Chyle is lymph fluid of intestinal origin containing fat digestion products. Chylothorax is produced by leaks from the thoracic duct or from one of its collaterals subsequent to valve incompetence. These leaks may be due to trauma (post-surgical chylothorax, the most frequent) or to spontaneous rupture of a lymph vessel distended by chyle reflux, the thoracic duct itself being pathological. ⋯ Recently, treatment with octreotide has been found to be beneficial. Surgery consists in thoracic duct ligation or suture of leaking collaterals. In difficult cases, when the chyle leakage cannot be identified, pleurodesis is the only option.
