In case of contraindications for surgical treatment, endoscopic techniques of recanalization of airways can be used. The most common are physical techniques such as argon plasma coagulation and cryodestruction. However, in this clinical observation of primary bronchus obturation by leiomyosarcoma metastasis we used endoloop resection.</p></abstract><trans-abstract xml:lang="ru"><p>Обтурация бронхиального дерева у онкологических пациентов, приводящая к затруднению дыхания, тахипноэ и асфиксии, чаще встречается при первичном злокачественном поражении дыхательных путей: трахеи, главных или долевых бронхов. При наличии противопоказаний к оперативному лечению у таких пациентов могут применяться эндоскопические методы реканализации просвета дыхательных путей. Чаще всего используются методики физического воздействия, такие как аргоноплазменная коагуляция или криодеструкция. Однако в данном клиническом наблюдении обтурации главного бронха метастазом лейомиосаркомы мы применили эндоскопическую петлевую резекцию.</p></trans-abstract><kwd-group xml:lang="en"><kwd>leiomyosarcoma of the retrocecal space</kwd><kwd>obturation of the bronchus</kwd><kwd>endoscopic recanalization of the bronchus</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лейомиосаркома забрюшинного пространства</kwd><kwd>обтурация бронха</kwd><kwd>эндоскопическая реканализация бронха</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
