Abstract：
BACKGROUND: A straight silicone stent can be used to treat proximal benign tracheal stenosis in non-surgical candidates. However, stent migration is a common complication when placed at a particular location and can lead to major complications. This case series of laryngotracheal stenosis reports a fixation method for straight silicone stents in the subglottic trachea (Stage 3 of the McCaffrey classification).
METHODS: The medical charts of these patients scheduled for straight silicone stent placement with suture fixation between 2014 and 2020 at the CHU UCL Namur Hospital (Belgium) were retrospectively reviewed. The procedure was performed using a rigid bronchoscope. Details of the procedure were obtained from medical records.
RESULTS: This case series included six patients (males: 4, females: 2). The median patient age was 59 years. Two suture fixations were placed following previous silicone stent migration episodes, whereas the others were placed proactively to avoid this risk. All fixations were performed by the device Freka® Pexact II ENFIt®, originally developed for gastropexy in endoscopic gastrostomy. The sutures were subcutaneously buried.
CONCLUSIONS: During the 6-month follow-up period, complications such as fixation issues and stent migration were reported despite the off-label use of the treatment. The straight silicone stent fixation technique used in this case series was simple and effective for securing the stent in upper benign tracheal stenosis.

摘要：
背景：直硅胶支架可用于治疗非手术候选者的近端良性气管狭窄。然而,当放置在特定位置时，支架迁移是一种常见的并发症，并可能导致严重的并发症。此例喉气管狭窄系列报告了声门下气管中直硅胶支架的固定方法（McCaffrey分类的第3阶段）。
方法：回顾性分析了2014年至2020年在CHUUCLNamur医院（比利时）进行缝合固定的这些患者的病历。该程序使用刚性支气管镜进行。该程序的细节是从医疗记录中获得的。
结果：本病例系列包括6名患者（男性：4名，女性：2名）。患者年龄中位数为59岁。先前的硅胶支架迁移事件后放置了两个缝线固定，而其他人则被主动放置以避免这种风险。所有固定均由Freka®PexactIIENFIt®装置进行,最初开发用于内窥镜胃造口术中的胃切除术。缝合线皮下埋藏。
结论：在6个月的随访期间，尽管有标示外使用治疗,但仍报告了固定问题和支架移位等并发症.在这种情况下系列中使用的直硅胶支架固定技术对于固定上段良性气管狭窄中的支架简单有效。
