Metal stents have been advocated to manage complicated tracheal stenosis.
The purpose of this investigation is to review the effectiveness of endoscopic placement of tracheal expandable metal stents for complicated tracheal stenosis.
The charts of 6 patients who have undergone placement of metal expandable stents between 1998 and 2000 were reviewed.
Initially, all patients enjoyed immediate palliation of symptomatic tracheal stenosis. Eventually, 4 patients developed significant granulation tissue and/or recurrent stenosis, requiring intervention within 6 months after placement of the stent. One patient required the removal of the stent and placement of a T-tube silicone stent.
Metal stents provide temporary palliation for tracheal stenosis. Metal stents, however, are associated with a high incidence of obstruction with granulation tissue. Their use should be limited to a select group of patients with a short life expectancy (because of other comorbidities) or patients who are not good candidates for reconstructive surgery and/or who refuse or cannot tolerate a tracheotomy.
金属支架已被提倡用于治疗复杂性气管狭窄。
本研究旨在回顾内镜下置入可扩张金属支架治疗复杂性气管狭窄的有效性。
回顾了1998年至2000年间6例行金属可扩张支架置入术患者的病历。
最初,所有患者的症状性气管狭窄均立即得到缓解。最终,4例患者出现明显的肉芽组织和/或复发性狭窄,需要在支架置入后6个月内进行干预。1例患者需要取出支架并置入T形硅胶支架。
金属支架可为气管狭窄提供临时缓解。然而,金属支架与肉芽组织阻塞的高发生率相关。其应用应限于预期寿命较短(由于其他合并症)的特定患者群体,或不适合进行重建手术和/或拒绝或不能耐受气管切开术的患者。
