In recent years an increase in the incidence of esophageal injury due to battery ingestion by infants with miniaturization of batteries has been noted. A case of esophageal ulceration due to lithium battery ingestion is reported. Moreover, an experimental model of esophageal injury due to lithium battery ingestion was produced in dogs, and the tissue damage was evaluated histologically. When the battery was inserted and left in the esophagus for one hour, the structure of the esophagus was well preserved. Minor injury was histologically found in the group in which the battery was retained for two hours. Esophageal injury from the epithelium to the muscle layer was found when the battery was retained for four hours. On the basis of our experimental findings, early extraction within four hours is desirable in the case of an esophageal foreign body of electric battery.
近年来，随着电池小型化，婴儿吞食电池导致食管损伤的发生率有所增加。本文报道一例因吞食锂电池导致的食管溃疡病例。此外，还建立了狗吞食锂电池导致食管损伤的实验模型，并对组织损伤进行了组织学评估。当电池插入食管并留置1小时时，食管结构保存良好。留置2小时的组在组织学上发现有轻微损伤。当电池留置4小时时，发现食管从上皮到肌层均有损伤。基于我们的实验结果，对于食管内的电池异物，在4小时内尽早取出是可取的。
