Esophagoscopy, flexible, transoral; with placement of endoscopic stent (includes pre- and post-dilation and guide wire passage, when performed)

AI EXPLANATION: Esophageal stent placement is a procedure in which a doctor inserts a thin, flexible tube with a camera through the mouth and into the swallowing tube, known as the esophagus. A small, expandable hollow tube called a stent is guided into position and opened to keep a narrowed or blocked section of the esophagus open. The procedure may also include gently widening the area with a small balloon or dilator before or after the stent is set in place.
