Abstract:
The blind insertion of the Veress needle and the first trocar may cause serious complications. Therefore, many surgeons perform a minilaparotomy to safely position the first trocar. However, especially in obese patients, the dissection may be difficult and time consuming. As an alternative, optical trocars can be safely positioned under direct visualization. We report on our experience with the Optiview trocar in 200 patients and describe our preferred insertion technique. In our opinion, optical trocars are safe and easy to handle, offering several advantages over the use of the Veress needle and the minilaparotomy.
