To investigate how visuospatial abilities develop and influence intraoperative laparoscopic performance during surgical residency training programmes.
Laparoscopic surgery is a challenging technique to acquire and master. Visuospatial ability is an important attribute but most prior research have predominantly explored the influence of visuospatial abilities in lab-based settings and/or among inexperienced surgeons. Little is known about the impact of visuospatial profiles on actual laparoscopic performance and its role in shaping competency.
A longitudinal observational cohort study using a pair-matched design over 27 months. At baseline, visuospatial profiles of 43 laparoscopic surgeons of all expertise levels and 19 control subjects were compared. The development of visuospatial abilities and their association with intraoperative performance of 18 residency surgeons were monitored during the course of their laparoscopic training.
Laparoscopic surgeons significantly outperformed the control group on the measure of spatial visualisation (U = 273.0, p = 0.03, η2 = 0.3). Spatial visualisation was found to be a significant predictor of laparoscopic expertise (R = 0.70, F (1.60) = 6.788, p = 0.01) and improved with laparoscopic training (B = 4.01, SE = 1.83, p = 0.02, 95% CI [0.40, 7.63]). From month 6 to 18, a strong positive correlation between spatial visualisation and intraoperative depth perception (r = 0.67, p < 0.01), bimanual dexterity (r = 0.60, p < 0.01), autonomy (r = 0.78, p < 0.01) and the total score (r = 0.70, p < 0.01) were observed but a strong relationship remained only with autonomy (r = 0.89, p < 0.01) and total score (r = 0.80, p < 0.01) at 18 months.
In this longitudinal cohort study, visuospatial abilities associate with laparoscopic skills and improve with training. Spatial visualisation may be characteristic of laparoscopic expertise as it has clear association with competency development during laparoscopy residency training programme.
探讨在外科住院医师培训计划中，视空间能力如何发展并影响术中腹腔镜操作。
腹腔镜手术是一项具有挑战性的技术，需要掌握。视空间能力是一个重要的属性，但大多数先前的研究主要在实验室环境中探索了视空间能力的影响，以及在缺乏经验的外科医生中的影响。对于视空间特征对实际腹腔镜操作的影响及其在塑造能力方面的作用知之甚少。
这是一项使用配对设计的 27 个月的纵向观察队列研究。在基线时，比较了所有专业水平的 43 名腹腔镜外科医生和 19 名对照组的视空间特征。在腹腔镜培训过程中，监测了 18 名住院医师的视空间能力发展及其与术中表现的关系。
腹腔镜外科医生在空间可视化测量上明显优于对照组（U=273.0，p=0.03，η2=0.3）。空间可视化被发现是腹腔镜专业技能的一个重要预测指标（R=0.70，F（1.60）=6.788，p=0.01），并随着腹腔镜培训而提高（B=4.01，SE=1.83，p=0.02，95%CI[0.40，7.63]）。从第 6 个月到第 18 个月，空间可视化与术中深度知觉（r=0.67，p<0.01）、双手灵巧性（r=0.60，p<0.01）、自主性（r=0.78，p<0.01）和总分（r=0.70，p<0.01）之间存在强烈的正相关，但只有自主性（r=0.89，p<0.01）和总分（r=0.80，p<0.01）之间存在强烈的关系。
在这项纵向队列研究中，视空间能力与腹腔镜技能相关，并随培训而提高。空间可视化可能是腹腔镜专业技能的特征，因为它与腹腔镜住院医师培训计划中的能力发展有明确的关联。
