目的 评价植入镍钛记忆合金支架治疗恶性胆道梗阻的疗效。方法 对16例恶性胆道梗阻患者,采用经手术及介入方法植入镍钛记忆合金胆道支架。结果 术后1个月内死亡1例,15例黄疸完全解除。随访15例,12例术后平均生存13.1个月。结论 植入镍钛合金胆道支架可提高姑息切除的疗效;对不能切除病灶患者,支架植入可解除黄疸,改善生活质量。
Objective To evaluate the effect of implanting NiTi memory alloy stent on malignant biliary obstruction. Methods Sixteen patients with malignant biliary obstruction were implanted with nickel-titanium memory alloy biliary stents by means of operation and intervention. Results 1 case died within 1 month after operation, and 15 cases were completely relieved of jaundice. Fifteen patients were followed up, and 12 patients survived an average of 13.1 months after operation. Conclusion Ni-Ti alloy biliary stent implantation can improve the efficacy of palliative resection; patients who can not be removed, stenting can relieve jaundice and improve the quality of life.
