Role of Endo-Trainers (Surgical Simulator) in Laparoscopic Surgical Training


Our study group included 15 third and fourth year surgical residents. There was little variation between the performance of residents of third and fourth year during their initial assessment (time 0), indicating that both sets of residents were not trained to laparoscopic techniques. During the one-month assessment, the residents were randomized to the endotrainer training more effectively on completing their tasks than originally thought.

The inmates trained with the endotrainers carried the peg transfer task (at the beginning of the training it was 5 minutes 52 seconds vs. 2 minutes.

Med. Sci. October 2014, Vol. 22, No. 4 187 in general surgical programs until that time appropriate the additional training for laparoscopic surgery. The introduction of laparoscopic surgical skills for surgical residency is mandatory. The competent functioning of high-level laparoscopic operations is dynamic.

It is important to develop curriculum guidelines for resident training in laparoscopic surgery. There should be measures where resident and faculty training should be applied in high-level laparoscopic surgical skills. As the number of laparoscopic operations increases now, the opportunities for residents to learn essential skills are increased. It will improve the safety of operations. Sanchez-Santos et al worked on a new Laparoscopic bariatric team. The long learning curve may be associated with a higher number of post-operational difficulties. In their study they chose two groups: (1) without formal bariatric laparoscopic training (thirteen surgeons) and (2) formal laparoscopic bariatric training (five surgeons). Post-1 difficulties were more frequent in group 1 of 18.1% (± 7.6) vs. 7.7% (± 1.96, p = 0.046) in group 2; also the mortality was more common in group 1: 0.57% (± 0.87) vs. 0% (p = 0.05) in group 2.

Training in laparoscopic bariatric surgery will play a significant role in significantly reducing post-operative difficulties and mortality. In recent years, simulation has been used to teach technical skills to surgical trainees. In developed countries, there has been a major shift towards the use of simulation-based training.

There are some limitations such as a reduction in working hours for residents in laparoscopic theaters, short training programs, reduced time available in the operating room, and ethical issues of patients. In the future, trainees will learn all the basic skills and skills in a supervised training environment. Simulations are safe for practice and small chances of error. They provide good learning opportunities to standardize trainees’ experience. A wide variety of models are currently available for training. These models include high-trust animal models or cadaveric models that truly reality simulators.


In different studies different models of simulations are used as Giger et al used human cadavers Thiel for laparoscopy training in colon, vascular, hernia and bariatric surgery. In Thiel cadavers, preservation of color and consistency of cadaveric tissue, is maintained. In addition, it would be beneficial to determine which aspects of surgical training are likely to benefit from cadaver training and to preserve the valuable resource for these particular skills.
