“…The training and accreditation program FLS only takes into account parameters such as completion time and procedural performance (accuracy error) for evaluation purposes (19,20). However, to better understand surgical gestures and to exploit the possibilities that can offer tracking technologies, a wider range of metrics should be considered and analysed (see Table IV).…”

“…This program consists of web-based study guides and hands-on manual skills practice and training. The manual skills assessment is based on the McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS), which consists of a series of five tasks with an objective scoring system (20). It uses time and accuracy (number of errors) in order to assess each individual task.…”

Minimally invasive surgery is a highly demanding surgical approach regarding technical requirements for the surgeon, who must be trained in order to perform a safe surgical intervention. Traditional surgical education in minimally invasive surgery is commonly based on subjective criteria to quantify and evaluate surgical abilities, which could be potentially unsafe for the patient. Authors, surgeons and associations are increasingly demanding the development of more objective assessment tools that can accredit surgeons as technically competent. This paper describes the state of the art in objective assessment methods of surgical skills. It gives an overview on assessment systems based on structured checklists and rating scales, surgical simulators, and instrument motion analysis. As a future work, an objective and automatic assessment method of surgical skills should be standardized as a means towards proficiency-based curricula for training in laparoscopic surgery and its certification.

“…To shorten learning curves and to reduce accidents and complications, specific LPS and some typical surgical skills, such as suturing or knot tying, must be learnt outside the OR. Although several training devices and methods for laparoscopic skills acquisition have been reported [7][8][9][10][11][12][13][14], most studies focused on models that recreate operative conditions and very few on the specific LPS. Virtual reality models have been proposed in this regard but, as they are still very expensive, a simple and broad implementation (not only at specialised centres) is not feasible today.…”

A valid model for testing and training laparoscopic psychomotor skills

This study aims to evaluate the face and construct validity of the Laparoscopic Skills Testing and Training (LASTT) model, developed by the European Academy of Gynaecological Surgery (EAGS) for assessing laparoscopic psychomotor skills (LPS). This study is designed based on the Canadian Task Force II-1. This study was conducted in workshops organised by the EAGS in 2008 and 2009. One hundred ninety-nine gynaecologists were classified in three groups according to their exposure to laparoscopy (G1: no/little, G2: intermediate, G3: important). Participants performed three repetitions of three exercises (E1: camera navigation, E2: hands-eyes coordination, E3: bimanual coordination) with measurable objectives to accomplish within a limited time frame. The face validity of the model was assessed by an 11-item questionnaire using a 10-cm visual analogue scale. Q1-Q8 evaluated its capacity for testing and training LPS and Q9-Q11 its relevance for actual laparoscopic surgery. The score of each exercise was obtained by dividing the time to correct performed exercise by the number of objectives effectively accomplished. The correlation between E1-E3 scores and the level of exposure to laparoscopy was evaluated, and the scores of the different groups were compared to assess the construct validity. Participants gave a favourable opinion about the model without inter-group differences. In E1-E3, the scores correlated with the level of previous exposure to laparoscopic procedures, moreexperienced participants achieving better results than lessexperienced participants. The data demonstrate the face and construct validity of the LASTT model, suggesting that it can be a useful tool for training and evaluation of LPS in surgical disciplines that perform laparoscopic procedures.

“…48 The MISTELS system was designed to objectively assess basic laparoscopic skills through a series of structured tasks performed under video guidance in a box trainer. 49,50 MISTELS has been shown to discriminate between competent and non-competent laparoscopic surgeons and may be used to evaluate individual skill levels. 51 These box trainers have been studied and validated extensively and have progressed into the Fundamentals of Laparoscopic Surgery training course and evaluation system (FLS).…”

“…55 The MISTELS is used within the FLS to assess technical skill. 50,56 The FLS exams are only available to a few centers in the United States and Canada. Consequently participation In numerous studies, the FLS program has been found to be a valid teaching and assessment tool for laparoscopic knowledge and skills.…”

Background: Conforming to, among other considerations, legal and ethical concerns for patient safety, there is an increasing demand to assess a surgeon's skills prior to performance in the operating room in pursuit of higherquality treatment. Training in minimally invasive surgery (MIS) must therefore be intensified, including team training. New methods to train and assess minimally invasive surgical skills are gaining interest. The goal of this review is to provide instructors with an overview of available MIS training tools. In this review, we discuss currently available simulators for MIS training. Applicability, validity, and construction of simulators are reviewed. Also, some of the leading training programs and assessment methods in MIS are reviewed. Methods: A literature search was performed on studies evaluating surgical task performance on a simulator, reviewing satisfaction with laparoscopic training programs, or validating simulators or assessment methods. Results: Simulators may be divided into simple box trainers and computer-based systems, such as virtual and augmented simulators. All have advantages and disadvantages. An overview is provided of currently available training systems, validity, trainee assessment, and the importance of training programs in MIS. Conclusions:No simulator yet provides the ability to train the entire set of required psychomotor skills or procedures for MIS. A multiyear training program combining various simulators for multiple-level training, including team training, should be constructed.

The MISTELS program to measure technical skill in laparoscopic surgery

Abstract: The MISTELS metrics have excellent reliability, which exceeds the threshold level of 0.8 required for high-stakes evaluations. These findings support the use of MISTELS for evaluation in many different settings, including residency training programs.
