目前医学对于恶性梗阻性黄疸患者大多数使用胆道支架行姑息性引流治疗,该种支架只起到物理性扩张胆道,引流胆汁的作用,无法阻止肿瘤长入支架造成短时间内再堵塞,使患者获得远期生存获益。因此新型胆道支架相比之下有无法比拟的优势,其通过支架本身的复合材料或特殊的覆膜结构等等特性产生局部抗肿瘤作用,从而抑制肿瘤的生长。新型支架的兴起有可能成为学术界的研究热点,日后成为恶性梗阻性黄疸患者治疗的首选方式。
At present, the majority of patients with malignant obstructive jaundice in the treatment of palliative drainage with biliary stent, the stent only play a physical expansion of the bile duct, the role of drainage bile, can not stop the tumor into the stent caused by a short time to plug, so that patients Gain long-term survival benefits. Therefore, compared with the novel biliary stent incomparable advantages, through the stent itself or a special composite structure of the membrane structure and other characteristics of local anti-tumor effect, thereby inhibiting tumor growth. The rise of the new stent may become a research hotspot in the academic community and become the preferred method of treatment for patients with malignant obstructive jaundice in the future.
