结直肠癌的治疗

ID: ANH17199chis
医学动画文字记录:结直肠癌的治疗包括外科手术、化学疗法和放射疗法。结肠镜检查过程中可能会切除早期癌症或息肉。在检查过程中,将通过肛门插入一根软管。在大多数情况下,如果发现息肉,就会将其切除。如果发现小面积的癌症,也会切除。对于较大范围的癌症,可能需要进行外科手术以切除病变的大肠。外科医生可能会切除部分结肠、部分或全部直肠。附近的组织,如淋巴结也可能被切除,以检查癌症是否已经扩散到那里。在大多数情况下,大肠的残端会重新吻合。但是,有时医生不会立即吻合残端,而是进行手术将大肠的最顶端吻合到腹部皮肤的开口上,而末端用缝合钉或缝线缝合。粪便通过这个皮肤上的新开口排入袋子中。通常,这个开口是暂时的。如果是暂时的,后续会进行手术重新吻合大肠两端。也可以在外科手术之前或之后进行化学疗法、放射疗法或两种治疗都采用。化学疗法使用药物来攻击并杀死癌细胞。放射疗法通常与化学疗法一起进行。放射治疗中的高能射线攻击并破坏癌细胞。也可能建议采取其他方法来治疗结直肠癌。如果你有任何问题,请咨询医生。
