Virtual Operating Room Simulation Setup (VORSS) for Procedural Training in Minimally Invasive Surgery: a Pilot Study

Virtual reality (VR) training is widely used in several minimal invasive surgery (MIS) training curricula for procedural training. However, VR training in its current state lack immersive training environments, such as using head-mounted displays that is implemented in military or aviation training and even entertainment. The virtual...

Validation of Motion Tracking Software for Evaluation of Surgical Performance in Laparoscopic Cholecystectomy

Motion tracking software for assessing laparoscopic surgical proficiency has been proven to be effective in differentiating between expert and novice performances. However, with several indices that can be generated from the software, there is no set threshold that can be used to benchmark performances. The aim of this study was to identify...

Competency assessment tool for laparoscopic suturing: Development and reliability evaluation

Background: Laparoscopic suturing can be technically challenging and requires extensive training to achieve competency. To date no specific and objective assessment method for laparoscopic suturing and knot tying is available that can guide training and monitor performance in these complex surgical skills. In this study we aimed to develop a...

Construct, content and face validity of the eoSim laparoscopic simulator on advanced suturing tasks

Background: The purpose of this study was to validate the eoSim, an affordable and mobile inanimate laparoscopic simulator with instrument tracking capabilities, regarding face, content and construct validity on complex suturing tasks. Methods: Participants recruited for this study were novices (no laparoscopic experience), target group for...

A software-based tool for video motion tracking in the surgical skills assessment landscape

Background: The use of motion tracking has been proved to provide an objective assessment in surgical skills training. Current systems, however, require the use of additional equipment or specialised laparoscopic instruments and cameras to extract the data. The aim of this study was to determine the possibility of using a software-based...

Single versus multimodality training basic laparoscopic skills

Introduction - Even though literature provides compelling evidence of the value of simulators for training of basic laparoscopic skills, the best way to incorporate them into a surgical curriculum is unclear. This study compares the training outcome of single modality training with multimodality training of basic laparoscopic skills. Methods -...

Training for laparoscopic Nissen fundoplication with a newly designed model: A replacement for animal tissue models?

Camera navigation and tissue manipulation: Are these laparoscopic skills related?

Background: It is a tacit assumption that clinically based expertise in laparoscopic tissue manipulation entails skilfulness in angled laparoscope navigation. The main objective of this study was to investigate the relation between these skills. To this end, face and construct validity had to be established for the place arrow (PA) and camera...

Augmented reality simulation for laparoscopic training realistic haptic feedback and meaningful assessment

Meaningful assessment method for laparoscopic suturing training in augmented reality

To be an effective training tool, a laparoscopic simulator has to provide metrics that are meaningful and informative to the trainee. Time, path length and smoothness are often used parameters, but are not very informative on the quality of the performance. This study aims to validate a newly developed assessment method for laparoscopic suturing...

Suturing training in Augmented Reality: Gaining proficiency in suturing skills faster

Background: Providing informative feedback and setting goals tends to motivate trainees to practice more extensively. Augmented Reality simulators retain the benefit of realistic haptic feedback and additionally generate objective assessment and informative feedback during the training. This study researched the performance curve of the adapted...

Expert and construct validity of the Simbionix GI Mentor II endoscopy simulator for colonoscopy

Objectives The main objectives of this study were to establish expert validity (a convincing realistic representation of colonoscopy according to experts) and construct validity (the ability to discriminate between different levels of expertise) of the Simbionix GI Mentor II virtual reality (VR) simulator for colonoscopy tasks, and to assess the...

Acquiring basic endoscopy skills by training on the GI Mentor II

Augmented versus virtual reality laparoscopic simulation: What is the difference? A comparison of the ProMIS augmented reality laparoscopic simulator versus LapSim virtual reality laparoscopic simulator
