0 = Unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared. 1 = Portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool and/or opaque liquid. 2 = Minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well. 3 = Entire mucosa of colon segment seen well with no residual staining, small fragments of stool or opaque liquid. The wording of the scale was finalized after incorporating feedback from three colleagues experienced in colonoscopy. Ottawa 肠道评分标准 对各节段肠道的准备质量进行评估。总分为14分（包括0分）这一评分准则包括了两个部分：一为肠道清洁度（0至12分），分别对左侧（直肠、乙状结肠、降结肠），中间（横结肠），右侧（升结肠、盲肠、回肠末端）进行评分；二为整个肠腔液体残余量（0至2分）。 优（0分）：肠腔残存微量液体，肠粘膜充分暴露 良（1分）：少量液体残余，良好的肠粘膜暴露 一般（2分）：少量液体伴有微量固体剩余，基本不影响观察 差（3）：存在大量固体粪便需要冲洗，对肠粘膜的观察收到影响 极差（4）：需要重新准备 液体残存量：少量（0分）；中量（1分）；大量（2分） * * Boston肠道准备评分标准 由波士顿医学中心研究制定在2010年必威体育精装版提出，并可能成为国际统一的肠道准备评分标准。这一标准也是分别对三部分（左，中，右）结肠进行评分 0分：大量固体粪便残存，需重新准备肠道。 1分：部分肠段存在液体及半固态粪便，影响观察 2分：少量粪便残存，不影响观察 3分：微量或无固液态粪便残存，观察效果优 Calderwood AH, et al.
