Previous clinical trials suggest that adding non-selective beta-blockers improves the efficacy of endoscopic band ligation (EBL) in the prevention of recurrent bleeding, but no study has evaluated whether EBL improves the efficacy of beta-blockers + isosorbide-5-mononitrate. The present study was aimed at evaluating this issue in a multicentre randomised controlled trial (RCT) and to correlate changes in hepatic venous pressure gradient (HVPG) during treatment with clinical outcomes
158 patients with cirrhosis, admitted because of variceal bleeding, were randomised to receive nadolol+isosorbide-5-mononitrate alone (Drug: n = 78) or combined with EBL (Drug+EBL; n = 80). HVPG measurements were performed at randomisation and after 4-6 weeks on medical therapy.
Median follow-up was 15 months. One-year probability of recurrent bleeding was similar in both groups (33% vs 26%: p = 0.3). There were no significant differences in survival or need of rescue shunts. Overall adverse events or those requiring hospital admission were significantly more frequent in the Drug+EBL group. Recurrent bleeding was significantly more frequent in HVPG non-responders than in responders (HVPG reduction >or=20% or <or=12 mm Hg). Among non-responders recurrent bleeding was similar in patients treated with Drugs or Drugs+EBL.
Adding EBL to pharmacological treatment did not reduce recurrent bleeding, the need for rescue therapy, or mortality, and was associated with more adverse events. Furthermore, associating EBL to drug therapy did not reduce the high rebleeding risk of HVPG non-responders. ISRCTN26221020.
既往临床试验表明,加用非选择性β受体阻滞剂可提高内镜下套扎术(EBL)预防再出血的疗效,但尚无研究评估EBL是否能提高β受体阻滞剂+5-单硝酸异山梨酯的疗效。本研究旨在通过一项多中心随机对照试验(RCT)评估这一问题,并将治疗期间肝静脉压力梯度(HVPG)的变化与临床结局相关联。
158例因静脉曲张出血入院的肝硬化患者被随机分为单独接受纳多洛尔+5-单硝酸异山梨酯治疗组(药物组:n = 78)或联合EBL治疗组(药物+EBL组:n = 80)。在随机分组时以及药物治疗4 - 6周后进行HVPG测量。
中位随访时间为15个月。两组的再出血1年概率相似(33%对26%:p = 0.3)。在生存率或抢救性分流需求方面无显著差异。药物+EBL组的总体不良事件或需要住院治疗的不良事件明显更频繁。HVPG无反应者的再出血明显比有反应者更频繁(HVPG降低≥20%或≤12 mmHg)。在无反应者中,接受药物治疗或药物+EBL治疗的患者再出血情况相似。
在药物治疗基础上加用EBL并不能降低再出血、抢救治疗需求或死亡率,且与更多不良事件相关。此外,将EBL与药物治疗联合使用并不能降低HVPG无反应者的高再出血风险。ISRCTN26221020。
