Laparoscopist performance was assessed using a modified OSA-CNS. Two blinded raters independently scored surgical videos to evaluate inter-rater reliability and internal consistency. Technical errors and events were obtained from previous studies using the Generic Error Rating Tool. Modified OSA-CNS scores were compared using the Kruskal\u2013Wallis test. The associations of laparoscopist performance with errors, events, and procedure time were analyzed using surgeon-clustered linear regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Briefly, 25 unilateral procedures with 185 errors and 40 events were included. The median procedure time was 23.3 (20.3\u201329.4) min. The modified OSA-CNS demonstrated excellent inter-rater reliability (intraclass correlation coefficient = 0.96) and internal consistency (Cronbach\u2019s \u03b1 = 0.88\u20130.91). It distinguished performance across laparoscopists with differing experiences (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .0020).
