Techniques available to accomplish this objective can generally be divided into closed and open categories. Specific choice depends on surgeon experience and preference as well as careful patient selection. The primary tools used to create pneumoperitoneum by the closed technique are the Veress needle and optical viewing trocar. The alternative “open” technique uses the Hasson trocar or hand port to provide initial access.
