To determine the applicability of motion analysis parameters of intracorporeal knot tying in box trainers in experts as predictors of surgical outcome.
Consecutive series of 1534 advanced laparoscopic hysterectomies (Canadian Task Force classification II-2).
Time, path length, and motion in depth of a standardized intracorporeal knot-tying task were compared with mean risk-adjusted primary clinical outcomes for each participant.
Although a large variety in proficient knot tying and surgical skills factors was observed; after correction for patient mix in 50 expert surgeons, motion analysis of intracorporeal knot tying could not significantly determine surgical outcome skills in advanced laparoscopic surgery.
Levels of proficiency in advanced laparoscopic surgery cannot be appropriately determined using motion analysis in box trainers. Therefore, box trainer assessments do not adequately differentiate proficient from suboptimal clinical performance.
确定在箱式训练器中进行体内打结的运动分析参数在专家中作为手术结果预测指标的适用性。
连续系列的1534例高级腹腔镜子宫切除术（加拿大工作组分类II-2）。
将标准化体内打结任务的时间、路径长度和深度运动与每位参与者的平均风险调整后的主要临床结果进行比较。
尽管观察到熟练打结和手术技能因素存在很大差异；在对50名专家外科医生的患者组合进行校正后，体内打结的运动分析无法显著确定高级腹腔镜手术中的手术结果技能。
使用箱式训练器中的运动分析无法适当地确定高级腹腔镜手术的熟练程度。因此，箱式训练器评估不能充分区分熟练与次优的临床表现。
