目的 研究影响恶性胆道梗阻金属支架、内涵管置入术后患者生存和支架开通的因素。方法 对 95例恶性胆道梗阻患者金属支架、内涵管置入术后作随访调查 ,应用SPSS 10 .0统计软件对影响其术后的 2 3项可能影响因素作Cox模型的多因素分析。结果 支架类型、梗阻段、肿瘤大小和分期为影响患者术后生存的因素 (P≤ 0 .0 5 ) ,支架类型和肿瘤大小为影响患者术后支架开通的因素 (P <0 .0 5 )。结论 支架类型和肿瘤大小是影响恶性胆道梗阻患者支架置入术后患者生存期和支架开通期的主要因素。
Objective To study the factors affecting the survival and stent opening of malignant biliary obstruction with metal stents and endoprosthesis. Methods 95 cases of malignant biliary obstruction in patients with metal stents and endoprostheses were followed up for follow-up surveys. SPSS 10 statistical software was used to analyze the multifactorial factors affecting the postoperative potential of the Cox model. Results The type of stent, obstruction segment, tumor size and staging were the factors affecting postoperative survival (P ≤ 0.05). The stent type and tumor size were the factors influencing the postoperative stent opening (P < 0.05). . Conclusion The type of stent and tumor size are the main factors affecting the survival time and stent opening period of patients with malignant biliary obstruction after stent implantation.
