The milky fluid which travels in the lymphatic vessels draining the small intestine. It contains most of the products of digestion of the fat content of a meal, which are absorbed into the microscopic lacteals in the villi that project from the intestinal lining. Chyle is a particular type of lymph — the general term for fluid drained from body tissues; it flows into progressively larger channels to join lymph from other parts of the body in the thoracic duct in the chest, and thence reaches the bloodstream.

— Stuart Judge

See alimentary system; lymphatic system.

The milky fluid taken up by the lacteals from the intestine during digestion, consisting of lymph and triglyceride fat (chylomicrons) in a stable emulsion, and conveyed by the thoracic duct to empty into the venous system.

Chyle is a milky bodily fluid consisting of lymph and emulsified fats, or free fatty acids (FFAs). It is formed in the small intestine during digestion of fatty foods, and taken up by lymph vessels specifically known as lacteals. The relative low pressure of the lacteals allows large fatty acid molecules to diffuse into them, whereas the higher pressure in veins allows only smaller products of digestion, like amino acids and sugars, to diffuse into the blood directly.[1][2]

Pathology

A chyle fistula is a leakage of lymphatic fluid from the lymphatic vessels, typically accumulating in the thoracic or abdominal cavities. [3]

Treatment of chyle fistula: Intraoperative recognition of a thoracic duct injury is managed by ligation of the duct. This is because direct repair is impractical owing to the extreme friability of the thoracic duct.[clarification needed]
