hemorrhoids cancer,[Yuncheng First Hospital Comprehensive Intervention] CT-guided needle biopsy preparation

    CT-guided needle biopsy technology (to clarify the type of pathology, and to point out the direction for choosing chemotherapeutics and treatment options)

    CT-guided puncture biopsy is a non-vascular intervention technique in which pathological specimens are obtained by percutaneous puncture of the lesions of interest (target lesions) in various parts of the body under the guidance of CT, and the pathological diagnosis is finally obtained. Because CT can clearly show the size, shape, location, necrotic cavity of the lesion, and can clearly show the good anatomical relationship with adjacent blood vessels, nerves, etc., the needle position, angle and depth can be accurately determined to avoid damage to blood vessels, nerves and spinal cord. , Thereby greatly improving the safety, success rate and pathological accuracy of interventional operations. The advantages are: simple method, less damage to tissues, less bleeding, safer, less chance of infection, it is performed under local anesthesia, and does not affect early treatment.

    Indications:

    1. The soft tissue or bony lesions in various parts of the body that are not diagnosed by clinical and various imaging examinations, especially those with highly suspected clinically malignant lesions, should be diagnosed by biopsy in time.

    2. Clinical and imaging examinations are diagnosed as malignant tumors, and the tissue-cytological diagnosis must be clear before chemotherapy or radiotherapy, molecular targeted drugs screened, or reference basis for surgery.

    3. The opinions of clinical and imaging examinations are inconsistent, it is difficult to decide the treatment plan and operation method in treatment, and the diagnosis of tissue characterization, classification and differentiation degree is required.

    4. All kinds of infectious and benign lesions (such as inflammation, abscess or tuberculosis, benign tumors, etc.), who need to identify the pathogen, do drug sensitivity test and qualitative diagnosis.

    5. Some parts are deep and have complex anatomical structures. For example, if the surgical biopsy of the neck, thoracic, and lumbar spine is more difficult, a needle biopsy can be used to confirm the diagnosis.

    Contraindications:

    1. Severe heart, lung, liver, kidney and other organ dysfunctions should be implemented with caution.

    2. Severe hypertension, diabetes, pulmonary heart disease, emphysema, or simultaneous systemic infection, high fever and local skin disease.

    3. Hemorrhagic diseases, such as arteriovenous vascular malformations, hemangioma, aneurysm (including aortic aneurysm), etc.

    4. Severe cachexia.

    Preoperative preparation:

    1. Make routine blood tests such as clotting time, prothrombin time, platelet count, red blood cell count, and white blood cell count.

    2. It is best to do a CT scan first, carefully analyze the chest CT image, and determine the location of the lesion; if the lesion is large or related to blood vessels, a CT enhanced scan should be performed, which is conducive to accurately formulating a needle biopsy plan before surgery. If the disease is in the neck, mediastinum, retroperitoneum, etc., CT scan should be routinely performed before surgery to fully understand the relationship between the disease and blood vessels, nerves, and heart.

    3. Those who cough can take antitussives, and those who are too nervous can take a small amount of sedatives.

    4. Fast 4-6 hours before puncture.
