Caudal tracheal stent migration can be potentially life threatening by causing distal luminal obstruction. We present a rare double hitch stitch procedure (for prevention of migration of tracheal stent), which is an external fixation technique in a case of tracheoesophageal fistula with tracheal and esophageal self-expandable metallic stent (SEMS). A 50-year-old male patient who presented with cough and dyspnea was a known case of carcinoma of the esophagus with esophageal stent in situ. Computed tomography (CT) scan showed tracheoesophageal fistula with esophageal stent (esophageal SEMS) migrating into the trachea. Tracheal stenting was done with SEMS. Patient was followed up after 1 month with recurrent complaints of cough on deglutition. On follow-up bronchoscopy, migration of stent was observed. A rare procedure of double hitch stitch was performed with fixation of the tracheal stent (tracheal SEMS) using a percutaneous anchoring stitch, embedded in the subcutaneous tissue. Follow-up bronchoscopy after 1 month of the procedure showed no migration of stent. For the treatment of large tracheoesophageal fistula, stenting of both the trachea and the esophagus along with the double hitch stitch proved to be lifesaving. Stent migration prevention using “double hitch-stitch” is simple, safe, and successful, without any complications.

双钩针法是一种在气管食管瘘中固定气管支架的新技术：一例报告

尾气管支架迁移可能引起远端管腔阻塞，从而可能危及生命。我们提出了一种罕见的双结缝合程序（用于防止气管支架迁移），这是在气管食管瘘合并气管和食管自膨胀金属支架（SEMS）的情况下的外固定技术。一名患有咳嗽和呼吸困难的50岁男性患者是食管癌原位食管癌的已知病例。计算机断层扫描（CT）扫描显示气管食管瘘与食管支架（食管SEMS）移入气管。气管支架置入术是通过SEMS完成的。1个月后对患者进行了随访，发现其反复出现咳嗽。在后续的支气管镜检查中，观察到支架的迁移。使用嵌入皮下组织的经皮锚固针固定气管支架（气管SEMS），进行罕见的双钩针缝合手术。手术1个月后进行的后续支气管镜检查未发现支架移位。对于大口气管食管瘘的治疗，气管和食管的支架置入术以及双钩结被证明是可以挽救生命的。使用“双结针”预防支架移位简单，安全且成功，没有任何并发​​症。事实证明，气管和食道的支架置入术与双钩结缝合法是可以挽救生命的。使用“双结针”预防支架移位简单，安全且成功，没有任何并发​​症。事实证明，气管和食道的支架置入术与双钩结缝合法是可以挽救生命的。使用“双结针”预防支架移位简单，安全且成功，没有任何并发​​症。
