METHOD FOR SELECTION OF TACTICS OF ENDOSCOPIC TREATMENT OF PATIENTS WITH TUMOUR STENOSES OF BIFURCATION OF TRACHEA AND BRONCHI OF 1-3 ORDER Russian patent published in 2025 - IPC A61B17/24 A61B1/267 A61F2/82 A61B17/94 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery. If the tumour is localized within the carina with involvement of one main bronchus, selective stenting of the main bronchus is performed under fluoroscopic control with a self-expanding metal coated stent provided with a perforation. If the tumour is localized within the carina with involvement of both main bronchi, bilateral stenting of the main bronchi is performed. If the tumour is localized in the main bronchus without involvement of the interlobar spur, selective stenting of the main bronchus is performed. Distal edge is inserted into one of the intact lobar bronchi. If the tumour is localized in the main bronchus without involvement of an interlobar spur, bilobate stenting of lobar bronchi is performed. Two metal self-expanding polymer-coated stents and holes are introduced into the area of stenosis with their subsequent simultaneous opening. In case of tumour localization in lobar bronchus without involvement of segmental bronchi, stenting of lobar bronchus is performed selectively. Distal edge of the stent is placed at the level of the fusion of the segmental bronchi. If the tumour is localized in the lobar bronchus with involvement of one or more segmental bronchi, stenting of the lobar bronchus is performed selectively. Distal edge of the stent is placed in one of the intact segmental bronchi. If the tumour is localized in a lobar bronchus with involvement of all segmental bronchi and an interlobar spur, stenting of the intact lobar bronchus is performed with overlapping of the involved bronchus. If the tumour is multifocally localized in different bronchi, stenting with two or more stents is performed.

EFFECT: method enables increasing the effectiveness of the endoscopic treatment of the patients with tumour stenosis of the tracheal and bronchial bifurcation of 1-3 order, reducing the time spent on the stent installation.
