The patient underwent transbronchial needle knife electrocautery for precise scar tissue dissection, followed by sequential cryoablation to suppress granulomatous proliferation and balloon dilation for airway remodeling. After five interventional bronchoscopic procedures, complete luminal patency was achieved, with no recurrence observed during 8-month follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Through this case demonstration and literature review, we highlight the clinical value of combined bronchoscopic techniques (high-frequency electrocautery, cryotherapy, and balloon dilation) in managing stenosing active tuberculosis and preventing complete bronchial occlusion, providing clinicians with a minimally invasive therapeutic alternative.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2025.1642456","type":"journal-article","created":{"date-parts":[[2025,11,12]],"date-time":"2025-11-12T05:19:35Z","timestamp":1762924775000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic treatment of stenosing active tuberculosis to prevent complete bronchial occlusion: a case report and literature review"],"prefix":"10.3389","volume":"12","author":[{"given":"Kunying","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenjing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xia","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taomei","family":"Lian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"768","DOI":"10.3760\/cma.j.cn112147-20220120-00062","article-title":"Relationship between etiology and morphological classification of benign central airway stenosis and its prognosis","volume":"45","author":"Fang","year":"2022","journal-title":"Zhonghua jie he he hu xi za zhi"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"2001","DOI":"10.1007\/s00405-025-09230-1","article-title":"Patient-centred outcome following endoscopic management of benign central airway obstruction","volume":"282","author":"B\u00f8gh","year":"2025","journal-title":"Eur Arch Otorrinolaringol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"e31354","DOI":"10.1097\/MD.0000000000031354","article-title":"Treatment of scarring central airway stenosis with pirfenidone: case report","volume":"101","author":"Li","year":"2022","journal-title":"Medicine (Baltimore)"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"983","DOI":"10.1510\/icvts.2009.213215","article-title":"Urgent segmental resection as the primary strategy in management of benign tracheal stenosis.
