AbstractA 75-year-old male received neoadjuvant chemotherapy for locally advanced squamous cell carcinoma of the mid-thoracic esophagus, followed by right transthoracic esophagectomy with extended mediastinal lymphadenectomy. Cardiac tamponade developed on postoperative Days 1 and 13, for which emergency ultrasound-guided drainage was required. Pericardial drainage fluid became chylous after administration of polymeric formula. A computed tomography scan demonstrated the presence of a retrocardiac fluid collection, encompassed by the left pulmonary vein and left atrium, descending aorta and vertebral column. Based on these findings, the diagnosis of chylopericardial tamponade communicating with a posterior mediastinal chylocele was made. The ligation of the thoracic duct was successfully performed via the left-sided thoracoscopic approach on postoperative Day 20 and the clinical course after the second operation was uneventful. The possible mechanisms of this exceptionally rare complication after esophagectomy were discussed.
