With the improvement of people’s living standard, eating fish has become an indispensable part of everyday life, especially in coastal areas where fish products are abundant. Eating more fish naturally increases the chance of getting stuck by fish spikes. Most people who have experienced fish sticks will never forget the pain they cause, first of all, the pain at the site of the fish sticks, and then the difficulty in swallowing. These symptoms often vary greatly depending on the thickness, length, hardness and location of the injury. In general, thick, long and hard fish spikes cause more damage and more pain, while the opposite is less painful. The anatomical structure of the human digestive tract determines that there are some areas where foreign bodies are most likely to be lodged, and if we order them from superficial to deep, they are, in order, the tonsils, the root of the tongue, the epiglottis, the pear-shaped fossa, and the entrance to the esophagus. Smart readers will understand that the shallower the foreign body is, the easier it is to see and take out. Otherwise, it will take a lot of effort. In the clinic, we often encounter such patients, who do not seek medical attention first, but try to swallow it, and then try to bring it down with rice balls and vegetable balls if they cannot swallow it. It is true that this approach is mostly successful for small burrs, but it can be fatal for large, thick and long spines. It is important to highlight that the wall of the esophagus is thin, only 3-4 mm thick, and easily perforated. The second stenosis is where the aortic arch crosses, and once a sharp fish spike (or other foreign body) pierces the esophagus in this area, it is likely to pierce the aorta. Although it sounds sensational, there is a lesson in blood. It is definitely beneficial to understand that the above-mentioned reasoning can be prevented before it happens.
