For bronchoscopy alone, recovery is possible in 4-5 hours. In addition, if endobronchial endoscopy-related operations are performed, it may take 3-5 days of rest to recover. Bronchoscopy is a common surgical procedure in respiratory and thoracic surgery, which can not only routinely understand the airway condition, but also perform related procedures, such as pathological biopsy, hemostasis, alveolar lavage, brushing, tumor removal, stenting, etc. Generally, simple bronchial examination is done without special discomfort, without damage to the mucosa, and with about 4-5 hours of rest for complete recovery. Some patients need to undergo bronchial endoscopy for biopsy or treatment, and the mucosa may be broken to different degrees, and they need to rest for half an hour after the procedure and closely observe whether there are complications such as hemoptysis and dyspnea. It may usually take about 3-5 days of rest before full recovery. For bronchoscopy alone, the results are usually available on the same day or on the 2nd day. If tissue is also taken for pathology, the results may take longer, about 1 week, and bacterial culture may take more time.
