Here is the treatment of bones that can’t be taken out by the Pentacenter: duck bones, chicken bones, perch snappers, silver carp, bighead carp bones and so on. Different animals have their own anatomical characteristics, so you need to know the type of bone and which area of the bone is in the bone before the operation, and at the same time, you need to use CT and other scanning means to make clear the morphology of the bones that are stuck in the throat or the esophagus, for example, whether they are stabbed in the side wall or across the esophagus. Gastroscopy is the first choice, really can not go to surgery; the most critical is the time, counting 6-8 hours from the beginning of the puncture is relatively safe, this time can be taken out in a timely manner is generally not a big problem; but more than 24 hours the wound will be eroded ulcers to the perforation, the relative difficulty of the treatment as well as complications will be much larger. So remind again, after the fish bone stuck, if their own methods are ineffective, immediately go to the hospital emergency department, the best not to swallow barium imaging, which will affect the subsequent endoscopic treatment may need; if the five doctors can not be removed, immediately shoot mediastinum scanning CT and immediately contact gastrointestinal endoscopy experts; if the endoscopy can not be removed, the gastroenterologists will be contacted by the follow-up thoracic surgery emergency surgery. The first two steps will resolve 99% of fish bone entrapments.
