Background/AimsMotility disorders are prevalent, often leading to disrupted regional or whole gut transit times. In this study, we conducted a comparative analysis between the wireless motility capsule and an innovative gas-sensing capsule to evaluate regional and whole gut transit times in individuals with diagnosed motility disorders. MethodsWe prospectively enrolled 48 patients (34 women) diagnosed with functional dyspepsia and/or functional constipation according to Rome IV criteria. Patients ingested the capsules in tandem. We assessed the agreement between transit times recorded by both devices using Spearman correlation and Bland-Altman analysis. Additionally, diagnostic concordance between the capsules were evaluated using confusion matrices. ResultsWe observed a significant correlation between the wireless motility capsule and the gas-sensing capsule for gastric emptying time (r = 0.79, P < 0.001) and colonic transit time (r = 0.66, P < 0.001). The gas-sensing capsule exhibited a sensitivity of 0.83, specificity of 0.96, and accuracy of 0.94 when using the standard cutoff for delayed gastric emptying (5 hours). Similarly, when applying the cutoff value for delayed colonic transit (> 59 hours), the gas-sensing capsule demonstrated a sensitivity of 0.79, specificity of 0.84, and accuracy of 0.82. Importantly, the gas-sensing capsule was well-tolerated, and no serious adverse events were reported during the study. ConclusionsOur findings underscore the gas-sensing capsule’s suitability as a dependable tool for assessing regional and whole gut transit times. It represents a promising alternative to the wireless motility capsule for evaluating patients with suspected motility disorders.
