Endoscopic retrieval of a capsule endoscope from a Zenker's diverticulum.

We report a case of a capsule endoscope lodged within a Zenker's diverticulum. The capsule was safely removed endoscopically. Safe re-insertion of the capsule was achieved using an overtube placed with a Savary dilator. While capsule endoscopy should be avoided in patients with large esophageal diverticula or dysphagia, this method may be used to deliver the capsule beyond the esophagus, allowing completion of the capsule endoscopy study.
