Abstract
Background: Although camera navigation is integral to pediatric endoscopic surgery, no validated framework exists for assessing laparoscopist performance. This study evaluated the validity of a modified Objective Structured Assessment of Camera Navigation Skills (OSA-CNS) and investigated how laparoscopist performance influenced procedural safety.
Methods: This retrospective study evaluated unilateral single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) procedures performed in males at our institution between January and December 2022. 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-Wallis test. The associations of laparoscopist performance with errors, events, and procedure time were analyzed using surgeon-clustered linear regression.
Results: Briefly, 25 unilateral procedures with 185 errors and 40 events were included. The median procedure time was 23.3 (20.3-29.4) min. The modified OSA-CNS demonstrated excellent inter-rater reliability (intraclass correlation coefficient = 0.96) and internal consistency (Cronbach's α = 0.88-0.91). It distinguished performance across laparoscopists with differing experiences (P = .0020). Higher laparoscopist scores were associated with fewer errors (β = -0.19, 95% CI: -0.34 to -0.04; P = .025) but not with event counts or procedure time.
Conclusions: The modified OSA-CNS is reliable and valid for evaluating laparoscopist performance in pediatric SILPEC. Its ability to reflect skill differences and its association with error frequency underscore its value in surgical education and intraoperative safety improvement.
期刊介绍：
Journal of Laparoendoscopic & Advanced Surgical Techniques (JLAST) is the leading international peer-reviewed journal for practicing surgeons who want to keep up with the latest thinking and advanced surgical technologies in laparoscopy, endoscopy, NOTES, and robotics. The Journal is ideally suited to surgeons who are early adopters of new technology and techniques. Recognizing that many new technologies and techniques have significant overlap with several surgical specialties, JLAST is the first journal to focus on these topics both in general and pediatric surgery, and includes other surgical subspecialties such as: urology, gynecologic surgery, thoracic surgery, and more.
