The feces remaining within the gastrointestinal tract (residual feces) often give the appearance of red- to scarlet-colored superficial raised lesions (Fig. 15.1a, b), and bowel preparation fluid is seen as a reddish liquid (Fig. 15.1c, d) using NBI. Either may be confused with blood, but switching over from NBI to WLI makes it easy to differentiate between them.
