Impact of Thoracic Duct Resection on Postoperative Body Composition Trajectory After Oesophagectomy: A Prospective Cohort Study

This is the largest study to date to assess longitudinal body composition changes after TDR using serial BIA. TDR was associated with a greater decline in sarcopenia-related indices, particularly within the first 3 months. These effects were transient, reversible and reproducible in early-stage patients. Our findings support the oncologic role of TDR while underscoring the importance of early nutritional and rehabilitative care.
