The authors describe a simple method of removing objects such as bobby pins and straight pins from the upper gastrointestinal tract. A small but strong magnet such as the one used in a magnetic potholder is inserted in a nasogastric tube and passed through the mouth and nasopharynx under fluoroscopic control until it makes contact with the foreign body. The entire procedure takes only about two minutes and requires no special endoscopic skill.
作者描述了一种从上消化道取出如发夹和直针等物体的简单方法。将一个小而强的磁铁(如用于磁性锅垫的那种)插入鼻胃管,并在荧光镜控制下经口腔和鼻咽部推送,直至其与异物接触。整个操作过程仅需约两分钟,且不需要特殊的内镜技术。
