Secondary esophageal perforation rupture of ascending aorta 16 day accidently-swallowing button battery in a young child: A case report of esophagial foreign body and mini review

INTRODUCTION AND IMPORTANCE: Foreign body ingestions often occur in children between the ages of six months and three years. Swallowing button battery can cause serious complications such as gastrointestinal mucosa tissue necrosis and esophageal perforation. Fatal secondary lesions after foreign body removal are rarely reported. CASE PRESENTATION: We reported a case of 18 months old boy who accidently swallowed a button battery (20 mm diameter, 3.2 mm height) which lodged in the esophagus for 3 days before removed by esophagoscope. Secondary esophageal perforation and rupture of ascending aorta resulted in death 13 days after the battery was removed. The autopsy confirmed the rupture and tissue necrosis of the esophagus and ascending aorta. CLINICAL DISCUSSION: The button battery incarcerated in the second stricture of the esophagus can cause serious complications and death even after removal due to battery-induced tissue erosion. Great attention should be closely paid to early endoscopic reinspection postoperatively and take comprehensive treatment to avoid similar death. CONCLUSION: When the incarceration of button batter occurs in the second stricture of esophagus, the possibility of esophageal perforation and the rupture of main artery should be considered. The comprehensive treatment after operation is as important as taking out the foreign bodies.
