“…With regard to the metrics used for our tasks, excellent inter-rater reliability highlighted very high consistency of the scores from different raters using simple, objective metrics similar to the FLS scoring system [1,11]. This allows for assessment of performance by direct observation and does not require recorded performances or any sophisticated assessment systems such as motion analysis [12].…”

“…The transfer of quality control and quality assessment from simulation-based training into the operation room, however, is not established yet. In addition, it is shown that laparoscopic operative skills are not a precise predictor for the quality of camera navigation; hence, an independent assessment of camera navigation skills is essential for objective quality control [7,14]. With this study, we present the first intraoperative, structured assessment of camera navigation quality in advanced laparoscopic colorectal surgery.…”

“…The importance of high-quality camera assistance has come more into focus over the last years. Several studies were conducted to assess and improve laparoscopic camera navigation, though all these studies were conducted with virtual reality simulators or box trainers [4,[6][7][8][9]. With the structured assessment of laparoscopic camera navigation skills (SALAS) score, we developed the first objective intraoperative assessment tool for laparoscopic camera assistance [10].…”

Purpose In advanced minimally invasive surgery the laparoscopic camera navigation (LCN) quality can influence the flow of the operation. This study aimed to investigate the applicability of a scoring system for LCN (SALAS score) in colorectal surgery and whether an adequate scoring can be achieved using a specified sequence of the operation. Methods The score was assessed by four blinded raters using synchronized video and voice recordings of 20 randomly selected laparoscopic colorectal surgeries (group A: assessment of the entire operation; group B: assessment of the 2nd and 3rd quartile). Experience in LCN was defined as at least 100 assistances in complex laparoscopic procedures. Results The surgical teams consisted of three residents, three fellows, and two attendings forming 15 different teams. The ratio between experienced and inexperienced camera assistants was balanced (n = 11 vs. n = 9). Regarding the total SALAS score, the four raters discriminated between experienced and inexperienced camera assistants, regardless of their group assignment (group A, p < 0.05; group B, p < 0.05). The score's interrater variability and reliability were proven with an intraclass correlation coefficient of 0.88. No statistically relevant correlation was achieved between operation time and SALAS score. Conclusion This study presents the first intraoperative, objective, and structured assessment of LCN in colorectal surgery. We could demonstrate that the SALAS score is a reliable tool for the assessment of LCN even when only the middle part (50%) of the procedure is analyzed. Construct validity was proven by discriminating between experienced and inexperienced camera assistants.

“…This is an aspect of future research and should be considered by surgical teachers, trainees, and the industry for realistic simulator software development. Current curricula for laparoscopic education such as the Fundamentals of laparoscopic surgery (FLS) and its derivatives do not contain complication management (18).…”

Objective: The aim of this study was to compare the impact of induced bleeding complication training with regular training on a virtual reality laparoscopic (VRL) simulator.Summary of Background Data: Although bleeding complications occur rarely during laparoscopic surgery, they usually arise without warning and may have severe consequences for the patient because complication management training is not currently widespread.Methods: Third-year medical students (n=41) were randomly selected for two curricular courses on how to perform a bimanual task on a VRL simulator. Both the regular training group (RTG) and the induced bleeding complication training (ICT) group performed two regular training sessions and 9 training sessions. For The ICT group the training sessions were with a bleeding complication.Results: The two groups were comparable regarding their initial performance levels and improved significantly in task time and handling economics throughout the course (P <0.001). When a bleeding complication occurred during the initial phase, performance parameters were significantly worse (P <0.05). During a bleeding complication, the ICT group showed a significant improvement in time, handling economics, and blood loss (P <0.001) throughout the training course, whereas the RTG group showed no improvement.Conclusion: Induced complication training has a positive influence on the management of bleeding on the VRL simulator. Structured laparoscopic complication management training should be implemented during surgical education as an add-on to regular procedural training.

Camera navigation and cannulation: validity evidence for new educational tasks to complement the Fundamentals of Laparoscopic Surgery Program

Abstract: This study provides preliminary validity evidence for the metrics of these new tasks. The value of adding these tasks to the FLS manual skills assessment is marginal in terms of predicting level of training.
