“…Another quality metricdetection of idle states-has not gained much attention. Nevertheless, studies show significant differences between a novice surgeon and a more experienced surgeon on suture tasks and more complex procedural chores [49,50]. The principie behind this metric is that a novice surgeon takes more time to plan the next move than a more experienced surgeon.…”

“…Typically, this assessment requires the presence of a trained supervisor, and the definition of clear, structured checklists are necessary [28,53]. Table 6 shows the most widespread HMT capture systems for surgical assessment identified in the literature [44][45][46][47][48][49][50][51][52][53][54][55][88][89][90][91]. Their classification can be done according to the nature of the acquired information.…”

“…Also, not all HMT devices are suited for portability: the bulkiness and configuration of some of them make them fit only for a closed-up number of box-trainer tasks, and compromises their possible migration to the OR [20]. Exceptions to this are BlueDRA-GON, which has been reported to be used on live animáis [49], and ICSAD, validated while performing surgeries on real patients with the help of video assistance [96,97].…”

“…Sequential analysis of surgical tasks by Markov modeling has been the most common approach [49,50,[106][107][108][109][110][111]. Simple Markov models (MM) interpret sequences of actions as a series of steps, defined by a closed number of states and the probabilities from going from one state to another.…”

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).
