Salvage esophagectomy combined with partial aortic wall resection following thoracic endovascular aortic repair

摘要

Objective Definitive chemoradiotherapy is useful for locally advanced esophageal cancer. However, salvage esophagectomy is required when residual or recurrent tumor is evident after chemoradiotherapy. We performed salvage esophagectomy combined with partial aortic wall resection after thoracic endovascular aortic repair for aortic invasion, and we evaluated the results. Methods Four patients underwent esophagectomy combined with aortic wall resection after thoracic endovascular aortic repair because the lesion was diagnosed as stage T4b. We evaluated short-term outcomes, including duration of thoracic surgery, blood loss, duration of intubation, intensive care unit stay, and postoperative morbidity, as well as survival after salvage surgery. Results Lesions were resected with no intraoperative procedural adverse events. Mean thoracic operation time was 444?min, and mean thoracic blood loss was 506?g. In all patients, complete resection of the lesion was possible with no intraoperative adverse events. All patients were extubated on postoperative day 0, and all were discharged from the intensive care unit on postoperative day 1. One patient experienced grade II wound pain (bilateral chest pain), and another patient experienced difficult sputum expectoration (grade IIIA). The mean follow-up time was 19.8?months, and two patients were alive with no disease recurrence at the time of this report. However, the remaining two patients had died secondary to lymph node metastasis. Conclusions Salvage esophagectomy combined with partial aortic wall resection after thoracic endovascular aortic repair provides acceptable short-term outcomes. Future studies are needed to evaluate long-term survival and patient selection criteria.
