胆道支架置入是治疗胆道恶性梗阻的重要方法。根据不同的适应证可以选择塑料支架或金属支架,置入途径主要有EST和PTCD途径。胆道支架的移位、堵塞以及胆道感染是支架置入后的常见并发症,而以腔内放射为主的后续联合治疗在一定程度上能抑制局部肿瘤的生长,延长支架通畅时间。对于胆胰管并存梗阻的患者,最好同时行胆管及胰管双支架联合引流。胆道支架置入是有效解除胆道梗阻的方法,其效果可与外科分流术相媲美,对中晚期恶性胆道梗阻患者不失为一种较好的姑息性治疗手段。
Biliary stent placement is an important method of treatment of malignant biliary obstruction. According to different indications can choose plastic stent or metal stent, the main means of placement EST and PTCD pathway. Biliary stent displacement, blockage and biliary tract infection is a common complication after stent implantation, and the subsequent combination therapy of intracavitary radiotherapy to a certain extent, can inhibit the growth of local tumors and prolong stent patency. For patients with pancreaticobiliary obstruction, it is best at the same time biliary and pancreatic duct double stent drainage. Biliary stent placement is an effective way to relieve biliary obstruction, the effect comparable with the surgical shunt, the late malignant biliary obstruction patients may be a better palliative treatment.
