Abstract:
Objective To observe the value of ultrasound for diagnosing esophageal foreign body in children.Methods Ultrasonic manifestations of 45 children with esophageal foreign body were retrospectively analyzed,and the diagnostic value of ultrasound was evaluated.Results Among 45 cases,cervical esophageal foreign body was found in 40 cases(40/45,88.89%),while thoracic esophageal foreign body was detected in 5 cases(5/45,11.11%).Ultrasound correctly diagnosed 44 cases of esophageal foreign body,with an accuracy rate of 97.78%(44/45).Among different kinds of foreign bodies,fruit pits mainly presented as arc strong echogenicity accompanied by behind sound shadow,plastic stickers exhibited strong echogenicity with clear edges in the form of stripes,fish bones presented as irregular or slender strong echogenicity,button batteries demonstrated in arc/short strip strong echogenicity accompanied by sound shadows in the rear,while cooked albumen appeared as irregular chunks without echo,and the sarcocarp,toy parts and coins often presented as different shaped moderate/strong/mixed echogenicity,metallic foreign bodies with"comet tail"sign behind the strong echoes.Among 44 cases ultrasound correctly diagnosed esophageal foreign body,no abnormal changes of surrounding esophageal wall was found in 31 cases(31/44,70.45%),whereas mucosal necrosis injury and ulcer formation were detected in 7 cases(7/44,15.91%),inflammatory edema of esophageal wall were noticed in 3 cases(3/44,6.82%),and 3 cases(3/44,6.82%)were found with esophageal perforation.Conclusion Ultrasound was convenient and feasible for diagnosing esophageal foreign body in children with high accuracy.
