Removal of foreign bodies: the flexible fiberoptic endoscope.
Three foreign bodies were successfully removed from the upper gastrointestinal tract with a fiberoptic endoscope. They included a food bolus lodged above an esophageal stricture, a metallic nebulizer tip impacted in the mid-esophagus, and a spoon lodged in the stomach. A razor blade could not be removed from the duodenum. Many foreign bodies, including large or elongated objects, can be removed from the upper gastrointestinal tract with flexible fiberoptic endoscopes.
