How to do lymph biopsy needle

There are generally two ways of lymph node biopsy: one is surgical resection and the other is lymph node puncture.

Surgical resection is the most direct method, and it has the highest positive rate. This method is the first choice. If there are disadvantages, sometimes the location of the lymph nodes will be deeper, and the operation will have a difficulty or risk, such as bleeding during the operation or infection after surgery.

Secondly, lymph node puncture is mainly done under the guidance of b-ultrasound. Generally, our thick needle is used for puncture. The fine needle is rarely used. Sometimes the specimen is insufficient, and then the correct diagnosis cannot be obtained. The advantages are that the complications are small and the risk of bleeding is small. Generally, this method is only used when the operation is difficult or high risk.
