First Result of a Tailored Progressive Multistep Approach for the Treatment of Aorto-esophageal Fistulae
Background Aorto-esophageal fistulae (AEFs) are a rare but serious and life-threatening disease of the mediastinum. Especially, AEF in the presence of infected stent grafts, for example, after thoracic endovascular aortic repair (TEVAR) is only curable by a multistage interdisciplinary surgical approach. This study presents the results of our four-stage approach consisting of bridging TEVAR, esophagectomy, complete stent removal followed by total bovine tube aortic replacement (TBTAR), and finally esophageal reconstruction.
Methods A case series of four patients from our department receiving a four-stage treatment of AEF is presented in this study. Retrospective database analysis focusing on overall survival, duration of intensive care unit and total hospital stay until discharge, complications, surgical time frame, and completion of chosen surgical treatment course was performed.
Results Overall, four patients surgically treated for AEF since May 2015 were included. A 30-day mortality was 0%, and overall survival at 1 year was 75%. All patients survived more than 5 months and could be discharged after TEVAR and esophagectomy. TBTAR could be performed in two of four patients (50%). Esophageal reconstruction was completed in all patients. Average follow-up was 20.3 ± 1.7 months or until death.
Conclusion The acute management of AEF using this approach seems satisfactory, especially for reducing acute short-term mortality. Complete restoration of the circulatory system and digestive tract remains challenging and is associated with high morbidity. We support the application of bridging TEVAR with a staggered approach to further surgical treatment individually tailored to the patient.
