In this study, electrochemical burns of the esophagus from button-type alkaline batteries were demonstrated. A charged mercurial button-type battery was fixed in the esophagus of 11 dogs. After 2, 4, 8, 24, 48, or 72 hr, batteries and esophagus were removed and examined micro and macroscopically. In 3 dogs, a charged battery with double capsule and dummy battery were placed for 24 hr. At 8 hr after placement, the esophagus mucosa showed abrasion. The charged batteries produced superficial abrasion or necrosis under the muscular layer of the esophagus without any evidence of leakage of the battery content during 48 hr. Dummy batteries did not produce any pathological findings. This indicates that the corrosion was caused by flow of a direct 1.5 v current and not by outflow of the content or compression.
在本研究中，证实了纽扣型碱性电池导致的食管电化学灼伤。将一枚带电的汞纽扣型电池固定在11只狗的食管中。在2、4、8、24、48或72小时后，取出电池和食管并进行微观和宏观检查。在3只狗中，放置一枚带双胶囊的带电电池和一枚假电池24小时。放置8小时后，食管黏膜出现擦伤。带电电池在食管肌层下产生浅表擦伤或坏死，在48小时内没有任何电池内容物泄漏的迹象。假电池未产生任何病理结果。这表明腐蚀是由1.5伏直流电的流动引起的，而不是由内容物的流出或挤压引起的。
