Comparison of single access devices during cut and suturing tasks on simulator.

Background: Published comparisons of the different available laparoendoscopic single-site surgery (LESS) devices focused on its economic cost and technical aspects. With this study, we aimed to objectively compare the use of three different LESS access devices in controlled experimental tasks.

Materials And Methods: Twenty subjects participated in simulator trials.

Performance analysis on physical simulator of four different instrument setups in laparo-endoscopic single-site (LESS) surgery.

Background: Over the past decades, minimally invasive surgery has undergone continuous development due to the demand for scarless results, with laparo-endoscopic single-site (LESS) surgery constituting one of today's most favored alternatives. In this study, we aim to assess the relative technical difficulty and performance benefits of dynamic articulating and pre-bent instruments, either combined with conventional laparoscopic tools or not, during the completion of two basic tasks hands-on simulator.

Methods: A total of 20 surgeons were included and performed two basic simulator tasks-coordination and cutting-carried out using four different combinations of LESS-designed and straight conventional laparoscopy instruments.

[Training and research in urologic laparoscopic surgery. Design of training programs and experimental models of renal tumor].

We present our experience with surgical training programs development for basic and advanced laparoscopic urological surgery. Both training programs consist of 21 and 28 hours respectively. Basic surgical programs start with general knowledge of ergonomics and instrumentation, there after, attendants acquire basic skills on physical simulator.

[Ergonomics in laparoscopic surgery and its importance in surgical training].

Despite the many advantages that laparoscopic surgery has for patients, it involves a series of risks for the surgeon. These are related to the reduced freedom of movement and forced postures which lead to greater muscle fatigue than with conventional surgery. In laparoscopic surgery there are few references on the introduction of training programs in ergonomics, despite the numerous advantages demonstrated in other disciplines.

[Training design and improvement of technical skills in the transvaginal cholecystectomy (NOTES)].

Introduction: The current surgical scenario of the surgery through natural orifices or <> requires acquiring new technical skills by the surgeon. We introduce the initial experience of the Minimally Invasive Surgery Centre Jesús Usón (MISCJU) in the design and setting-up of a surgical training programme using the the natural orifices approach for the acquisition of surgical skills and abilities, based on the preliminary trials in simulators and a pig model.

Material And Methods: After initial training, using a laparoscopic pelvic-trainer, 7 female pigs, with weights between 35-40 kg, were operated on.
