Targeted tumor application method adopting endobronchial ultrasound

Abstract

The invention discloses a method for targeted application of ultrasound fiberoptic bronchoscopic tumor body, which comprises the following steps: firstly, local anesthesia with medication before operation, and the airway is explored according to a conventional fiberoptic bronchoscopy method to understand the location and growth of the lesion; Conventional fiberoptic bronchoscopic high-frequency electric snare and nitrogen sub-knife equipment are used to resect the tumor in the trachea; the conventional fiberoptic bronchoscope is withdrawn, and the ultrasonic bronchoscope is sent into the airway, and the ultrasonic probe detects the depth of tumor invasion into the trachea and the root and The relationship between the surrounding tissues; under the guidance of the ultrasound bronchoscope, the chemotherapy drugs cisplatin and cetuximab were injected at multiple points in the submucosal part of the tumor tissue; the ultrasound bronchoscope was withdrawn, and the conventional bronchoscope was sent into the airway again, And multi-point freezing treatment was given to the tumor site; after freezing treatment, dexamethasone and gentamicin were sprayed locally at the opening of the main bronchus on the side of the tumor lesion.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for targeted administration of tumors by fiberoptic ultrasound. Background technique [0002] Bronchial lung cancer is a malignant tumor originating from the bronchial mucosa or glands. Its morbidity and mortality rate ranks first among all malignant tumors. Smoking is the most important pathogenic factor of lung cancer. Lung cancer patients often have symptoms such as cough, hemoptysis, and weight loss. Timely examinations such as chest imaging and fiberoptic bronchoscopy can make the diagnosis of most patients. In terms of treatment plan selection, according to different tumor pathological types, stages, and molecular biological characteristics, combined with the actual situation of the patient, select the corresponding comprehensive treatment methods such as surgery, chemotherapy, radiotherapy, targeting, immunotherapy, and traditional Chinese medicine. Although the...
