Variceal bleeding is a life-threatening complication of portal hypertension. The recommended treatment includes the early administration of a vasoactive drug. Vapreotide is a somatostatin analogue with a different receptor affinity to octreotide. It decreases portal pressure and blood flow of collateral circulation in rats with cirrhosis. The pivotal study of early administration of vapreotide in patients with cirrhosis and variceal bleeding has shown a significant improvement in bleeding control and, in the subset of patients with significant bleeding, a significant reduction in mortality. In addition, a meta-analysis of four randomized studies has shown a significant improvement in bleeding control. Vapreotide administrated via the intravenous route is simple to use, with practically no contraindications and few, usually minor, side effects.
静脉曲张出血是门静脉高压的一种危及生命的并发症。推荐的治疗方法包括早期使用血管活性药物。伐普肽是一种生长抑素类似物,与奥曲肽具有不同的受体亲和力。它可降低肝硬化大鼠的门静脉压力和侧支循环血流量。对肝硬化合并静脉曲张出血患者早期使用伐普肽的关键研究表明,在出血控制方面有显著改善,并且在大出血患者亚组中,死亡率显著降低。此外,四项随机研究的荟萃分析表明,在出血控制方面有显著改善。静脉注射伐普肽使用简便,几乎没有禁忌证,副作用通常较少且轻微。
