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.

In recent years, many efforts have been made to reduce the trauma of surgical access further by the use of single-incision laparoscopic surgery (SILS). The Ergo-Lap (ergonomic laparoscopic) simulator was taken to the 20th International Congress of the European Association for Endoscopic Surgery (EAES) in 2012 in Brussels, Belgium. During the congress, the simulator was assessed by 13 general surgeons with different SILS experience using a standardized questionnaire to determine the usability of the Ergo-Lap simulator training for basic SILS skills. Eleven of the 13 participants rated the simulator as an attractive simulator (attractive here means arousing interest of the trainees). For the aspects of training in an ergonomic way, 12 of 13 participants rated it as good to excellent because the work space and task panel location can be adjusted according to the length of instruments. Also, 92% (12 of 13) thought the Ergo-Lap simulator was useful for practicing basic SPLS skills. And 85% (11 of 13) thought it was very easy to use. For SILS skills training, this in~xpensive and portable Ergo-Lap simulator offers a feasible training opportunity to help trainees practice their SILS skills under ergonomic conditions.@en

Objective: The cost of laparoscopic simulators restricts the wide use of simulation for training of basic psychomotor skills. This paper describes the scientifically-based development of an inexpensive and portable Ergonomic Laparoscopic Skills (Ergo-Lap) simulator with multiple tasks. Material and methods: The design of this Ergo-Lap simulator and related training task panel was based on scientific research regarding the representative skills and the ergonomic guidelines for laparoscopic surgery. A user-centred design approach was followed. Fifty-three surgical participants with variable laparoscopic experience (14 medical students, 27 surgeons in training, and 12 experienced laparoscopic surgeons) performed several tasks on the prototype and gave their feedback by filling out a 5-point scale Likert scale questionnaire. Results: The results of the usability evaluation showed that the participants regarded the Ergo-Lap simulator as a useful device to practice the basic and advanced skills effectively. Forty-three of the 53 participants indicated they would like to purchase this simulator since it is easy to use and challenges their laparoscopic skills. Conclusions: For laparoscopic skills training, this inexpensive Ergo-Lap simulator with diverse task choices offers a simple training opportunity for trainees who want to practice laparoscopic skills at home or at the office.
