Aortic injury caused by esophageal foreign body-case reports of 3 patients and literature review.

Objectives: Ingestion of a foreign body can cause different degrees of damage to esophagus, and several complications are potentially life-threatening if not properly handled. The aortic injury caused by a perforating esophageal foreign body is rare but lethal. The optimal management still remains controversial. The purpose of this report is to describe our experience in the management of the aortic injury caused by esophageal foreign body ingestion. Methods: Between January 2015 and December 2015, we retrospectively enrolled cases of esophageal perforation involving the aorta by foreign body. The general parameters, esophageal foreign body, types of aortic injury, treatment, and outcome were analyzed. Additionally, we reviewed the literature of the management of esophageal perforation involving the aorta caused by foreign bodies. The study was approved by the ethics committee of the First Affiliated Hospital, College of Medicine, Zhejiang University, and the need for informed consent was waived (Quick review 2019, No. 609). Results: Three cases of esophageal perforation involving the aorta by foreign body was selected in the study. Two male and 1 female patients (range, 51-58 years old) with the aorta involvement caused by a perforating foreign body in the esophagus in 3 forms were identified, including 1 patient with mycotic aortic pseudoaneurysm, 1 patient with aortoesophageal fistula and 1 patient with the aortic intramural hematoma. One patient died of the rupture of the pseudoaneurysm during the preparation of the surgery. The other 2 patients were cured with a multidisciplinary approach, which is an urgent thoracic endovascular aortic repair followed by mediastinal debridement/drainage or endoscopic retrieval. Two of 3 patients were survived until now. Conclusion: The management of the aortic injury caused by esophageal foreign body injury is challenging. Early diagnosis and multidisciplinary management is crucial.
