| Scientific title | Comparison of standard versus high definition colonoscopy for polyp detection: a randomised controlled trial |
| Study objectives | We sought to compare the performance of colonoscopy using a high definition (HD), wide-angle endoscope versus a standard colonoscope (SC) for the detection of polyps. |
| Ethics approval(s) | Ethics Committee of the Benizelion General Hospital approved in July 2009 |
| Health condition(s) or problem(s) studied | Colorectal polyps, colonoscopy |
| Intervention | In the SC group, a standard-resolution, standard-angle (140°) videocolonoscope - Olympus (Tokyo, Japan) was used with a high-definition 1080-line screen - Olympus (OEV191H, Tokyo, Japan). In the HD group, colonoscopy was performed with a wide-angle (170°), high-resolution videocolonoscope - Olympus (CFH180AL, Tokyo, Japan) with the same HD screen. |
| Intervention type | Other |
| Primary outcome measure(s) |
Performance of the colonoscopy, measured 10/10/2008. |
| Key secondary outcome measure(s) |
Detection of small polyps (less than or equal to 5 mm), measured 10/10/2009. |
| Completion date | 10/10/2008 |
