Life we often encounter fish spines, meat bones, dentures, etc. stuck in the esophagus or children accidentally swallowed foreign objects (coins, hairpin, etc.) events, especially in recent years, theft, robbery, drug abuse and other types of cases are on the rise, in order to escape the culpability of the more extreme behavior, in which swallowing a foreign body is a more common means of foreign objects are often scissors, steel nails, chopsticks, a variety of razor blades, keys, toothbrushes, lighters, eyeglasses frame These foreign objects are often scissors, steel nails, chopsticks, blades, keys, toothbrushes, lighters, eyeglass frames, etc., and are medically referred to as upper gastrointestinal foreign bodies. Before the development of endoscopic examination and treatment, the traditional treatment method is to remove the foreign body by emergency surgical dissection or open thoracic surgery, or to take certain foods to promote the natural expulsion of foreign bodies, but the above methods are dangerous, with many complications and pain for the patients, especially when taking drugs to promote the excretion of foreign bodies, which leads to the embeddedness of the foreign body in the small intestine, which is even more dangerous. With the progress of endoscopic technology and the popularization of equipment, endoscopic gastrointestinal foreign body removal has formed a mature treatment technology, most of the gastrointestinal foreign bodies can be safely removed by endoscopy. Numerous cases have proved that endoscopic foreign body removal is safe, effective, simple, with fewer complications, and can reduce the patient’s pain and medical costs. Therefore, when there is no contraindication to gastroscopy, endoscopic treatment should be preferred for upper gastrointestinal foreign bodies. Li Jun, Department of Gastroenterology, The Second Affiliated Hospital of Kunming Medical University Metallic foreign bodies can be identified through X-ray filming of the location, size, shape of the foreign body, to understand whether there is a cavity perforation; non-metallic foreign bodies need to be directly examined under the endoscopy, generally not barium meal examination. Because barium can affect the field of view under the gastroscope, it is difficult to distinguish the foreign body, and barium is easy to block the hole of the gastroscope, delaying the time to take the foreign body. Fasting should be at least 4-6 hours before endoscopic foreign body removal. For those who have already eaten and have to perform emergency foreign body removal surgery, patients should be told to cooperate well and minimize vomiting to prevent vomiting and aspiration. After the removal of the foreign body, if there is no abnormality, you can eat normally. If observation is needed, the endoscopist will explain the precautions, such as paying attention to the presence of severe pain in the chest and abdomen, vomiting blood and other symptoms. If there is mucosal damage, give acid-suppressing and mucosal protective agents; if perforation is suspected, fast and stay in the hospital for close observation, and give antibiotics at the same time. Finally, we also want to remind everyone, eat to chew slowly; eat to reduce or avoid talking, pay attention to prevent rough foreign body damage to the digestive tract. If you accidentally swallow a foreign body, don’t swallow it, and go to the hospital in the shortest possible time to avoid foreign body damage to the digestive tract, resulting in gastrointestinal bleeding, perforation, or even injuring the airway and aorta and endangering your life.
