Benign central airway obstruction (BCAO) related strictures include post- intubation tracheal stenosis, post- tracheostomy tracheal stenosis, post- surgical or anastomotic stenosis, stenosis related to inflammatory disorders or infectious disorders, chemical injury or post radiotherapy. Techniques and thresholds for airway stenting for each of these unique conditions vary significantly across centres due to lack of guidance. The management of the airway stents once placed due to scarcity of data also has a similar knowledge void. This document aims to address these knowledge gaps by addressing relevant questions related to airway stenting in BCAO. A multidisciplinary, international group of 20 experts from 19 institutions across 12 countries with extensive experience in airway stenting in BCAO was convened as part of this guideline document through the World Association of Bronchology and Interventional Pulmonology (WABIP). A literature search was performed for reports addressing eight clinically relevant PICO questions. Recommendations addressing these questions were formulated using a systematic process involving the evaluation of published evidence, supplemented with expert experience when necessary. The panel participated in the development of the final recommendations using a modified Delphi technique.

背景：良性中央气道阻塞（BCAO）相关狭窄包括：插管后气管狭窄、气管切开后气管狭窄、手术后或吻合口狭窄、炎症性疾病或感染性疾病相关狭窄、化学损伤或放疗后狭窄。由于缺乏指导性文件，针对这些不同情况的支架置入技术和阈值在各中心间存在显著差异。同样，由于数据匮乏，气道支架置入后的管理也缺乏共识。本文档旨在通过解决与BCAO气道支架置入相关的关键问题，以填补这些知识空白。

方法：作为本指南文件的一部分，世界支气管镜及介入肺脏病学协会（WABIP）召集了一个由来自12个国家、19个机构的20位专家组成的多学科国际专家组，这些专家在BCAO气道支架置入方面拥有丰富经验。针对八个具有临床意义的PICO问题，我们进行了文献检索。回答这些问题的推荐意见通过一个系统性流程制定，该流程包括评估已发表证据，必要时辅以专家经验。专家组采用改良德尔菲法参与最终推荐意见的制定。
