Endoscopic Treatment of Transesophageal Echocardiography-Induced Esophageal Perforation

Background: Perforation of the esophagus is the most severe complication of transesophageal echocardiography (TEE) and can lead to mediastinitis, pleural empyema, or peritonitis. Currently, the majority of patients receive operative treatment with only 6% treated endoscopically. We report our experience with endoscopic and conservative approaches. Methods: We retrospectively reviewed all patients treated for esophageal perforation and included all patients with perforation caused by TEE. All patients with perforation of the esophagus by TEE probe underwent conservative or endoscopic treatment, drainage of pleural and mediastinal retentions, and adjusted to antibiotic therapy. Results: From January 2004 to December 2014 a total of 109 patients were treated for esophageal perforation in our department. In 6 patients (5.5%) the perforation was caused by TEE. Location was cervical and midthoracic in 2 and 4 cases, respectively. All patients underwent successful endoscopic treatment and no further surgical procedure, such as esophageal suture or resection was necessary. The mean time between TEE and therapy of the perforation was 7.3 days. In all patients closure of the leakage could be achieved within 30 days. Mortality rate was 0%. Conclusions: Esophageal perforations caused by TEE are typically small, in the cervical and mid esophagus, and minimally contaminated. These are good prognostic factors for successful endoscopic treatment with preservation of the esophagus. Operative treatment should only be considered in cases of failed endoscopic treatment.
