A 59-year-old patient presented with recurrent dysphagia 7 months after successful insertion of an esophageal covered metal stent (Choo-Stent; M.I.Tech Co., Ltd., Seoul, Korea). The stent had been inserted with palliative intent because of an obstructive T4 esophageal squamous cell cancer that was penetrating into the (already stented) trachea. After the esophageal stenting and subsequent chemotherapy the patient had initially made a very good recovery.

Endoscopy now showed that the esophageal stent was in a horizontal position and occluded with food particles ([Fig. 1] and 2). When the proximal end of the stent was grasped, it proved, surprisingly, to have broken into five fragments, which were removed without problems ([Fig. 3]). Once the fragments were removed, the esophageal passage was free. No further intervention was necessary, and to date the patient has not complained again of recurrent dysphagia. Repeat endoscopy 2 months later showed complete tumor remission.
