Cervical conization refers to an excision of a cone-shaped portion of tissue from the mucous membrane of the cervix. Conization is used for diagnostic purposes as part of a biopsy and for therapeutic purposes to remove pre-cancerous cells (cervical intraepithelial neoplasia) or early stage cervical cancer. [1]
It has been in use since the 1970s, after its invention by Dr. Sheldon Weinstein. [2] LEEP has many advantages including low cost and a high success rate. [3] The procedure can be done in an office setting and usually only requires a local anesthetic, though sometimes IV sedation or a general anesthetic is used. [4]
Vacuum-assisted breast biopsy (VABB) is a more recent version of core needle biopsy using a vacuum technique to assist the collection of the tissue sample. Similarly to core needle biopsy, the needle has a lateral ("from the side") opening and can be rotated, allowing multiple samples to be collected through a single skin incision.
I was surprised when the site of my benign breast biopsy (a procedure in which a sample of breast tissue is removed to be tested for cancer), in February, 2023, turned all sorts of colors and ...
Correlation between biopsy and final pathology is improved between MRI-guided biopsy as compared to TRUS. [14] In the fusion MRI-US prostate biopsy, a prostate MRI is performed before biopsy and then, at the time of biopsy, the MRI images are fused to the ultrasound images to guide the urologist to the suspicious targets. Fusion MRI-US biopsies ...
A stereotactic biopsy may be used, with x-ray guidance, for performing a fine needle aspiration for cytology and needle core biopsy to evaluate a breast lesion. However, that type of biopsy is also sometimes performed without any imaging guidance, [2] and typically, stereotactic guidance is used for core biopsies or vacuum-assisted mammotomy. [3]
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
This study suggests for women with cervical insufficiency due to prior cone biopsy, cerclage is not superior to no intervention. [9] As cerclage can induce preterm contractions without preventing premature delivery, [ 10 ] makes the recommendation that it be used sparingly in women with a history of conization .
