Currently, no optimal curriculum exists for the Fundamentals of Laparoscopic Surgery (FLS) manual skills training program. The objective was to create a proficiency-based training curriculum that would allow both successful completion of the FLS manual skills exam and improved performance in the operating room. Two experienced laparoscopic surgeons(More)
SUMMARY BACKGROUND DATA To inform surgeons about the practical issues to be considered for successful integration of virtual reality simulation into a surgical training program. The learning and practice of minimally invasive surgery (MIS) makes unique demands on surgical training programs. A decade ago Satava proposed virtual reality (VR) surgical(More)
Surgery has always been a dynamic discipline. It has a long history of groundbreaking innovations that dramatically improved the way patients were treated and surgery was practiced. However, nothing could have prepared the surgical community for the revolutionary advances of the last 2 decades. Almost overnight, the traditional open approach to surgery was(More)
The objective of this study was to determine whether the GI Mentor II virtual reality simulator can distinguish the psychomotor skills of intermediately experienced endoscopists from those of novices, and do so with a high level of consistency and reliability. A total of five intermediate and nine novice endoscopists were evaluated using the EndoBubble(More)
The fundamentals of laparoscopic surgery (FLS) program has been extensively validated for use as a high-stakes examination for certification purposes, but optimal methods for its use in skills training have not been described. This study aimed to investigate the feasibility of implementing a proficiency-based FLS skills training curriculum and to evaluate(More)
Contraction is a well-documented phenomenon occurring within two months of mesh implantation. Its etiology is unknown, but it is suggested to occur as a result of inadequate tissue ingrowth into the mesh and has been associated with hernia recurrence. In continuation of our previous studies, we compared tissue ingrowth characteristics of large patches of(More)
BACKGROUND Loss of depth cues is a major challenge facing surgeons performing video-assisted surgery (VAS). Whether the degradation of image quality from a video-displayed image plays a direct role in performance of VAS has not been studied. METHODS Twenty-four volunteer novice subjects were randomized to binocular direct-vision (BDV), monocular(More)
Given the dynamic nature of modern surgical education, determining factors that may improve the efficiency of laparoscopic training is warranted. The objective of this study was to analyze whether perceptual, visuo-spatial, or psychomotor aptitude are related to the amount of training required to reach specific performance-based goals on a virtual reality(More)
Current skills assessment in the Fundamentals of Laparoscopic Surgery (FLS) program is labor intensive, requiring one proctor for every 1–2 subjects. The ProMIS Augmented Reality (AR) simulator (Haptica, Dublin IR) allows for objective assessment of physical tasks through instrument tracking technology. We hypothesized that the ProMIS metrics could(More)
BACKGROUND Advanced surgical skills such as laparoscopic suturing are difficult to learn in an operating room environment. The use of simulation within a defined skills-training curriculum is attractive for instructor, trainee, and patient. This study examined the impact of a curriculum-based approach to laparoscopic suturing and knot tying. STUDY DESIGN(More)
