How serious is a chyle leak?
Chyle leaks are a rare but potentially fatal complication of head and neck surgery carrying an incidence as high as 8.3%. The development of a chyle leak carries significant morbidity ranging from delayed wound healing to oropharyngeal fistulas.
How do you repair a leaky chyle?
Octreotide therapy has been shown to be successful in high-volume leaks, with reported success in a 2300-mL chyle leak that persisted after 8 days of MCT diet then resolved 6 days after initiation of octreotide therapy with no adverse events.
What is a chyle leak after surgery?
Chyle leak formation is an uncommon but serious sequela of head and neck surgery when the thoracic duct is inadvertently injured, particularly with the resection of malignancy low in the neck. The thoracic duct is the primary structure that returns lymph and chyle from the entire left and right lower half of the body.
How long does it take for chyle leak to heal?
As part of your medical treatment for a chyle leak, you may need to follow a high protein, very low fat diet for a short period of time, around 3 weeks or less. When you eat less fat, your body makes less chyle and the leak is able to heal. The goal is to eat and drink as little fat as you can.
Why does chyle leak happen?
How is chyle leak diagnosis?
To confirm the diagnosis, ascitic or pleural fluid is assayed. The presence of chylomicrons and a triglyceride level higher than 110 mg/dL confirm the diagnosis of a chylous leak. The presence of chyle may be confirmed in the laboratory by measuring fat and protein content, pH, and specific gravity.
What causes a chyle leak?
Approximately 60% of chyle leaks are due to lymphoma; 25% due to trauma (iatrogenic or penetrating); other causes make up the remaining 15% of cases (2). The incidence of chyle leaks varies depending on the underlying cause.
What is Chyle fistula?
Chyle fistula is defined as a leakage of lymphatic fluid from the lymphatic vessels, typically accumulating in the thoracic or abdominal cavities but occasionally manifesting as an external fistula. It is a rare but potentially devastating and morbid condition.
Can a chyle leak be repaired?
Injuries to the cisterna chyli or thoracic duct should be repaired by means of lateral closure with a 6-0 to 8-0 polypropylene suture. If this is unsuccessful, proximal suture ligation of the cisterna chyli and thoracic duct may be implemented.

What is the difference between chyle and Chyme?

What is the best treatment for chyle leakage in thoracic ducts?

What are the possible complications of chyle fistula?
If left untreated, chyle fistulas can be fatal, with patients dying from severe fluid and electrolyte abnormalities, malnutrition, and overwhelming infections, including peritonitis and empyema. Iatrogenic complications also can occur, [ 33] as well as complications from shunt placement, including DIC, shunt failure, and fluid overload.
