The full name of biopsy is in vivo histopathology examination, which is a professional technology. It is a method to remove diseased tissue from the patient's body surface, body or body cavity through forceps, and then carry out histopathological examination. Common biopsy practices are as follows:
1. Surgical biopsy: Usually under local anesthesia or general anesthesia, the diseased tissue is removed through surgery. This kind of trauma is larger but the sampling is accurate;
2. Endoscopic biopsy: It is to remove the diseased tissue under gastroscopy, colonoscopy, laryngoscope, bronchoscope or cystoscope. The advantages of endoscopic biopsy are small trauma and quick recovery, but the disadvantages are that it is not easy to take materials and the tissue is small, which has a certain impact on the diagnosis.
3. Needle biopsy: Needle biopsy is to locate and remove the local tissue under the guidance of B ultrasound or CT. This operation has little trauma and fast recovery, but it also has certain limitations, which has a certain test of the operator's skills.
Biopsies are mainly used to determine the nature and extent of lesions to guide clinical treatment and prognosis. According to the need of clinical diagnosis and treatment, different biopsy methods were adopted respectively.
