| Comparison between success rates of conventional endoscopy plus chromoendoscopy and conventional endoscopy plus magnifying endoscopy with NBI in delineating early gastric cancer. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is intended to determine differences in limitations of conventional endoscopy plus chromoendoscopy and conventional endoscopy plus magnifying endoscopy with NBI in delineating early gastric cancer and to compare correct diagnosis rates of the two techiniques according to clinicopathological findings. In addition, correct diagnosis rates will be compared according to the conditions with high- and low-confidence prediction. | — |
