The authors report two cases of accidental swallowing of sealed drug packages (press through pack). In the first case the pack passed into the stomach but acute mediastinitis developed subsequently. In the second case the foreign body was removed under esophagoscopy without causing complications. The authors warned of an increasing incidence of such foreign bodies in the esophagus and discussed the importance of early diagnosis and prevention of such accidents.
