Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.
目的： 分析儿童纽扣电池食管异物的临床特点及并发症。 方法： 回顾性分析2011年1月至2021年12月就诊于首都医科大学附属北京儿童医院耳鼻咽喉头颈外科的83例纽扣电池食管异物的患儿临床资料。其中男50例（60.2%），女33例（39.8%）。年龄为7月17天至9岁11个月，中位年龄18个月。记录并分析患儿食管内纽扣电池嵌顿时间、部位、临床特征、诊治情况、并发症及预后转归等相关临床资料。采用SPSS17.0软件进行统计学分析。 结果： <3岁患儿72例（86.7%）。吞入到就诊的时间1 h至2个月，中位时间8 h。在首诊于我院的63例患儿中，常见临床症状包括恶心、呕吐32例（50.8%），吞咽困难31例（49.2%），流涎11例（17.5%），发热10例（15.9%）。83例患儿有73例术前确诊检查完整，其中55例（75.3%）通过X线片明确诊断。56例（76.7%）异物嵌顿于食管上1/3。72例（86.7%）通过硬质食管镜取出。23例（27.7%）患儿出现严重并发症，包括气管食管瘘15例（65.2%），声带麻痹8例（34.8%），穿孔3例（13.0%），纵隔炎3例（13.0%），出血3例（13.0%），食管周围脓肿1例（4.3%）。严重并发症组在异物暴露时间、监护人对异物吞入不明确性方面有明显差异（P<0.05）。2例死亡（2.4%），分别因动脉食管瘘出血和气管食管瘘治疗过程中支架移位导致的呼吸衰竭死亡。 结论： 儿童纽扣电池意外摄入可危及生命，多发生于3岁以内儿童。非特异性的临床表现和不明确的异物摄入史，往往造成严重并发症。胸部正侧位X线片检查为首选。气管食管瘘是最常见的严重并发症。.
