摘要
应用镍铁形状记忆合金胆道内支架治疗10例胆管良、恶性狭窄,包括6例肝门部胆管癌,2例胆囊癌,1例肝癌和1例右肝管损伤性狭窄。术前病人的血清总胆红素值95.8～520μmol/L,平均值338.5μmol/L。8例在放置支架后2～6周黄疸消退,2例在住院期间分别死于感染性休克和肝功能衰竭。对肝门部胆管癌行姑息性治疗时,置入记忆合金内支架比PTBD外引流更具优点。
Ten patients with begnin or malignant bile duct stenosis were treated with sharp-memory nickel-titanium alloy endoprotheses,including 6 patients with hilar cholangioearcinoma, 2 patients with gallbladder carcinoma, 1 patient with hepatocellular carcinoma, and 1 patient with right hepatic duct stricture due to operative injury. Total serum bilirubin levels ranged from 95.8 to 520 μmol/L with a mean of 338.5μmol/L before stent insertion,but jaundice disappeared completely within 2 to 6 weeks in 8 patients after stent placement. During hospitalization 2 patients died of septic shock and liver function failure respectively. We consider that the use of sharp-memory alloy endoprotheses in paliative treatment of hilar cholangiocar-cinoma advantageous in comparison with percutaneous transhepatic biliary drainage.
