| Ding et al. | 2019 | 4,206 abnormalities in 3,280 patients | To analyze SB-CE images with greater accuracy and sensitivity than conventional methods | 99.88% sensitivity in the per-patient analysis (95% confidence interval [CI], 99.67–99.96) | Aoki et al. | 2019 | 113,426,569 images from 6,970 patients | To develop a CNN-based algorithm that could automatically detect erosions and ulcers from capsule endoscopic images | With 99.88% sensitivity in the per-patient analysis (95% CI, 99.67–99.96) and 99.90% sensitivity in the per-lesion analysis (95% CI, 99.74–99.97) | Klang et al. | 2019 | 17,640 CE images from 49 patients | To evaluate a deep learning algorithm for the automated detection of small-bowel ulcers in Crohn’s disease (CD) on capsule endoscopy (CE) images | AUCs (area under the curve of 0.99 and accuracies ranging from 95.4–96.7% | Klang et al. | 2021 | 27,892 CE images | To prove the ability of deep neural networks to identify intestinal strictures on CE images of Crohn’s disease (CD) patients | A differentiation between strictures and normal mucosa (area under the curve [AUC], 0.989) | Barash et al. | 2021 | 17,640 CE images from 49 patients | To develop a deep learning algorithm for automated grading of CD ulcers on CE | The accuracy of the algorithm was 0.91 (95% CI) for distinction of 3 different grades |
