镍钛记忆合金胆道内支架治疗恶性高位胆管梗阻

SHARP MEMORY NICKEL-TITANIUM ALLOY ENDOPROSTHESES FOR THE TREATMENT OF MALIGNANT HILAR BILIARY STRICTURES

应用镍钛形状记忆合金胆道内支架管治疗15例胆道恶性狭窄或梗阻，其中肝门部胆管癌11例，胆囊癌3例，肝门部肝癌1例。所有病人术前均有严重梗阻性黄疸（血清总胆红素平均值286．5μmo/L），经剖腹术或PTCD途径放置内支架管后14例黄疸在1～6周内消退，1例在住院期间死于多器官功能衰竭。对恶性高位胆道梗阻或狭窄所引起的黄疸行姑息性减黄治疗时，置入镍钛形状记忆合金支架作内引流是较为理想的治疗方法。

Sharp memory nickel-titanium alloy endoprostheses were used to treat 15 patients with malignant hilar biliary sthctures or obstructious, including 11 patients with hilar cholangiocarcinoma, three patients with gallbladder carcinorna, and one patient with hepatocellular carcinoma. All patients had severe obstructive jaundice before the treatment (mean serum bilirubin level was 286. 5μmol/L.In 14 patients, jaundice disaPPeared one to six weeks after the insertion of alloy endoprosheses. One patient died of MOF during hospitalization. Results indicate that sharp memory nikel-titanium alloy endoprostheses are an ideal Palliative treatment for jaundice of malignant hilar biliary obstructions or strictures.
