Vacuum-supported endoscopic access.

The rapid increase in the number of endoscopic operations performed has resulted in a corresponding rise in the incidence of severe complications. This issue has generated widespread concern at recent congresses. It is now indisputable that safer access to the abdominal cavity is required. We have developed a technique of vacuum-supported visual access which allows the surgeon to anticipate dangerous sites of access and avoid injuries to internal organs or retroperitoneal blood vessels. The procedure has two major advantages: Firstly, a pre-peritoneal approach allows the surgeon to visualise the structures behind the peritoneum, and secondly, puncture of the insufflation-needle is facilitated and the depth of insertion is minimised. The underlying principle is to use negative pressure to elevate the peritoneum. Using this approach, the principles of open surgery are adhered to during abdominal access, thereby avoiding visceral injury.
