In 126 patients with liver cirrhosis treated electively with transjugular intrahepatic portosystemic stent shunt (TIPS) to prevent variceal rebleeding, the portosystemic pressure gradient decreased by 60%. In spite of this incomplete effect the risk for variceal rebleeding was still under 20% after 2 years. Only 1 patient died of variceal rebleeding. Shunt insufficiency occurred in 50%, mainly during the first year, but shunt function was restored in nearly all cases by radiologic intervention, i.e., redilatation or implantation of an additional stent. During the follow-up of 16 +/- 9 months, 21 patients (17%) died, one-third of them from progressive liver failure aggravated in 4 cases by severe drinking. De novo hepatic encephalopathy was observed in 10%, especially in older patients and patients with impaired liver function before TIPS. In such patients it is recommended that the shunt be dilated to 0.8 cm at most, and the TIPS procedure can be combined with transjugular embolization of the varices. The advantages of TIPS over both endoscopic sclerotherapy and drug treatment must be clarified in randomized studies, which have already been initiated in several centers.
在126例因预防静脉曲张再出血而接受经颈静脉肝内门体分流术(TIPS)择期治疗的肝硬化患者中,门体压力梯度下降了60%。尽管效果不完全,但2年后静脉曲张再出血的风险仍低于20%。仅有1例患者死于静脉曲张再出血。分流功能不全发生率为50%,主要发生在第一年,但几乎所有病例通过放射学干预,即再次扩张或植入额外支架,分流功能得以恢复。在16±9个月的随访期间,21例患者(17%)死亡,其中三分之一死于进行性肝功能衰竭,4例因严重酗酒而加重。新发肝性脑病发生率为10%,尤其在老年患者和TIPS术前肝功能受损的患者中。对于此类患者,建议将分流道扩张至最大0.8 cm,并且TIPS手术可与经颈静脉曲张静脉栓塞术联合进行。TIPS相对于内镜硬化治疗和药物治疗的优势必须在随机研究中加以明确,目前已有多个中心启动了此类研究。
