Esophagoscopy, flexible, transoral, is a medical procedure that involves the use of a flexible endoscope to examine the esophagus and remove foreign bodies that may be lodged within it. This procedure is performed by introducing the endoscope through the mouth and advancing it into the esophagus, allowing for direct visualization of the esophageal lumen. The flexible nature of the endoscope enables the physician to navigate the curves of the esophagus effectively. During the procedure, various techniques may be employed to remove foreign bodies, depending on their size, shape, and location. For instance, a balloon catheter can be utilized to extract smooth-edged foreign bodies, such as coins, by inflating the balloon beyond the foreign object and then withdrawing it to pull the object out. In cases where the foreign body is impacted, such as a piece of meat, forceps are used to grasp and remove the object. The procedure may also involve nudging impacted food into the stomach if removal is not feasible. Additionally, sharp foreign bodies, like tacks or razor blades, can be maneuvered into the lumen of the endoscope for safe extraction. After the foreign body is removed, the endoscope is reintroduced to re-examine the esophagus for any signs of perforation or injury, ensuring that the esophagus is intact and free from complications following the removal process.
