Trepanobiopsy is a method of extracting a piece of bone marrow from a person without violating its integrity, with the aim of conducting a histological analysis.

Such a procedure allows the doctor to determine if there are changes in the bone marrow and to identify a number of diseases: erythremia, leukemia, osteomyelosclerosis, and others.

In addition, this method allows you to extract a sufficient amount of material that can not be done during puncture. For puncture usually use special needles, they are also called trepan.

Trepanobiopsy is of two types: bone marrow and breast. In the first case, this procedure remains the most informative, since the fragment for analysis does not change its structure during the fence. The needle for the operation is small, only 2 mm.

To get to the ilium scallop, where the material is taken from, a puncture is made.

The whole procedure takes a few minutes. It is performed under local anesthesia. There are no consequences after it, so there is no need to stay in a medical institution after manipulations.

Breast trepanobiopsy is the most accurate way to determine whether there are cancer cells in the patient’s body or not. The accuracy of this method is more than 90%.

If there is a cyst in the place of education, where the material for analysis comes from, a trephine biopsy will help get rid of it. To do this, experts remove the fluid and burn down the walls of the cyst.

The procedure takes no more than 20 minutes. The study is also conducted under local anesthesia using special spring needles. The most pleasant bonus from such manipulation is that there is no need to stitch it. Scars after trepanobiopsy of the breast do not remain.

When should trepanobiopsy be performed

Trepanobiopsy is not necessary in all cases of the disease. It is used to determine splenomegaly of unknown origin, chronic myeloproliferative diseases, aplastic anemia, and bone marrow damage.

Doctors resort to this procedure when an ordinary biopsy was unsuccessful.

As for contraindications, there are several of them:

  • the procedure should not be performed in patients with allergy to anesthesia;
  • the tumor is not detected by the ultrasound in the patient;
  • the presence of acute infectious diseases;
  • poor blood clotting;
  • epilepsy;
  • diseases of the respiratory system.

The procedure for trepanobiopsy

Before the procedure, the patient must pass the necessary tests and must do a chest X-ray. The procedure for trepanobiopsy is performed by a doctor. Preparation of the instrument and the surgical field produces a nurse. Puncture do in the scallop of the Ilium. The needle is constructed in such a way that, while rotating, it cuts out a column of bone and bone marrow tissue. This allows you to make the procedure faster and secure the patient.

After that, the material is taken for research. Next - remove the tool, and the material for analysis is sent for study. Results are expected no earlier than in two weeks. Thanks to this method, it is possible to accurately determine the presence of serious diseases or abnormalities in a patient.

Complications after surgery

Any surgical intervention is always a risk. And do not forget about it, even when trepanobiopsy. The most important indicator is the health of the patient. The most common complications after the procedure are bleeding and infection of the body.

After surgery, there may also be consequences:

  1. Infection of the site of trepanobiopsy;
  2. Blood infections;
  3. High level of osteoporosis;
  4. Violation of the cardiovascular system.

In order to protect themselves, patients who take blood thinning drugs at the time of the collection, doctors advise that they be abandoned for a while. After trepanobiopsy in humans, there may be complications such as chills, fever, pain at the puncture site, bleeding or redness, nausea and vomiting, joint pain, fatigue, shortness of breath, chest pain and cough.

In this case, you must immediately contact your doctor. Usually, all non-dangerous symptoms disappear on the second day after the procedure.

Postoperative period

After trepanobiopsy doctors recommend that you stop taking a bath for a day. In addition, it is strictly forbidden to drink alcohol. For any use of drugs, you should consult with your doctor.

In the event that manipulations were carried out on the mammary gland, experts recommend not to lift weights for 2-3 days. Due to local anesthesia, patients do not experience pain, they are most likely uncomfortable and unpleasant during the procedure.

The study provides an opportunity to study the structure of the seized material, the composition of cells and characteristics of blood vessels. When a doctor performs trepanobiopsy, he is guided by the following principles: benefit, safety and painlessness.

Trepanobiopsy spend many years. Therefore, do not worry about the technique of the manipulation. Thanks to the accumulated experience, she worked to the smallest detail.
