Though complications of foreign bodies in the esophagus are rare, they are sometimes fatal due to injuries to the esopageal wall by sharp pieces of bone, metals, long-term lodgement of foreign bodies in the esophagus or a little inadvertence during diagnostic or therapeutic esophagoscopy on patients with esophageal disease. Therefore, failure to early diagnose and adequately treat the complications will lead to high morbidity and mortality. The authors have experienced 27 cases of complications of foreign bodies in the esophagus caused by foreign bodies themselves or inadvertence during esophagoscopy. So we report them with literature review.
