结直肠肿瘤内镜诊断的难度主要取决于其大体形态。由于浅表扁平型和凹陷型肿瘤通常在内窥镜下通过其表面微弱的红色来检测，因此我们评估了采用的血红蛋白指数颜色强调系统在非颗粒（NG）型横向扩散肿瘤（LST）病变中的有用性。 NG 型 LST 仅由平坦表面组成，没有任何结节。 NG型LST病变中Tis频率为20.2%，T1/T2频率为15.7%。结果表明，采用的血红蛋白指数颜色强调系统能够强调颜色层次，红度和白度在该系统中得到加强。红色和白色的程度取决于强调级别，并且在 NG 型 LST 病变中，5 级的颜色清晰度比 3 级更清晰。因此，该系统可能有助于扁平型和凹陷型结直肠病变的内窥镜诊断。
The difficulty in an endoscopic diagnosis of colorectal tumors depends mainly on their gross configuration. As the superficial flat type and depressed type tumors are usually detected endoscopically by a faint redness on their surface, we evaluated the usefulness of an adopted type hemoglobin index color emphasis system in the lesion of a non‐granular (NG) type laterally spreading tumor (LST). The NG‐type LST was composed of only a flat surface without any nodules. The frequency of Tis was 20.2% and that of T1/T2 was 15.7% in the lesion of the NG‐type LST. Results showed that the adopted type hemoglobin index color emphasis system can emphasize the color level, as the redness and whiteness intensified in this system. The degree of redness and whiteness depended on the emphasis level, and the clarity of colors became clearer in level 5 than level 3 in a lesion of the NG‐type LST. This system may thus contribute to the endoscopic diagnosis of flat and depressed type colorectal lesions.
