The real intraabdominal pressure during laparoscopy: Comparison of different insufflators

Within an error margin of <15% of the preset intraabdominal pressure setting, the insufflators evaluated can be considered pressure reliable. Although intraabdominal pressure peaks exceeding the nominal pressure temporarily reached up to 78.7% of the setting, no apparent complications were observed. Excessive pressure peaks seen in the previous reported laboratory model could not be confirmed during in vivo application.
