Esophagoscopy, flexible, transoral; with dilation of esophagus, by balloon or dilator, retrograde (includes fluoroscopic guidance, when performed)

Esophagoscopy, flexible, transoral, is a medical procedure that involves the use of a flexible endoscope to visualize the esophagus. This procedure is specifically designed for the dilation of the esophagus, which is often necessary when there is a stricture, or narrowing, of the esophagus. Strictures can occur due to various reasons, including complications from radiation therapy to the head and neck region or as a result of surgical procedures such as esophagectomy, where part of the esophagus is removed and reconstructed using gastric or colonic tissue. The retrograde approach refers to the method of accessing the esophagus from the stomach, which is particularly useful in cases where traditional access may be challenging. During the procedure, fluoroscopic guidance may be utilized to enhance visualization and ensure accurate placement of instruments. The dilation can be performed using either a balloon catheter or a series of dilators, allowing for effective widening of the narrowed area. This procedure not only aims to alleviate symptoms associated with esophageal strictures but also to ensure the integrity of the esophagus is maintained throughout the process.
