Cardiac tamponade in a long-term survival esophageal cancer patient after esophageal bypass and chemoradiotherapy: a case report

Esophageal bypass surgery is an effective treatment strategy for esophageal cancer with esophago-tracheobronchial fistula. We herein report an esophageal cancer patient with esophago-pulmonary fistula who achieved a long-term survival but died suddenly because of cardiac tamponade. A 70-year-old male patient with esophago-pulmonary fistula due to esophageal tumor invasion underwent definitive chemoradiotherapy as the initial treatment. Esophageal bypass surgery followed by additional chemotherapy was performed, and the patient survived for a long time. Four years and six months later, a small abscess in an esophago-pulmonary fistula was visualized on computed tomography. One month later, he suffered suddenly severe dyspnea and died. An autopsy suggested that the direct cause of death had been cardiac tamponade due to atrio-pericardial fistula. Definitive therapy for esophageal cancer with fistula after esophageal bypass is an effective treatment, but close special attention must be paid to the possibility of irradiation-related late toxicity.
