晚期恶性阻塞性黄疸常有双重梗阻,多不能行Whipple根治性切除术,但在病人和医疗条件允许的情况下应尽量争取做内引流术如:胃空肠吻合术和硅胶管搭桥行肝管—空肠腹膜后吻合术,从而提高病人的生存质量。而我们近10年来对不能做根治又不适应做内引流术的晚期胰头癌及Vater氏壶腹癌的9例采取了改良引流术,收到了较好的效果。手术方法:开腹探 Late malignant obstructive jaundice often have double obstruction, more than the possibility of radical Whipple radical resection, but patients and medical conditions should be allowed to try to do internal drainage such as: gastrojejunostomy and silicone tube bypass line - Retroperitoneal jejunal anastomosis improves patient quality of life. In the past 10 years, we have adopted improved drainage for advanced pancreatic head cancer and Vater’s ampullary carcinoma, which cannot be cured and are not adapted to internal drainage. This has received good results. Surgical methods: open exploration
