胆胰内支架抗阻塞研究进展

study progress of anti-obstruction of pancreaticobiliary stents

胆胰内支架对解除胆胰良恶性狭窄尤其是肝门部肿瘤所致的恶性阻塞性黄疸效果显著,但阻塞依然是支架的主要并发症。肿瘤过度生长、胆汁成分、胆汁流动速度、细菌大量繁殖和支架的原料及形式参与了支架的阻塞。

The pancreaticobiliary stent placement is quite effective in the palliative treatment of malignant obstructive jaundice resulting from pancreaticobiliary benign or malignant stricture especially hilar tumor, but the occlusion of the stent is still the major complication. Overgrowth of tumor, elements of bile, bile flow rates, bacterium infection, materials and shapes of the stent participate in stent occlusion.
