METHODS： A total of 233 patients with malignant billan/obstruction were treated in our hospital with PTBD by placement of metallic stents and/or plastic tubes. After PTBD, 49 patients accepted brachytherapy or extraradiation therapy or arterial infusion chemotherapy. The patients were followed up with clinical and radiographic evaluation. The survival and stent patency rate were calculated by Kaplan-Meier survival analysis. RESULTS： Twenty-two patients underwent chemotherapy （11 cases of hepatic carcinoma, 7 cases of pancreatic carcinoma, 4 cases of metastatic lymphadenopathy）, and 14 patients received radiotherapy （10 cases of cholangiocardnoma, 4 cases of pancreatic carcinoma）, and 13 patients accepted brachytherapy （7 cases of cholangiocarcinoma, 3 cases of pancreatic carcinoma, 4 cases of metastatic lymphadenopathy）. The survival rate of the local tumor treatment group at 1, 3, 6, and 12 months was 97.96%, 95.92%, 89.80%, and 32.59% respectively, longer than that of the non treatment group. The patency rate at 1, 3, 6, and 12 months was 97.96%, 93.86%, 80.93%, and 56.52% respectively. The difference of patency rate was not significant between treatment group and non treatment group. CONCLUSION： Our results suggest that local tumor therapy could prolong the survival time of patients with malignant biliary obstruction, and may improve stent patency.展开更多
