biopsy

 [bi´op-se]
removal and examination, usually microscopic, of tissue from the living body, often to determine whether a tumor is malignant or benign; biopsies are also done for diagnosis of disease processes such as infections.
Technique for endometrial biopsy. Longitudinal strips of the endometrium are sampled using an in-and-out and rotational motion. From Rakel, 2000.
aspiration biopsy one in which tissue is obtained by application of suction through a needle attached to a syringe.
brush biopsy one in which the sample is obtained by a brush with stiff bristles introduced through an endoscope, such as for a tissue sample from an inaccessible place such as the renal pelvis or bronchus.
chorionic villus biopsy chorionic villus sampling.
cone biopsy one in which an inverted cone of tissue is excised, as from the uterine cervix.
endoscopic biopsy removal of tissue by instruments inserted through an endoscope.
excisional biopsy removal of biopsy tissue by surgical cutting, such as a lumpectomy.
fine-needle aspiration biopsy aspiration biopsy using a fine needle. For superficial tissue such as the thyroid, breast, or prostate the needle is unguided, but for deep tissue it must be guided radiologically.
incisional biopsy biopsy of a selected portion of a lesion.
needle biopsy (percutaneous biopsy) one in which tissue is obtained by insertion through the skin of a special type of needle (see biopsy needle).
punch biopsy one in which tissue is obtained by a punch-type instrument.
sentinel node biopsy biopsy of a sentinel node (the first lymph node to receive lymphatic drainage from a malignant tumor). It is identified as follows: a dye and a radioactive substance are injected into the body, which causes certain nodes to “light up” like a sentinel, indicating that they are the most appropriate ones for examination. They are detected by both the light created by the dye and the radioactive substance that is monitored by a gamma camera. If the sentinel nodes do not contain malignant cells, this usually eliminates the need for removal of more distal nodes. Called also intraoperative lymphatic mapping.
shave biopsy biopsy of a skin lesion by excising it with a cut parallel to the surface of the surrounding skin.
stereotactic biopsy biopsy of the brain using a stereotactic technique to locate the biopsy site. This can be done as a minimally invasive surgery technique. The patient's head is held in a special rigid frame so that a probe can be directed into the brain through a small hole in the skull.
sternal biopsy biopsy of bone marrow of the sternum removed by puncture or trephining; see also sternal puncture.

cone biopsy

Conization The surgical excision of the cone-shaped uterine cervix, which encompasses the ectocervix and endocervical portion of the uterine cervix; it is performed as definitive therapy for CIN 1 to 3, and has been used for circumscribed carcinoma in situ, microinvasive SCC, and rarely, condylomas, confined to the cervix, while preserving the uterus Complications Bleeding, infection, cervical stenosis, cervical incompetence. See Cervix, CIN, HPV, HSIL, LSIL. Cf LEEP.

cone biopsy

The removal of a cone-shaped segment of tissue from the inside of the neck of the womb to provide material for positive microscopic diagnosis. This is done under general anaesthesia when a cervical smear test suggests that cancer may be present.

If you have early cervical cancer, it may be possible for you to be treated with a cone biopsy, a surgical procedure that allows most women to remain fertile.
Cone biopsy can also rarely lead to cervical stenosis followed by hematometra formation.
A cone biopsy is performed if one or more smear tests have come back with an abnormal result, indicating very early precancerous or cancerous changes.
The clinician decided to perform cone biopsy because of the repeated abnormal cytologic and DNA-based results.
Ceri underwent further tests, including a cone biopsy, which removes tissue from the cervix.
The council worker had an operation called a cone biopsy to remove the abnormal area but doctors were still concerned and recommended a further operation to remove more tissue, but that was cancer free.
Two other methods - cone biopsy and diathermy - also led to a chance of premature births.
Himes, of the department of obstetrics and gynecology, Magee--Womens Hospital, Pittsburgh, identified 1,080 women who had become pregnant after undergoing a colposcopic biopsy, a loop electrosurgical excision procedure, or a cold knife cone biopsy Overall, cervical conization was not associated with an increased rate of preterm birth, which occurred in 12.7% of the cohort.

The investigators excluded 246 of 740 women who had a positive screening test because of various reasons, including symptomatic bacterial vaginosis; age <16 years; multiple gestations; had or needed cervical cerclage or cone biopsy; demonstration of a cervical, uterine, or fetal anomaly; diabetes mellitus, hypertension, or collagen vascular disease.
The study provides scarce data on the natural history of CIN 2 and 3, which usually gets treated promptly by ablation, loop electrical excisional procedure, or cone biopsy. Not all CIN lesions progress, however, so the ability to predict which ones will regress could help avoid unnecessary treatment and prevent related complications such as cervical stenosis, cervical incompetence, infection, and bleeding.
Q AFTER an abnormal cervical smear test, I have been told I need a cone biopsy as I have early cervical cancer.
