Objective Laparoscopic skills can be improved effectively through laparoscopic simulation. The purpose of this study was to verify the face and content validity of a new portable Ergonomic Laparoscopic Skills simulator (Ergo-Lap simulator) and assess the construct validity of the Ergo-Lap simulator in 4 basic skills tasks. Design Four tasks were evaluated: 2 different translocation exercises (a basic bimanual exercise and a challenging single-handed exercise), an exercise involving tissue manipulation under tension, and a needle-handling exercise. Task performance was analyzed according to speed and accuracy. The participants rated the usability and didactic value of each task and the Ergo-Lap simulator along a 5-point Likert scale. Setting Institutional academic medical center with its affiliated general surgery residency. Participants Forty-six participants were allotted into 2 groups: a Novice group (n = 26, <10 clinical laparoscopic procedures) and an Experienced group (n = 20, >50 clinical laparoscopic procedures). Results The Experienced group completed all tasks in less time than the Novice group did (p < 0.001, Mann-Whitney U test). The Experienced group also completed tasks 1, 2, and 4 with fewer errors than the Novice group did (p < 0.05). Of the Novice participants, 96% considered that the present Ergo-Lap simulator could encourage more frequent practice of laparoscopic skills. In addition, 92% would like to purchase this simulator. All of the experienced participants confirmed that the Ergo-Lap simulator was easy to use and useful for practicing basic laparoscopic skills in an ergonomic manner. Most (95%) of these respondents would recommend this simulator to other surgical trainees. Conclusions This Ergo-Lap simulator with multiple tasks was rated as a useful training tool that can distinguish between various levels of laparoscopic expertise. The Ergo-Lap simulator is also an inexpensive alternative, which surgical trainees could use to update their skills in the skills laboratory, at home, or in the office.@en

Objective: To establish whether a systematized approach to self-assessment in a laparoscopic surgical skills course improves accordance between expert- and self-assessment. Design: A systematic training course in self-assessment using Competency Assessment Tool was introduced into the normal course of evaluation within a Laparoscopic Surgical Skills training course for the test group (n = 30). Differences between these and a control group (n = 30) who did not receive the additional training were assessed.Setting: Catharina Hospital, Eindhoven, The Netherlands (n = 27), and GSL Medical College, Rajahmundry, India (n = 33). Participants: Sixty postgraduate year 2 and 3 surgical residents who attended the 2-day Laparoscopic Surgical Skills grade 1 level 1 curriculum were invited to participate.Results: The test group (n = 30) showed better accordance between expert- and self-assessment (difference of 1.5, standard deviation [SD] = 0.2 versus 3.83, SD = 0.6, p = 0.009) as well as half the number (7 versus 14) of cases of overreporting. Furthermore, the test group also showed higher overall mean performance (mean = 38.1, SD = 0.7 versus mean = 31.8, SD = 1.0, p < 0.001) than the control group (n = 30). The systematic approach to self-assessment can be viewed as responsible for this and can be seen as "reflection-before-practice" within the framework of reflective practice as defined by Donald Schon. Conclusion: Our results suggest that "reflection-before-practice" in implementing self-assessment is an important step in the development of surgical skills, yielding both better understanding of one's strengths and weaknesses and also improving overall performance.@en
