Esophagoscopy, rigid, transoral, is a medical procedure that involves the use of a rigid endoscope to visualize and treat conditions affecting the esophagus. This procedure is particularly focused on addressing strictures, which are areas of narrowing within the esophagus that can impede the passage of food and liquids. The rigid endoscope is inserted through the mouth and advanced into the esophagus, allowing the physician to directly observe the affected area. A guide wire is then introduced through the endoscope, serving as a pathway for subsequent dilation. Dilation is performed using a series of rigid tubes that progressively increase in diameter, which are passed over the guide wire to widen the narrowed segment of the esophagus. This technique is essential for treating strictures that may arise from various underlying conditions, including reflux esophagitis, which leads to inflammation and scarring; Schatzki's ring, a benign fibrous tissue formation; congenital esophageal atresia; or malignancies affecting the esophagus. After the dilation process, the physician inspects the dilated area with the endoscope to confirm the success of the procedure and to check for any potential injuries that may have occurred during the intervention.
