Fluorescein dye can aid in the localisation of chyle leak. Lymphatic drainage is to the chyle cistern. The lipids in the chyle are colloidally suspended in chylomicrons. These chylomicrons then pass into the lacteals, forming a milky substance known as chyle. Diagnosis of a chyle fistula may be accomplished by analysis of pleural/peritoneal fluid. The "Chyle", is the name of a sinkhole located northwest of Summit Lake. Up to three liters of chyle can easily drain into the pleural space daily. This causes the chyle to ooze extensively into the pleural cavity, leading to a chylothorax. The lymphatic vessels carry the chyle to the venous return of the systemic circulation. Chyle does not generally cause pleural inflammation or fibrosis. The enriched lymph originating in the lymphatics of the small intestine is called chyle. Chyle is then transported through the lymphatic system to the rest of the body. Chyle is rich in protein and white blood cells that are important in fighting infection.
