Comparison of the CE findings between the CKD and non-CKD patients.
| CKD patients (N = 42) |
Non-CKD patients (N = 132) |
P value | |
|---|---|---|---|
| Abnormal CE findings (highly relevant lesions) | 26 (62.0) | 58 (43.9) | 0.04 |
| Vascular lesions | 20 (47.6) | 27 (20.5) | <0.001 |
| Angioectasia | 16 (38.1) | 26 (19.7) | 0.02 |
| Arteriovenous malformations | 1 (2.4) | 0 (0) | — |
| Varices | 1 (2.4) | 0 (0) | — |
| Active bleeding with no identifiable cause | 2 (4.8) | 1 (0.8) | 0.08 |
| Erosive/ulcerated lesions | 14 (33.3) | 36 (27.3) | 0.45 |
| Ulcerations | 7 (16.7) | 20 (15.2) | 0.59 |
| Erosions (≥3) | 7 (16.7) | 16 (12.1) | 0.39 |
| Diverticula | 0 (0) | 1 (0.8) | — |
| No findings (less relevant lesions or no abnormalities) | 16 (38.1) | 74 (56.1) | — |
Small bowel lesions that were considered to be the cause of the OGIB, such as angioectasia, dieulafoy's lesions, varices, arteriovenous malformations, ulcerations, multiple (≥3) erosions, diverticula, or the presence of blood and/or blood clots in the lumen of the small bowel, were considered as highly relevant lesions.
P values were calculated using the chi-squared test.
