A retrospective analysis of 56 button (miniature) battery ingestions was conducted. This represents the largest series in the literature studying this problem. Impaction of these foreign bodies, most frequently in the esophagus (five cases), was a uniform predictor of severe morbidity. In the remaining 51 cases, the battery traversed the esophagus without incident; only four of these ingestions produced symptoms, and there was only one case with any severe complications. In 33 asymptomatic patients, the battery passed spontaneously through the gastrointestinal tract. Fourteen patients underwent endoscopic or operative procedures or both despite the absence of symptoms. Unanticipated mucosal erosions were noted in seven of these patients, although no symptoms or sequelae developed. Initial chest roentgenogram and observation for symptoms will detect ingestors at risk of complications. Operative or endoscopic intervention should be withheld in the absence of these clinical indicators. Button batteries can routinely be allowed to pass spontaneously.
对56例纽扣（微型）电池吞食病例进行了回顾性分析。这是文献中研究该问题的最大系列病例。这些异物嵌顿，最常见于食管（5例），是严重发病的一致预测因素。在其余51例中，电池顺利通过食管，这些吞食病例中只有4例出现症状，只有1例出现任何严重并发症。在33例无症状患者中，电池自行通过胃肠道。尽管没有症状，仍有14例患者接受了内镜或手术操作或两者皆有。在这些患者中有7例发现了意外的黏膜糜烂，尽管未出现症状或后遗症。最初的胸部X线检查和症状观察将发现有并发症风险的吞食者。在没有这些临床指标的情况下，应避免进行手术或内镜干预。纽扣电池通常可允许自行通过。
