Fluorescence-Guided Thoracic Duct Dissection in Robotic en Bloc Esophagectomy.

En bloc resection of the thoracic duct compartment enhances adequate lymph node removal and may improve oncologic outcomes in esophagectomy for malignant esophageal diseases. However, it also increases the risk of postoperative chylothorax, with a reported incidence of 5% to 20%. This report describes a technique that facilitates intraoperative identification of the thoracic duct, as well as proximal and distal ligation, during robot-assisted esophagectomy by lymphangiography-guided injection of indocyanine green in the right groin in a patient in the left lateral position. This approach can be swiftly applied at any time during any thoracoscopic procedure using the lateral position when visualization of the thoracic duct anatomy is needed.
