[The aspiration pneumoperitoneum]

To date the pneumoperitoneum has been passively created by instrumentally monitored introduction of a gas, such as carbon dioxide gas. The abdominal cavity expander ACE developed already in 1991 produces an active pneumoperitoneum by suctioning air into the abdominal cavity; this is achieved by a modified and automated form of the ACE. A modified myoma drill elevates the abdominal wall for primary aspiration of air into the abdominal cavity by means of a Veress needle.
