随着胆管癌发病率的上升,胆管恶性狭窄日益增多,对于难以手术治愈及不适合手术者,胆道内支架置入术是一种较新的介入治疗方法,可取代胆管内、外引流术。目前,胆道内支架置入术有二种途径,即经内镜和经皮肝穿刺,前者因路径远,尤其对肝门区胆管狭窄及狭窄角度较大者,操作难度大,后者路径短且可行选择性插管,成功率可在90％以上。我们采用经皮肝穿刺国产钛镍记忆合金网状内支架置入,治疗肝门区胆道恶性狭窄取得了较理想的疗效,现报告如下。
With the increase of the incidence of cholangiocarcinoma, the malignant stenosis of bile ducts is increasing. For those who are difficult to surgically cure and are not suitable for surgery, biliary stenting is a relatively new interventional treatment that can replace intraductal and external bile duct drainage. At present, there are two approaches for intracoronary stenting, namely endoscopic and percutaneous puncture. The former is due to a long path, especially for those with larger bile duct stenosis and stenosis angles in the hilar area. The operation is difficult and the latter is short. And feasible selective intubation, the success rate can be more than 90%. We have adopted percutaneous puncture of domestic titanium-nickel-memory alloy mesh stents to treat gallbladder malignant stenosis in the hilar region. The results are as follows:
