病例在导丝辅助下利用OTSC成功实现

导读

今天和大家分享一篇发表在Endoscopy上的病例。患者因结肠憩室出血入院治疗,在对其使用钛夹止血失败后,使用内镜外(OTS)吻合夹成功实现了憩室止血。在该治疗的过程中,因为OTS吻合夹会妨碍内镜视野,所以研究人员在内镜顶端的活检钳道插入了一根导丝,通过导丝辅助的方法将顶端连接OTS吻合夹的内镜快速推进至升结肠中,成功实现了止血。文中还附有详细视频,一起来看。

在导丝辅助下利用OTSC实现升结肠憩室出血的止血

患者,男性,61岁,因结肠憩室出血入院治疗。虽然入院第2天使用5个钛夹实现了盲肠止血,但第3天患者又再次出血,因此对患者再次进行了结肠镜检查。在这次结肠镜检查的过程中,研究人员先取出了之前放置的钛夹,然后放置了一根0.英寸的胆管导丝,随后退镜([图1]),退镜后将一个内镜外(OTS)吻合夹(OvescoEndoscopyAG)连接到内镜顶端。然后沿导丝将内镜重新插入盲肠。使用OTS吻合夹实现止血([图2];[视频1])。本次干预后患者病情好转,入院第9天后出院。
