John Nathanson: 结肠镜检查是一个敏感话题,许多人对其存在误解。它不仅可以诊断常见的胃肠道问题,更重要的是可以筛查结肠癌。 准备工作因医生而异,通常包括在检查前一天改变饮食并服用泻药。充分的准备至关重要,因为这决定了检查的彻底性,医生可以更好地寻找癌前病变。为了让准备过程更容易,建议在检查前几天逐渐改变饮食,并冷饮泻药。在检查前几天应减少纤维摄入,因为高纤维饮食会使肠道准备更困难。 结肠镜检查过程中,患者会接受静脉注射镇静剂,医生会使用摄像头检查结肠内壁,如有异常情况,会进行活检或切除。虽然建议进行镇静,但患者可以选择不进行麻醉。结肠镜检查通常不会引起疼痛,大多数患者几乎没有不适感,术后不适感也很小。 45至75岁的人应该进行结肠镜检查以筛查结肠癌,即使感觉健康也应该进行检查。虽然45岁开始筛查是一个好时机,但如果存在家族史或高危遗传状况,则可能需要更早开始筛查;如有任何令人担忧的新症状,应咨询医生。结肠镜检查不仅可以检测结肠癌,还可以预防结肠癌,因为可以切除癌前息肉。大多数患者认为检查过程并不困难。 Rachel Feltman: 作为主持人,我主要负责引导访谈,提出问题,并对John Nathanson医生的回答进行总结和梳理,以帮助听众更好地理解结肠镜检查的相关知识。
