Esophagoscopy, flexible, transoral, is a medical procedure that involves the use of a flexible endoscope to visualize the esophagus. This procedure is particularly important for diagnosing and treating conditions affecting the esophagus, such as strictures, which are areas of narrowing that can impede the passage of food. The flexible endoscope is introduced through the mouth and advanced into the esophagus, allowing the physician to directly observe the esophageal lining and any abnormalities present. In cases where strictures are identified, esophageal dilation may be performed to alleviate the narrowing. This can be achieved through various methods, including the insertion of a guide wire followed by the passage of dilators over the guide wire. The dilation process is crucial for treating strictures that may arise from several underlying conditions, including reflux esophagitis, which leads to inflammation and scarring; Schatzki's ring, a benign fibrous tissue formation; congenital esophageal atresia; or malignant diseases affecting the esophagus. The procedure is designed to restore normal esophageal function and improve the patient's ability to swallow.
