Thoracic duct injuries are very rare due to its protected location. Duct is most often injured in polytraumas and during operations in his vicinity. Treatment is primarily conservative, based on a low-fat diet or parenteral nutrition and adequate chest drainage. If the conservative management fails, a surgical duct ligation via thoracotomy, or more conveniently thoracoscopic approach, is necessary. The presented case reports describe the surgical treatment of isolated injury of the thoracic duct via thoracoscopic approach.
