Impact of the Endoscopic Sinus Surgical Simulator on Operating Room Performance

THE LARYNGOSCOPE, Issue 7 2002
Charles V. Edmond Jr. MD
Abstract Objectives/Hypothesis The aim of this study is to evaluate an endoscopic sinus surgical simulator (ESS) as a training device and to introduce a methodology to assess its impact on actual operating room performance. Study Design Prospective evaluation of the endoscopic sinus surgical simulator as a trainer. Methods Ten junior and senior ear, nose and throat residents served as subjects, some of whom had prior training with the simulator. The evaluation team collected several measures, which were analyzed for a statistical correlation, including simulator scores, operating room performance rating, ratings of videotaped operating room procedures, and surgical competency rating. Results These findings suggest the ESS simulator positively affects initial operating room performance across all measures as judged by senior surgeons rating anonymous videotapes of those procedures. The two simulation-trained residents were rated consistently better than the other two residents across all measures. These differences approached statistical significance for two items: anterior ethmoidectomy (P = .06;P <.05) and surgical confidence (P = .09;P <.05). In addition, the 3 subjects with the highest overall scores on the competency evaluation also had 3 of the 4 highest cumulative simulation times. Conclusions The endoscopic sinus surgical simulator is a valid training device and appears to positively impact operating room performance among junior otolaryngology residents. [source]

This model has regularly been used in cutaneous surgical courses that we have organized. Either adding more cyanoacrylic glue or allowing more time for the paint ball to absorb fluid from surrounding tissue can also adjust the degree of difficulty. conclusions. The degree of correlation with lifelike cutaneous pathology is such that we recommend that all courses involved in basic skin surgery should consider using the porcine sebaceous cyst model when teaching excision of sebaceous cysts.

Assessing suturing techniques using a virtual reality surgical simulator

MICROSURGERY, Issue 6 2010

Advantages of virtual-reality simulators surgical skill assessment and training include more training time, no risk to patient, repeatable difficulty level, reliable feedback, without the resource demands, and ethical issues of animal-based training. We tested this for a key subtask and showed a strong link between skill in the simulator and in reality. Suturing performance was assessed for four groups of participants, including experienced surgeons and naive subjects, on a custom-made virtual-reality simulator. Each subject tried the experiment 30 times using five different types of needles to perform a standardized suture placement task. Traditional metrics of performance as well as new metrics enabled by our system were proposed, and the data indicate difference between trained and untrained performance. In all traditional parameters such as time, number of attempts, and motion quantity, the medical surgeons outperformed the other three groups, though differences were not significant. However, motion smoothness, penetration and exit angles, tear size areas, and orientation change were statistically significant in the trained group when compared with untrained group. This suggests that these parameters can be used in virtual microsurgery training. © 2010 Wiley-Liss, Inc. Microsurgery 30:479,486, 2010. [source]

Graphic and haptic modelling of the oesophagus for VR-based medical simulation

THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 3 2009

Abstract Background Medical simulators with vision and haptic feedback have been applied to many medical procedures in recent years, due to their safe and repetitive nature for training. Among the many technical components of the simulators, realistic and interactive organ modelling stands out as a key issue for judging the fidelity of the simulation. This paper describes the modelling of an oesophagus for a real-time laparoscopic surgical simulator. Methods For realistic simulation, organ deformation and tissue cutting in the oesophagus are implemented with geometric organ models segmented from the Visible Human Dataset. The tissue mechanical parameters were obtained from in vivo animal experiments and integrated with graphic and haptic devices into the laparoscopic surgical simulation system inside an abdominal mannequin. Results This platform can be used to demonstrate deformation and incision of the oesophagus by surgical instruments, where the user can haptically interact with the virtual soft tissues and simultaneously see the corresponding organ deformation on the visual display. Conclusions Current laparoscopic surgical training has been transformed from the traditional apprenticeship model to simulation-based methods. The outcome of the model could replace conventional training systems and could be useful in effectively transferring surgical skills to novice surgeons. Copyright © 2009 John Wiley & Sons, Ltd.

Minimally invasive surgical technologies: Challenges in education and training

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2010

Abstract The laparoscopic revolution has fundamentally changed surgical technology. However, this new technology, with its unique psychomotor adaptations, has been a challenge for both experienced and novice surgeons. This review summarizes the history of practical education and training methods and those currently used to ensure surgeons safely practice these new surgical skills. Traditional training boxes, augmented reality simulators and virtual reality simulators represent recently developed educational tools. There are objective programs that subsequently assess the results of training by these simulation methods. Additionally, the advent of robotics in laparoscopic surgery has been accompanied by the introduction of computer-based robotic surgical simulators. Surgical curricula should also include non-technical skills training, particularly as global certification of technical and non-technical surgical skills is expected in the near future. Ultimately, these new systems of surgical simulation contribute to a decrease in surgical error as well as with reduced morbidity and mortality. [source]

Training in minimally invasive surgery: An Asian perspective

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2009

Abstract Minimally invasive surgery, which requires a different approach than used in the past, has created a revolution not only in surgical practice but also in surgical education. To overcome the challenges and difficulties of minimally invasive surgery, training needs to be done outside the operating room and away from the patient. New educational tools have emerged in the form of surgical simulators, including trainer boxes, virtual reality simulators and hybrid simulators. Many studies have confirmed the effectiveness of both box trainers and virtual reality simulators for surgical education. The integration of simulators into a structured laparoscopic skills curriculum creates an ideal training ground for acquiring the necessary skills for minimally invasive surgery. It has also been proven that this training model is effective for transferring acquired skills into the clinical setting. [source]
