METHOD FOR CERVICAL TRACHEA CICATRICAL STENOSIS OR LARYNGOTRACHEAL STENOSIS SURGICAL TREATMENT, AND PROBE FOR STENOSIS IMAGING DURING CERVICAL TRACHEA CICATRICAL STENOSIS OR LARYNGOTRACHEAL STENOSIS SURGICAL TREATMENT Russian patent published in 2017 - IPC A61B17/00 A61B1/00 

FIELD: medicine.

SUBSTANCE: surgical treatment of cicatricial stenosis includes its imaging and scar-altered tissue excision. At that, for stenosis area imaging in the trachea posterior wall, a probe is used. The probe consists of a flexible conductor with a closed distal end and an inner tube with successive LEDs on its distal end, installed in the conductor to move longitudinally. During operation, first, the closed end of the conductor, and then the inner tube are guided into the esophagus lumen through the mouth. Further, under visual control from the trachea lumen, transillumination is applied, LEDs are arranged on the stenosis level, and the stenosis area is determined within the boundaries of lower intensity of luminescence compared to the unaltered tracheal tissue. Scar-altered tissue excision in the posterior tracheal wall is performed under the control of transillumination, with visual inspection from the trachea lumen, maintaining saving LEDs arrangement in the stenosis zone until the luminescence intensity in this area is equal to the luminescence intensity of the unaltered tracheal tissue. Probe for surgical treatment of cicatricial stenosis comprises a flexible conductor in the form of an elongated tube made of transparent silicone with a closed distal end, an inner tube mounted in the flexible conductor with the possibility of longitudinal displacement and fixation, lighting means in the form of light-emitting diodes, successively arranged at the distal end of the inner tube at a distance of 3-6 mm from each other and means for electric current source connection in the form of copper wires with electrical insulation on the outer surface. Copper wires are arranged in the inner tube and connected to the switch, and the LEDs are connected in parallel.

EFFECT: maximum excision of the scar tissue in larynx and trachea in its posterior wall while maintaining the integrity of the esophagus anterior wall, allows to minimize the risk of recurrent laryngotracheal lumen restenosis, tracheoesophageal fistula formation, and to reduce the cannula carrying time due to application of the claimed probe and scar-altered tissue excision under transillumination control, until the luminescence intensity in the surgery area of equal to luminescence intensity of the unaltered tracheal tissue.
