consequences. FIT and microbiome are registered secondary outcomes; participation in the substudy is optional and the analyses are exploratory within the CCEpathway. Primary analyses will follow the assigned pathway and account for GP clinic clustering, period and allocation sequence. Expected Results: The trial will quantify the resource use and clinical consequences of implementing CCE in routine symptomatic practice. Conclusions: DanCap is intended to inform decisions about CCE pathway implementation rather than to establish unbiased whole-cohort test sensitivity or specificity.
