"New perspective of endoscopic grasping forceps" new technology of endoscopic foreign body removal: magnetic nasal strap assisted metal foreign body removal
Foreign body ingestion is a common clinical phenomenon and a common manifestation and indication of emergency endoscopic intervention. Especially in children, accidental ingestion of foreign bodies is extremely common, and some patients (self-harm tendency, intellectual disability, or combined mental illness) even have repeated and deliberate ingestion of foreign bodies. Clinically, about 20% of foreign body ingestion requires endoscopic intervention, and 5% requires surgical treatment. The shape and material of the ingested items are different, combined with the location of the foreign body, the patient's symptoms, the timing of intervention, and the possibility of adverse events, are all important factors that affect the success rate of the operation and require careful consideration. Patients who deliberately ingest foreign bodies usually choose sharper and sharper metal materials, including needles, batteries, magnets, etc. These foreign bodies are corrosive and may cause damage to the body, and the esophagus and stomach are easily damaged during the removal process. , Which greatly increases the difficulty of removing foreign bodies under the endoscope, and the risk of adverse events is as high as 35%. In order to improve the effectiveness of treatment, many devices, such as forceps, snares, biopsy forceps, net baskets, transparent caps, etc. have been tried to assist in mechanical removal of foreign bodies under endoscopic grasping forceps, but some tools require special materials to prepare and have certain limitations in operation , Is not widely recommended for clinical use.
Therefore, it is urgent to develop new technologies to improve the endoscopic removal efficiency of metal foreign bodies. The nasal band is a common and inexpensive item. Recently, clinical attempts have been made to remove metal foreign bodies through the use of a magnetic nasal band under the endoscope. This technology is considered to be a simple and effective treatment method, compared with traditional mechanical The removal method has more advantages and fewer adverse reactions.
