Transjugular intrahepatic portosystemic shunt (TIPS), a new technique for the treatment of portal hypertension, has been successful in preliminary studies to treat acute variceal hemorrhage and to prevent variceal rebleeding. The purpose of this multicenter, randomized controlled trial is to compare the efficacy of TIPS with that of endoscopic sclerotherapy in the prevention of variceal rebleeding in cirrhosis. Eighty-one cirrhotic patients, with endoscopically proven variceal bleeding, were randomized to either TIPS (38 patients) or endoscopic sclerotherapy (43 patients). Randomization was stratified according to the following: if bleeding occurred < 1 week (stratum I); if bleeding occurred 1 to 6 weeks (stratum II); and if bleeding occurred 6 weeks to 6 months (stratum III) before enrollment. Follow-up included clinical, biochemical, Doppler Ultrasound, and endoscopic examinations every 6 months. During a mean follow-up of 17.7 months, 51% of the patients treated with sclerotherapy and 24% of those treated with TIPS rebled (P = .011). Mortality was 19% in sclerotherapy patients and 24% in TIPS patients (P = .50). Hepatic encephalopathy (HE) developed in 26% and 55%, respectively (P = .006). A separate analysis of the three strata showed that TIPS was significantly more effective than sclerotherapy (P = .026) in preventing rebleeding only in stratum I patients. TIPS is significantly better than sclerotherapy in preventing rebleeding only when it is performed shortly after a variceal bleed; however, TIPS does not improve survival and is associated with a significantly higher incidence of HE. The overall performance of TIPS does not seem to justify the adoption of this technique as a first-choice treatment to prevent rebleeding from esophageal varices in cirrhotic patients.
经颈静脉肝内门体分流术(TIPS)是一种治疗门静脉高压的新技术,在初步研究中已成功用于治疗急性静脉曲张出血和预防静脉曲张再出血。这项多中心随机对照试验的目的是比较TIPS与内镜硬化治疗在预防肝硬化患者静脉曲张再出血方面的疗效。81例经内镜证实有静脉曲张出血的肝硬化患者被随机分为TIPS组(38例)或内镜硬化治疗组(43例)。随机分组按以下情况分层:入组前出血发生时间<1周(I层);出血发生时间为1至6周(II层);出血发生时间为6周至6个月(III层)。随访包括每6个月进行一次临床、生化、多普勒超声和内镜检查。在平均17.7个月的随访期间,硬化治疗组51%的患者和TIPS组24%的患者出现再出血(P = 0.011)。硬化治疗组患者的死亡率为19%,TIPS组为24%(P = 0.50)。肝性脑病(HE)分别在26%和55%的患者中发生(P = 0.006)。对三个层的单独分析表明,仅在I层患者中,TIPS在预防再出血方面显著优于硬化治疗(P = 0.026)。仅在静脉曲张出血后不久进行TIPS时,其在预防再出血方面明显优于硬化治疗;然而,TIPS并不能提高生存率,且与较高的HE发生率相关。TIPS的总体表现似乎不足以证明将该技术作为预防肝硬化患者食管静脉曲张再出血的首选治疗方法。
