EASL 2014 :TIPS10mm支架控制门脉高压更效果更优

2014-04-14 佚名 dxy

一个单中心、小样本的随机临床试验(RCT)曾显示,对于肝硬化难治性腹水的患者,使用直径为8mm的支架(聚四氟乙烯膨体覆盖)行TIPS手术并不能有效控制门脉高压,且容易引起并发症。为了进一步从临床应用方面证实此项研究,来自意大利巴勒莫的Luca等进行了一项回顾性研究,其结果公布于2014年4月9日-4月13日在伦敦举行的EASL2014会上。 研究选择了连续的171例采用直径8mm或直径10mm支架

一个单中心、小样本的随机临床试验(RCT)曾显示,对于肝硬化难治性腹水的患者,使用直径为8mm的支架(聚四氟乙烯膨体覆盖)行TIPS手术并不能有效控制门脉高压,且容易引起并发症。为了进一步从临床应用方面证实此项研究,来自意大利巴勒莫的Luca等进行了一项回顾性研究,其结果公布于2014年4月9日-4月13日在伦敦举行的EASL2014会上。

研究选择了连续的171例采用直径8mm或直径10mm支架行TIPS手术以治疗肝硬化难治性腹水的患者,其中111例患者采用8mm支架,60例患者采用10mm支架。术后研究人员对这些患者进行了随访,平均随访时间为16.2±8.5月。

结果显示,比较两组患者在年龄、性别、病因、Child-Pugh评分、MELD、既往肝性脑病史、静脉曲张破裂出血、自发性腹膜炎、食管胃底静脉曲张及门脉压力基线水平等方面均无统计学差异。10mm支架组门脉血栓形成的发生率高于8mm支架组(43.4% VS 5.4%)。TIPS手术后,10mm支架组门脉压力降低的程度显著高于8mm支架组(10.4 VS 8.7mmHg)。

两组患者3个月内需行腹腔穿刺术的概率无统计学差异(23% VS 18%)。但从长期来看,8mm支架组的概率较高(58% VS 31%)。两组患者总的肝性脑病、重度肝性脑病(Ⅲ期和Ⅳ期)、新发肝性脑病或原有肝性脑病加重、急性肝性脑病、慢性肝性脑病及首次出现肝性脑病的累积可能性相近。

同样地,两组患者在新发静脉曲张破裂出血、自发性腹膜炎、TIPS再狭窄、Child-Pugh评分、MELD、是否需肝移植、总的生存率及未行移植患者的生存率方面的比较也无统计学差异。

研究表明,10mm支架较8mm支架可更好的降低门脉压力,且两者肝性脑病及其他并发症的发生率无统计学差异,因而该研究支持使用10mm聚四氟乙烯膨体覆盖支架行TIPS手术以治疗肝硬化难治性腹水。
