On November 20, 2012, the patient came to our outpatient clinic with a chest CT: soft tissue density shadow in the middle and lower lobe bronchi of the right lung, and further bronchoscopy was recommended. Combined with his history of choking and coughing, he was considered to have a high probability of foreign body and was admitted to the hospital. Chest CT: there must be something strange in the right middle bronchus! A closer look at the elderly man, 83 years old, was still in good condition with occasional coughing and chest discomfort. However, he was too old for general anesthesia, so we explained the procedure in detail before the operation and hoped that the old man would cooperate. After the old man removed all his dentures, we found that the old man was really quite old (note to colleagues who have fake things, the truth is sometimes a bit ugly after the removal of all the fake things!) . Give the old man this kind of operation, there is a little bit of panic in mind. After the pharynx is fully anesthetized, that is, carefully into the bronchoscopy, and indeed in the right middle bronchial mouth to see the culprit —– choking into the fava beans. However, it took a lot of effort to catch the culprit, because the bean was smooth all over, the small biopsy forceps at the beginning could not hold it, and only a small amount of the edge could be taken out, and the big guy still had to slip off, finally with the great assistance of Mr. Xu in the tracheoscopy room, three biopsy forceps were changed, and finally the culprit was taken out with foreign body forceps. The old man is also really strong, tracheoscope six in and six out, there are foreign bodies in the trachea harassment, the old man persevered, of course, we are also careful together with colleagues around the advice, finally in everyone’s cheer the culprit removed, put in the hands of the old man, at his disposal! Found the culprit! Catch the culprit! The truth about the culprit a lung can breathe freely! By the way, remind everyone to eat fava beans can be careful in the future!
