What is LESS Surgery?
LESS stands for laparoendoscopic (lap•a•ro•en•do•scop•ic) single-site surgery, a modern, advanced approach for a variety of abdominal surgeries.
LESS is a form of laparoscopic surgery. Laparoscopic surgery, also called minimally invasive surgery, is when an operation is performed through 3-5 small cuts (incisions) in the abdomen as opposed to one large incision (see diagram below).
What’s different about LESS compared with other laparoscopic techniques is that the entire surgery is completed through just one small cut (incision) in the bellybutton, referred to as the umbilicus. The incision measures about ½ inch in length - smaller than a dime - leaving behind a scar that is virtually unnoticeable since it’s hidden in the natural contours of the bellybutton.
In gynecology, the LESS technique is commonly used for removal of:
- uterus (hysterectomy);
- ovaries (oopherectomy);
- fibroid tumors from the uterus (myomectomy);
- female sterilization such as tubal ligations; and,
- some early stage cancers.
