Vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO), is a common condition characterized by breathlessness associated with inappropriate laryngeal narrowing. Important questions remain unresolved, and to improve collaboration and harmonization in the field, we convened an international Roundtable conference on VCD/ILO in Melbourne, Australia. The aims were to delineate a consistent approach to VCD/ILO diagnosis, appraise disease pathogenesis, outline current management and model(s) of care and identify key research questions. This report summarizes discussions, frames key questions and details recommendations. Participants discussed clinical, research and conceptual advances in the context of recent evidence. The condition presents in a heterogenous manner, and diagnosis is often delayed. Definitive diagnosis of VCD/ILO conventionally utilizes laryngoscopy demonstrating inspiratory vocal fold narrowing >50%. Computed tomography of the larynx is a new technology with potential for swift diagnosis that requires validation in clinical pathways. Disease pathogenesis and multimorbidity interactions are complex reflecting a multi-factorial, complex condition, with no single overarching disease mechanism. Currently there is no evidence-based standard of care since randomized trials for treatment are non-existent. Recent multidisciplinary models of care need to be clearly articulated and prospectively investigated. Patient impact and healthcare utilization can be formidable but have largely escaped inquiry and patient perspectives have not been explored. Roundtable participants expressed optimism as collective understanding of this complex condition evolves. The Melbourne VCD/ILO Roundtable 2022 identified clear priorities and future directions for this impactful condition.
声带功能障碍/可诱导性喉阻塞(VCD/ILO)是一种常见病症,其特征是呼吸困难伴发不适当的喉狭窄。仍有许多重要问题悬而未决,为了促进该领域的协作与协调,我们在澳大利亚墨尔本召开了一次 VCD/ILO 国际圆桌会议。会议旨在制定一致的 VCD/ILO 诊断方法,评估疾病发病机制,概述当前的管理模式,并确定关键的研究问题。本报告总结了讨论内容,提出了关键问题,并详细介绍了建议。与会者在讨论中结合最近的证据,探讨了临床、研究和概念方面的进展。该病症表现形式多样,且诊断常常被延误。VCD/ILO 的明确诊断通常需要借助喉镜检查,显示吸气时声带狭窄>50%。喉计算机断层扫描是一种具有快速诊断潜力的新技术,但需要在临床路径中进行验证。疾病的发病机制和多种合并症的相互作用非常复杂,反映出这是一种多因素、复杂的病症,没有单一的主导疾病机制。目前,由于缺乏治疗的随机试验,因此不存在基于证据的标准护理。最近的多学科护理模式需要明确阐述并进行前瞻性研究。患者的影响和医疗保健的利用可能是巨大的,但这些问题在很大程度上尚未得到研究,也没有探讨患者的观点。圆桌会议的参与者对这一复杂病症的集体认识不断深入表示乐观。2022 年墨尔本 VCD/ILO 圆桌会议为这一具有重大影响的病症确定了明确的优先事项和未来方向。
