“…Moreover, they are capable of performing unsupervised assessment of trainees in a whole range of efficiency and quality parameters. Nevertheless, these studies are in many cases scarce, and others report negative [124][125][126] or inconclusive results [77]. This is often the case considering the high variability between studies, concerning participants, definition of surgical levéis, and in general the experiments' contour conditions (previous training in the system, number of repetitions allowed, etc.).…”

Training and assessment paradigms for laparoscopic surgical skills are evolving from traditional mentortrainee tutorship towards structured, more objective and safer programs. Accreditation of surgeons requires reaching a consensus on metrics and tasks used to assess surgeons' psychomotor skills. Ongoing development of tracking systems and software Solutions has allowed for the expansión of novel training and assessment means in laparoscopy. The current challenge is to adapt and include these systems within training programs, and to exploit their possibilities for evaluation purposes. This paper describes the state of the art in research on measuring and assessing psychomotor laparoscopic skills. It gives an overview on tracking systems as well as on metrics and advanced statistical and machine learning techniques employed for evaluation purposes. The later ones have a potential to be used as an aid in deciding on the surgical competence level, which is an important aspect when accreditation of the surgeons in particular, and patient safety in general, are considered. The prospective of these methods and tools make them complementary means for surgical assessment of motor skills, especially in the early stages of training. Successful examples such as the Fundamentáis of Laparoscopic Surgery should help drive a paradigm change to structured curricula based on objective parameters. These may improve the accreditation of new surgeons, as 1 To whom correspondence and reprint requests should be addressed at Bioengineering and Telemedicine Centre (GBT), ETSI Telecomunicación, Universidad Politécnica de Madrid (UPM).

“…A number of small studies ( Table 2) have attempted to demonstrate construct validity of the LapSim [26][27][28][29][30][31][32][33][34][35]. This is the ability of the software to measure what it claims to measure and is established most often by differentiating between the performance scores of groups or individuals with different levels of surgical competence.…”

The LapSim virtual reality simulator: promising but not yet proven

Although the LapSim currently does not have any proven significant advantages over video trainers in terms of basic skills instruction and although the results of validation studies are variable, the potential for such technology to have a huge impact on surgical training is apparent. Work to determine standardized learning curves and proficiency criteria for different levels of trainees is incomplete. Moreover, defining which performance parameters measured by the LapSim accurately determine laparoscopic skill is complex. Further technological advances will undoubtedly improve the efficacy of the LapSim, and the results of large multicenter trials are anticipated.

“…The construct and predictive validity of these tasks has previously been established. 17,18,[24][25][26][27][28] The difficulty level for each task was customized to be intermediate between the built-in medium and hard settings. The AccuTouch endoscopy simulator contains multiple case scenarios for flexible sigmoidoscopy, diagnostic colonoscopy, and colonoscopy with polypectomy.…”
