目的观察经内镜下胆管内引流术治疗良恶性胆管梗阻病人的效果。方法经内镜下逆行胆管造影,根据胆管狭窄的情况放置不同的胆管支架。术后观察病人的黄疸、腹痛和发热等症状,并复查肝功能等。结果36例良恶性胆管梗阻,塑料支架置入成功率为96.4%,金属支架成功率为100%,无支架术相关死亡者。结论经内镜下逆行胆管内引流手术要求的条件低,创伤小,引流效果好,是治疗胆管梗阻的首选引流方法,值得进一步推广。 Objective To observe the effect of endoscopic biliary drainage in patients with benign and malignant biliary obstruction. Methods By endoscopic retrograde cholangiography, different biliary stents were placed according to the situation of biliary stricture. Postoperative observation of patients with jaundice, abdominal pain and fever and other symptoms, and review of liver function. Results 36 cases of benign and malignant biliary obstruction, plastic stent placement success rate was 96.4%, metal stent success rate was 100%, no stent-related death. Conclusion The endoscopic retrograde cholangiopancreatography requires low drainage conditions, small trauma and good drainage. It is the first choice of drainage for bile duct obstruction and should be further popularized.
