[edit on Wikidata] A chylothorax (or chyle leak) is a type of pleural effusion. It results from lymph formed in the digestive system called chyle accumulating in the pleural cavity due to either disruption or obstruction of the thoracic duct. In people on a normal diet, this effusion can be identified by its turbid, milky white appearance, since chyle contains high levels of triglycerides.
A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving sampling of cells or tissues for examination.It is the medical removal of tissue from a living subject to determine the presence or extent of a disease.he tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy.
A biopsy is the removal of a small piece of tissue for laboratory examination. There are several different types of biopsies. A needle biopsy is called a percutaneous biopsy. It removes tissue using a needle attached to a hollow tube called a syringe. The needle is passed several times through the tissue being examined. The doctor uses the needle to remove the tissue sample. Needle biopsies are often done using CT scan or ultrasound. These imaging tools help guide the doctor to the right area. An open biopsy is surgery that uses local or general anesthesia. This means you are relaxed (sedated) or asleep and pain-free during the procedure. It is done in a hospital operating room. The surgeon makes a cut into the affected area, and the tissue is removed.
