Battery exposures were more common in males (59%) and young children. For ingestions, batteries were most often located in the stomach (43%). Mucosal damage (46%) and oesophageal stricture (10%) were the most common complications. Most (60%) children were asymptomatic at presentation. When symptoms were present, vomiting (26%) and dysphagia (18%) were the most common. Duration of ingestion to removal increased the likelihood of any complication; OR 3.71 (95% CI 1.11 to 12.42) for \u226510 hours and 5.12 (95% CI 1.79 to 14.67) for \u226512 hours. Battery diameter \u226520 mm was associated with any complication OR 4.34 (95% CI 1.16 to 16.27) and oesophageal location OR 18.66 (95% CI 6.99 to 49.82). Death was associated with oesophageal impaction OR 15.52 (95% CI 2.40 to 100.27). For insertions, nasal septal perforation was the most common complication (13%).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Interpretation<\/jats:title>\n                  <jats:p>Button batteries are a potentially fatal domestic hazard particularly for young children.
