From the Research
Milky drainage from a wound is called chylous drainage or chyle, which occurs when lymphatic fluid containing fat leaks from damaged lymphatic vessels. This type of drainage appears white or milky due to its high triglyceride content and is most commonly seen after surgeries involving the thoracic duct, neck dissections, or abdominal procedures 1. The milky appearance results from chylomicrons (fat particles) suspended in the lymphatic fluid, which gives it its distinctive white color compared to other types of wound drainage like serous (clear) or purulent (pus-like) drainage.
Key Points to Consider
- Chylous drainage can be a sign of lymphatic vessel damage, which requires prompt medical attention to prevent further complications 2.
- Management of chylous drainage typically involves wound care, possible drainage procedures, dietary modifications (sometimes including medium-chain triglyceride diets or fat restriction), and in some cases, surgical repair of the damaged lymphatic vessels 3.
- Conservative treatments, such as total parenteral nutrition and somatostatin, can be effective in managing chylous fistula and reducing drainage volume 4, 5.
- Negative-pressure wound therapy (NPWT) has also been shown to be a promising treatment option for chylous fistula, promoting wound shrinkage and fluid removal 4.
Important Considerations for Treatment
- Early diagnosis and treatment are crucial to prevent complications and promote healing 1.
- A stepwise conservative approach, including dietary modifications and maintaining closed vacuum suction drainage, can be sufficient in most cases 3.
- Hematologic and serum values should be monitored carefully and corrected appropriately to prevent malnutrition and metabolic deterioration 1.
