Lumpectomy (sometimes known as a tylectomy, partial mastectomy, breast segmental resection or breast wide local excision) is a surgical removal of a discrete portion or "lump" of breast tissue, usually in the treatment of a malignant tumor or breast cancer. [1]
It typically describes the removal of a tumor or mass and ancillary lymph nodes that may drain the mass, as in radical mastectomy. [2] It is opposed to for example palliative surgery which is intended for symptom relief rather than complete removal of cancer tissue.
A wide local excision of the breast aims to remove benign and malignant lesions while conserving the normal shape of the breast as much as possible. It is a form of breast-conserving surgery. A WLE can only be used for lesions up to 4 cm in diameter, as removal of any larger lesions could leave a visibly dented area in the breast.
The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) and early stage cervical cancer discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ). It is considered a type of conization. [1]
Vasectomy is the surgical occlusion of the vas deferens, tubes that connect to the male testes and transport sperm, a procedure for the purposes of sterilization in males. Vesiculectomy is the removal of all or part of the seminal vesicle. Vitrectomy is the removal of some or all of the vitreous humor from the eye.
Total mesorectal excision (TME) is a standard surgical technique for treatment of rectal cancer, first described in 1982 by Professor Bill Heald at the UK's Basingstoke District Hospital. [ 1 ] [ 2 ] It is a precise dissection of the mesorectal envelope comprising rectum containing the tumour together with all the surrounding fatty tissue and ...
A parotidectomy is the surgical excision (removal) of the parotid gland, the major and largest of the salivary glands.The procedure is most typically performed due to neoplasms [1] (tumors), which are growths of rapidly and abnormally dividing cells.
This type of procedure is typically elective and outcomes following the procedure are typically good. [9] The rate of cholecystectomies being performed on patients with cholecystitis has increased markedly since the first laparoscopic procedure was performed in 1985; jumping from 2.2% in 1996 to 31.4% in 2008.
