Laparoscopic surgery

Laparoscopic surgery, also called keyhole surgery (when natural body openings are not used), bandaid surgery, or minimally invasive surgery (MIS), is a surgical technique. Medically, laparoscopic surgery refers only to operations within the abdomen or pelvic cavity. Laparoscopic surgery belongs to the field of endoscopy.

A laparoscope contains a fibre optic system to illuminate the operative site, a lens system to view the operative site that is usually connected to a video camera (videoscopic procedures using a laparoscope or endoscope) and a channel to allow access for intervention using long, thin instruments. Through small incisions a surgeon can introduce additional instruments through side ports. Rather than a 20 cm cut as in traditional cholecystectomy, two or five cuts of 5-15 mm will be sufficient to perform a laparoscopic removal of a gall bladder. The abdomen is usually insufflated with carbon dioxide gas to create a working and viewing space.
This approach is intended to minimise operative blood loss and post-operative pain, and speeds up recovery times. However, the restricted vision, difficult handling of the instruments (hand-eye coordination), lack of tactile perception and the limited working area can increase the possibility of damage to surrounding organs and vessels, either accidentally or through the difficulty of procedures.
