How do you get pneumoperitoneum?
To establish the pneumoperitoneum, access to the peritoneal cavity can be gained through minilaparotomy and insertion of a laparoscopic trocar or Hasson trocar. Alternatively, an optical trocar can be blindly inserted into the peritoneal cavity, or a Verres needle may be inserted through the abdominal midline.
