This Society of Thoracic Surgeons General Thoracic Surgery Database analysis found that postoperative chylothorax risk increases with the extent of lymph-node dissection during pulmonary resection. Although uncommon, chylothorax was associated with substantial morbidity, including longer hospitalization and an increased need for reintervention, without a significant mortality effect. The findings emphasize that nodal staging must balance oncologic thoroughness against avoidable lymphatic injury.
For CTSNet’s audience, this large, real-world analysis is particularly relevant as surgeons refine nodal-management strategies for early-stage, small, less-solid, or low- fluorodeoxyglucose (FDG)-avid lung cancers. It supports thoughtful, risk-adapted lymph-node dissection—particularly around anatomically vulnerable mediastinal stations—rather than assuming that more extensive nodal clearance is uniformly beneficial.
