Core Tip

Core tip: We report a case of esophageal cancer with a diverticulum in a patient who underwent endoscopic submucosal dissection (ESD). Although most esophageal diverticula can be diagnosed by endoscopy or computed tomography scans, the diverticulum in this case was not detected by these examinations before ESD, and led to perforation during the ESD procedure. This is a rare case; however, we should be aware that there could be diverticula without obvious depression.
