A Case of Pediatric Esophageal Pseudo-Diverticulum Caused by a Retained Foreign Body

Abstract

We report a case of esophageal pseudo-diverticulum. A 1-year 1-month old boy was admitted to a previous hospital with the complaints of postprandial vomiting and stridor at crying. Because an esophageal penetration was suspected by computed tomography, he was referred to our hospital. An emergency esophageal endoscopy revealed an esophageal pseudo-diverticulum caused by a piece of polyester film lodged in the mid-esophagus. His symptoms disappeared after the foreign body was removed. The esophageal diverticulum has markedly shrunk over 5 years. An esophageal foreign body risks perforation and it is necessary to remove it urgently. If there is no witness to foreign body ingestion and there are no notable symptoms, it may lodge in the esophagus for a long period and cause serious symptoms. It is necessary to add esophageal foreign body ingestion to the differential diagnosis when we observe chronic vomiting or stridor due to an unknown cause in children.
