OBJECTIVE
To explore the possibilities and efficiency of Sigma covered stents for the treatment of tracheoesophageal fistula (TEF).
METHODS
Between 2006 and 2009, 10 Sigma covered mental stents had been placed by guidance of bronchoscopy and/or fluoroscopy in 8 patients with 9 tracheoesophageal fistulas. Among them, 7 fistulas were caused by cancer and 2 by mechanical damage. Seven fistulas were located in lower part of trachea and 1 each in the middle and upper parts.
RESULTS
Six Y-shaped, 2 L-shaped and 2 I-shaped stents were placed respectively in 8 patients with 9 TEFs. All the TEFs were effectively sealed by the stents except for 1 massive lower and 1 upper fistulas. One mechanical fistula was cured within 1 year of stent placement. The mean survival period of all patients was 8 months.
CONCLUSION
By sealing the fistula with a Sigma covered stent, severe respiratory infection may be successfully controlled in patients with TEFs with a major improvement of quality of life.
目的
探讨西格玛覆膜支架治疗气管食管瘘（TEF）的可能性及疗效。
方法
2006年至2009年期间，在支气管镜和/或荧光镜引导下，为8例患有9处气管食管瘘的患者置入了10枚西格玛覆膜金属支架。其中，7处瘘由癌症引起，2处由机械损伤引起。7处瘘位于气管下部，中部和上部分别各有1处。
结果
8例患有9处气管食管瘘的患者分别置入了6枚Y形、2枚L形和2枚I形支架。除1处较大的下部瘘和1处上部瘘外，所有气管食管瘘均被支架有效封闭。1例机械性瘘在置入支架后1年内治愈。所有患者的平均生存期为8个月。
结论
通过使用西格玛覆膜支架封闭瘘口，气管食管瘘患者的严重呼吸道感染可得到成功控制，生活质量得到显著改善。
