Abstract
Chylothorax after esophageal surgery is a rare complication but can lead to death in patients due to malnutrition, fluid imbalance, and immunodeficiency. Multiple treatment options exist for postoperative chylothorax, including conservative treatment, octreotide therapy, and interventions such as thoracic duct embolization and surgical ligation of the thoracic duct. We present a case of lymphatic leakage following laparoscopic esophagectomy for esophageal cancer, confirmed by lymphangiography. The patient underwent an intervention to embolize the thoracic duct under computed tomography after an initial failure under digital subtraction angiography (DSA). One week after the intervention, the patient's pleural fluid output gradually decreased, and the patient was discharged from the hospital. At a 7-month follow-up, the patient remained stable with no recurrence of lymphatic leakage.
