Implantation of metallic stents for malignant biliary strictures has been recognized to be effective alternatives.
To show our experience in metallic stents for palliation of malignant biliary strictures.
Seventy three patients (38 males, 35 females, mean age 64.26) with malignant biliary strictures have been treated by implantation of metallic stents. Causes of obstruction were pancreatic carcinoma (23/73, 31.5%), bile duct carcinoma (31/73, 42.5%), carcinoma of ampula of Vater (11/73, 15%) and Klatskin tumor (3/73, 4.1%).
Endoscopic procedure was successful in all cases. Neither procedure-related morbidity nor mortality was observed. Life surviving curve was 9 months and showed significant difference (p < 0.0071) in patients with carcinoma of ampula of Vater.
Self-expanding metal endoprosthesis is a recognized method of palliation in malignant biliary obstruction. It efficiently relieves jaundice and generally improves comfort and nutritional status during the patient's remaining lifetime. The metallic stents are advantageous in patients surviving 6 months or less.
金属支架植入术治疗恶性胆管狭窄已被公认为是一种有效的替代方法。
展示我们使用金属支架缓解恶性胆管狭窄的经验。
73例恶性胆管狭窄患者（男38例，女35例，平均年龄64.26岁）接受了金属支架植入治疗。梗阻原因包括胰腺癌（23/73，31.5%）、胆管癌（31/73，42.5%）、 Vater壶腹癌（11/73，15%）和肝门部胆管癌（3/73，4.1%）。
所有病例的内镜操作均成功。未观察到与操作相关的并发症或死亡。生存曲线为9个月，Vater壶腹癌患者有显著差异（p < 0.0071）。
自膨式金属内支架是治疗恶性胆管梗阻的一种公认的姑息方法。它能有效缓解黄疸，通常可改善患者余生的舒适度和营养状况。金属支架对生存期在6个月或更短的患者有利。
