医学动画文字记录:腹腔镜结肠切除术是切除部分或全部大肠的外科手术。大肠是消化道一系列空腔器官的最后一部分。大肠的一部分,称为结肠,从未消化的食物中吸收水分,产生称为粪便的废物,这些废物通过肛门排出体外。结肠切除术通常用于治疗使结肠发生炎症改变的疾病,例如克罗恩病、溃疡性结肠炎或憩室炎、肠梗阻、结肠癌或结肠损伤。手术开始后,外科医生会在肚脐附近做一个小切口,并插入导管,这个切口称为孔。通过这个孔向腹腔泵入气体使腹部膨胀,为医生创造手术空间。根据结肠切除术的类型,可能会做一个或多个额外的切口。然后将通过这些切口插入相机和手术器械。在找到结肠的受损部位后,医生会将其与腹部其他器官分离开来。接下来,结肠受损部分将通过其中一个切口切除取出。在大多数情况下,用缝线或缝合钉将结肠剩余的健康末端吻合在一起。但有时可能会在此时进行结肠造口术,以便使结肠愈合的时间更加充分。在此过程中,医生将用缝线或缝合钉闭合一端。另一端连接到腹部外侧,形成一个称为造口的开口。医生将在造口上放置一个结肠造口袋,以收集结肠中的粪便。在大多数情况下,结肠造口术是暂时的。后续进行手术将大肠末端重新吻合。如果你对腹腔镜结肠切除术有任何疑问,请咨询医生。
