Laparoscopic entry techniques.

摘要

Laparoscopy is the method of visualization of the peritoneal cavity. It often involves intra-abdominal cannula insertion, insufflation with CO_2 to a standardized required pressure and visualization of intra-abdominal structures using camera and telescopes. It has been developed over many years from a predominately diagnostic role to an operative therapeutic treatment. This transition has been facilitated by the advent of finer, more complex and detailed visualization systems, manipulation aides and instruments. Compared to laparotomy, minimally invasive procedures such as laparoscopy have the advantage of reduced inpatient time and therefore morbidity, reduced pain and a quicker recovery time.
