Laparoscopy is a procedure to look inside your abdomen by using a laparoscope. A laparoscope is like a thin telescope with a light source. It is used to light up and magnify the structures inside the abdomen. A laparoscope is passed into the abdomen through a small incision (cut) in the skin. A laparoscopy may be done to find the cause of symptoms such as abdominal pain, pelvic pain, or swelling of the abdomen or pelvic region.
