Management of chyle fistula utilizing thoracoscopic ligation of the thoracic duct.
OBJECTIVE
To document the treatment of refractory chyle leaks using thoracoscopic thoracic duct ligation and provide systematic guidelines to manage chyle leaks.


METHODS
The medical records of 2 patients with chyle leaks are reviewed, followed by a review of the literature on chyle leaks and their thoracoscopic management.


CONCLUSIONS
Initial treatment of chyle fistula is aimed at conservative medical management. Persistent high-output fistulas (>500 cm(3)) should be considered for neck reexploration as conservative management is likely to fail. Thoracoscopic thoracic duct ligation provides a safe and efficient means of treating chyle leaks refractory to repeated surgical and medical intervention. It should also be considered as a primary surgical intervention for patients with: (1) chyle output exceeding 500 cm(3)/day where prior intraoperative attempts at ligation have failed, (2) severe metabolic and nutritional complications, (3) coexisting chylothorax with respiratory compromise, and (4) low-output fistulas (<500 cm(3)/day) of long duration (>14 days).
