When examining patients with endoscopy, traditional methods often cause pain for the patient. During ENT endoscopy, the patient can be in a sitting or semi-recumbent position. The doctor inserts the ENT endoscope into the endoscope. The patient`s oral cavity, ear cavity, and nasal cavity should be inspected carefully. Because the medical endoscope has good illumination and high definition, the sinus mirror can be clearly seen to the depth, narrow, and not directly under the frontal mirror. Structures to look at, such as the uncinate process in the middle nasal passage, ethmoid vesicles, maxillary sinus opening, olfactory cleft, nasopharyngeal eustachian tube opening, adenoid tissue, etc. Endoscopy endoscopy is a technology that can be used for visual inspection and treatment with a speculum that can be sent into the human body cavity. Divided into two kinds of non-invasive and traumatic. The former refers to directly inserted into the endoscope to inspect the cavities communicating with the outside world (such as the digestive tract, respiratory tract, urinary tract, etc.); the latter is sent to the endoscope through an incision to inspect the closed body cavity (such as the chest, Abdominal cavity, joint cavity, etc.). The electronic camera uses microelectronic technology to take and develop images. Its appearance is the same as that of the fiber light guide endoscope. Connect the eyepieces of various endoscopes to the connector of the camera, and the images can be displayed on the TV screen for observation, and the effect is similar to that of an electronic endoscope. Endoscopes are divided into digestive tract, genitourinary tract, respiratory tract, body cavity and head organ speculum according to their purpose.

1. Irritating cough of unknown cause If it lasts for more than 10 days, or the throat has changed its characteristics, it is a signal to be vigilant. It can be a manifestation of some inflammation, or it may be an early symptom of lung cancer, but this symptom is often ignored by people. 2. Hemoptysis or sputum The lower respiratory tract is rich in blood vessels, and there are more opportunities for hemoptysis. People are more wary of a little blood. Studies have shown that bronchoscopy due to hemoptysis accounts for about half of the total number of people examined. The results of the examination confirm that about 2/3 are lung cancer. Lung cancer hemoptysis is characterized by small amount, freshness and persistence. 3. Atelectasis After the atelectasis is confirmed by X-ray fluoroscopy or photography, bronchoscopy should be done. According to statistics, bronchoscopy for atelectasis accounts for about 1/3 of the total number of people examined, of which lung cancer accounts for 2/3. Such a high positive rate is certainly an indication for this examination. 4. Hilar enlargement or spherical or block shadow It is often a change of mediastinal lymph node enlargement, and central lung cancer is often manifested by this. Bronchoscopy is common to squeeze deformation of the lumen or new organisms in the lumen. Tuberculous bronchial lymphadenitis also has similar changes. Bronchoscopy is a diagnostic method to obtain cytological or histological evidence. 5. Peripheral spherical or massive shadow Peripheral lesions are difficult to characterize. Although it is not easy to see the peripheral lung fields with bronchoscopy, after determining the lung segment, distant cytology smears also have a higher positive rate, which is more acceptable than percutaneous lung puncture or thoracotomy. 6. Localized lung stridor It is caused by stenosis of the tracheobronchial lumen. The occupying and squeezing of new organisms is the most common. Lung cancer and tuberculosis are the main reasons. 7. Recurrent pneumonia at fixed sites This may be because lung cancer has spread to lymphatic vessels, or it may be accompanied by infection. The clinical treatment effect is often more solid and not easy to subside than general inflammation. 8. Symptoms and signs suspected of being linked to bronchial disease 9. Positive exfoliated cells in sputum but negative lung x-ray 10. Routine examination before lung surgery Clarify the scope of resection and surgical procedures, and understand the condition of normal lung segments as a reference for surgical planning. 11. Postoperative lung cancer, radiotherapy, chemotherapy process or follow-up Bronchoscopy is an inspection method to observe the effect, determine the recurrence, and supplement the treatment. 12. Remove pus plugs, mucus plugs, pus and other bronchial obstructions, improve drainage, inject drugs to treat abscesses, and inject contrast media to confirm the diagnosis 13. Do lung biopsy, lung lavage, guide laser electrocautery to stop bleeding 14. Remove the bronchial foreign body About 98% of the bronchial foreign bodies can be removed from the bronchoscope. The larger ones can be removed by the hard bronchoscope. The fine foreign bodies that fall to the periphery can be removed by the soft fiber bronchoscope, or with X-ray.
