Evaluating the management timeline of tracheoesophageal fistulas secondary to button batteries: A systematic review

During the SARS-CoV-2 pandemic, the incidence of pediatric button battery (BB) ingestions has risen. Children have spent more time at home from school, while many parents try to balance working from home and childcare. Additionally, the amount of electronics powered by BB has increased. Tracheoesophageal fistula (TEF) secondary to a retained aerodigestive BB is a devastating development. Management is challenging, and the clinical timeline of watchful waiting versus surgical intervention for TEF is poorly defined in the literature. In accordance with PRISMA guidelines, databases searched include PubMed, Scopus, and CINAHL from database date of inception through August 13, 2021. All study designs were included, and no language, publication date, or other restrictions were applied. Case series and reports of TEFs secondary to BBs were included. Clinical risk factors and outcomes were compared between the spontaneous closure and surgical repair groups. A total of 79 studies with 105 total patients were included. Mortality was 11.4%. There were 23 (21.9%) TEFs that spontaneously closed and 71 (67.6%) that underwent surgical repair. Median time to spontaneous closure compared to surgical repair was significantly different (8.0 weeks [IQR 4.0–18.4] vs. 2.0 weeks [IQR 0.1–3.3], p
