肝门胆管癌虽属局部进行性病症,但向胆管,脉管内直接浸润。确诊后多不能手术根治或抗癌剂治疗。作者试用外部和术中照射。理想的疗法是腔内和组织内照射。大阪大学放射科把~(192)Ir 丝插到经皮的胆管插管内进行胆道腔内照射和外照射併用收到良好效果?颊吣?7岁,超声检查左右肝内胆管扩张;疑造影右肝管阻塞、胆囊管边缘不整。疑为肝门胆管癌用6MV-X 线,直线加速器,照射野11×9cm,病灶深8cm,前后二野3300rad/15回。放疗结束后四天行剖腹手术,见近肝门处肿瘤粘着存在难以测量大小,肝左叶边缘有直径4cm 肿瘤, Although it is a locally progressive disease, hilar cholangiocarcinoma directly infiltrates into bile ducts and vessels. After the diagnosis can not be radical surgery or anti-cancer treatment. The author tried external and intraoperative irradiation. The ideal therapy is intraluminal and intra-tissue irradiation. The Department of Radiology, Osaka University inserted ~(192)Ir wire into a percutaneous bile duct to perform biliary luminal irradiation and external radiation and received good results. The buccal palsy was 7 years old. Ultrasound examination revealed intrahepatic bile duct dilatation; The right hepatic duct is obstructed and the cystic duct is not well-defined. Suspected for hilar cholangiocarcinoma with 6MV-X line, linear accelerator, radiation field 11 × 9cm, lesion depth 8cm, before and after the field 3300rad / 15 back. After the end of radiotherapy, laparotomy was performed four days later. It was difficult to measure the size of the tumor near the hilum, and there was a 4cm diameter tumor on the left edge of the liver.
