A laparoscopy, also known as keyhole surgery, is a way to access the abdominal and pelvic cavities for surgical procedures using small surgical incisions.
It is done using long and thin telescopes with powerful optical systems, precise surgical instruments with small tips and energy sources that allow safe dissection of internal organs and sealing of blood vessels.
Most common gynaecological operations such as hysterectomies, removal of fibroids, removal of ovaries and ovarian cysts, to name a few, are now usually done via laparoscopy.
An important concept to understand is that a laparoscopy is not the operation itself. It is only the way to get access to the inside of the abdomen and pelvis to perform surgery.
How is a laparoscopy done?
A laparoscopy is done under general anaesthesia. It may require 1 to 4 surgical incisions of about 0.5 cm each. The first one is done inside the umbilicus. The camera is passed through this incision and gas is pumped inside the abdomen to distend it and create room for the instruments. Depending on the complexity of the surgery being done, up to three other incision are made on the sides. A hollow plastic cylinder, called a surgical port or trochar, is inserted in each of the incisions. Through those, instruments can be inserted and removed as required. There is a large variety of ports, instruments and accessories that can be used depending on the requirements of each case..
What are the benefits of a laparoscopy?
A laparoscopy provides better visualisation of the abdomen and pelvis than open surgery. The camera can get very close to all areas and magnify the image. The small surgical incisions mean less surgical trauma. The implications are: less pain after surgery, smaller scars, less time spent in hospital, quicker recovery, reduced use of pain killers, less bleeding and lower risk of infections. Laparoscopy is a very well established and safe mode of access to the abdominal cavity with clear advantages over laparotomy (open surgery).
Whenever possible, accessing the abdomen and pelvis via laparoscopy should be the preferred option.
