Malignancy
NO
Patients will undergo colonoscopy using white light imaging or LCI. Adenoma detection rate, adenoma detection number per patient, polyp number in each polyp sizes and location and insertion time and withdrawal time are examined.

The LCI and WLI groups comprised 494 and 501 patients, respectively.The mean adenoma number per patient was significantly higher in the LCI group than in the WLI group (1.07 vs. 0.88, p=0.04).
However, the adenoma detection rate was 47.0% in the LCI group and 47.9% in the WLI group, with no significant difference.
