The distance from the subumbilical port to the caudal aspect of the gallbladder was measured as a proxy for intra\u2010abdominal working length (IWL). Prestretching was performed by insufflating to an intra\u2010abdominal pressure (IAP) of 10\u2009mmHg for 3\u2009min. The abdomen was desufflated back to 6\u2009mmHg for the remainder of the procedure. A computed volumetric value utilizing skin measurements and IWL was used as a proxy for intra\u2010abdominal working space (IWS). Percentage changes in IWL and IWS were compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Increasing the IAP from 6 to 10\u2009mmHg increased the IWL by 7% (IQR 9.5%) and the IWS by 10.4% (IQR 13.8%) (<jats:italic>p<\/jats:italic> = .004 and .005, respectively). Returning to 6\u2009mmHg after prestretching resulted in a median increase in IWL of 4.4% (IQR 5.7%) and IWS of 6.9% (IQR 5.4%) compared with the initial 6\u2009mmHg IAP measurements (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001 for both).
