Esophageal diverticulum: New perspectives in the era of minimally invasive endoscopic treatment

Figure 3 Zenker’s diverticulum treated using endoscopic diverticulectomy. A: Zenker’s diverticulum (ZD, yellow triangle) visible on a barium swallow; B: On endoscopy, the ZD (yellow triangle) is easily visible and is bigger than the true esophageal lumen (black arrow); C: Endoscopic diverticulectomy is performed with a diverticuloscope (insert) straddled across the septum, with one flap inserted into the bottom of the ZD and the other in the esophageal lumen (black arrow) for a clear visualization of the septum and safe diverticulectomy[34]. ZD: Zenker’s diverticulum.
