【摘要】 20世纪末期结肠支架用于结肠癌急性梗阻的治疗,肠道减压及恢复获得成功,自此,治疗左半结肠癌急性梗阻除急诊手术外,有了一种新的途径。结肠支架置入术应用于临床上的治疗,仍在不断的探讨研究,不仅在左半结肠癌急性梗阻的姑息性治疗效果满意,作为手术桥梁方式也发挥了重要的作用,但近年来不同的研究结果,使结肠支架的应用仍有很大的局限性。

【Abstract】 Since the late 20th century,colonic stent has been used for the treatment of acute obstruction of colon cancer,and has achieved success in intestinal decompression and recovery.Since then,the treatment of acute obstruction of left colon cancer has a new approach besides emergency surgery.The clinical application of colon stent in the obstructed left colon cancer is ongoing research,not only in palliative treatment achieved satisfactory results,but also played an important role as a bridge to surgery,but different results in recent years,the application of the stent is still a great limitation.

左半结肠癌急性梗阻(obstructed left colon cancer,OLCC)是临床上最为常见的结肠梗阻类型,因梗阻后的病理生理变化迅速,一经诊断,宜尽早积极处理。外科急诊手术(emergency surgery,ES)一直是OLCC的传统治疗方式,但由此带来的是高并发症发生率和死亡率及临时性或永久性的造口。Dohmoto[1]和Tejero等[2]于20世纪末期首先描述了结肠支架用于结肠癌急性梗阻的治疗,肠道减压及恢复获得成功,目前,结肠支架置入术被推荐作为晚期肿瘤姑息性治疗的首选方式[3],但因其安全性和可能带来的肿瘤学相关风险,在作为手术桥梁(bridge to surgery,BTS)方面依然存有争议。现查阅国内外相关资料,就结肠支架置入术的特点、在OLCC姑息性治疗中及作为手术桥梁的应用等综述如下。
1 结肠支架置入术的特点
结肠支架置入术是在X线下使用内镜或直接通过输送系统将支架通过肛门置于肠腔狭窄或阻塞部位,使得肠道减压,重新恢复通畅的一种治疗方式。……
