应用Sigma覆膜支架治疗食管气管瘘22例临床分析

目的 探讨Sigma覆膜支架治疗食管气管瘘的优点和使用方法.方法 对采用Sigma支架治疗的22例食管气管痿患者的临床资料进行分析.其中,食管癌17例,食管良性病5例,病史4 d～2个月.放置1个气管支架5例,气管食管双支架15例,3个支架2例;直管形气管支架18例,钝角L形气管支架3例,Y形气管支架1例.支架置入分为介入法和内镜法两种.结果 22例成功放置41个支架,无手术死亡.除了1例良性患者迁延不愈、1年后行手术治疗,1例气管支架封堵不完全,再次放置食管支架外,其余均一次治疗成功,2～4 d后可正常经口进食.成功率91%(20/22),未完全成功率9%(2/22).结论 食管和(或)气管放置Sigma支架可有效封堵食管气管瘘,患者术后均可正常进食.此支架优点是可以回收并能有效防止继发食管气管瘘.

Clinical analysis for 22 cases of esophago-tracheal fistula treated with Sigma stent

Objective To evaluate the application of Sigma stent in treatment for esophagn-tracheal fistula. Methods Clinical data of 22 cases of esophago-tracheal fistula treated with Sigma stent were retrospectively analyzed, including 17 cases of esophageal cancer and 5 cases of benign esophageal diseases, with length of 4 days to 2 months. One single stent was placed in 5 cases, two stents ( both in trachea and esophagus each) in 15 cases, and three stents in 2 cases, and 18 eases with tube-type trachea stent, 3 with obtuse angle L-type and 1 with Y-type. Placement of stent was by interventional method or/and endoscopy. Results Forty-one stents were successfully placed in 22 patients with no death in the procedure. And, all patients with fistula were healed successfully and could have normal eating 2 to 4 days after operation, except 1 patient who received a tracheal stent inserted first, but an esophageal stent inserted again due to incomplete seal of the fistula and another benign case who received surgical operation 1 year after stent placement due to protracted unsealed fistula, with an overall cure rate of 91% (20/22). Conclusions Placement of Sigma stent in the esophagus or/and trachea could effectively heal esophago-tracheal fistula. All the patients can eat normally after the procedure. Stent can be recycled and formation of secondary esophago-traeheal fistula can be prevented effectively with such procedure.
