[Use of hemostatic clips for endoscopic hemostasis and closure of an esophageal laceration caused by a fish bone]. 
An 82-year-old woman was admitted to our hospital because of hematemesis.  She had had a feeling of a foreign substance in her throat for one week after having eaten fish.  On admission she had a fever of 38 degrees C, Hb of 5.8 g/dl, CRP level of 8.8 mg/dl, and bilateral pleural effusions.  Endoscopy revealed a deep longitudinal laceration with active bleeding in the esophagus that also caused mediastinitis.  Endoscopic hemostasis and closure of the laceration was done with hemostatic clips.  The esophageal injury seemed to have been caused by a fish bone.  After the treatments described here were carried out, the patient's condition rapidly improved.
