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)
BACKGROUND Natural orifice transluminal endoscopic surgery (NOTES) ventral hernia repair could avoid abdominal wall incisions. The infectious risk for mesh placement is of concern. We compared NOTES with laparoscopic mesh placement. METHODS Thirty-seven swine were randomized to abdominal wall polypropylene mesh placement via NOTES or laparoscopy or NOTES(More)
INTRODUCTION Surgical residents have learned flexible endoscopy by practicing on patients in hospital settings under the strict guidance of experienced surgeons. Simulation is often used to "pretrain" novices on endoscopic skills before real clinical practice; nonetheless, the optimal method of training remains unknown. The purpose of this study was to(More)
BACKGROUND The use of simulation for minimally invasive surgery (MIS) skills training has many advantages over current traditional methods. One advantage of simulation is that it enables an objective assessment of technical performance. The purpose of this study was to determine whether the ProMIS augmented reality simulator could objectively distinguish(More)
Reoperative bariatric surgery is required in 10 per cent to 20 per cent of patients secondary to weight regain or complications of the previous procedure. This study evaluates the feasibility of performing the revision procedure laparoscopically. A retrospective review of all patients undergoing revision of a previous weight loss procedure between October(More)
BACKGROUND Certification in fundamentals of laparoscopic surgery (FLS) is required by the American board of surgery for graduating residents. This study aimed to evaluate the feasibility and need for certifying practicing surgeons and to assess proficiency of operating room (OR) personnel. METHODS Through a patient safety and health care delivery(More)
Enabling trainees to acquire advanced technical skills before they begin the operating room experience benefits both trainee and patient. Whether medical students who had received exclusively simulation-based training could perform laparoscopic suturing and knot-tying as well as senior surgery residents was determined. Simulators were used to train 11(More)
BACKGROUND The Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) has been well validated as a training device for laparoscopic skills. It has been demonstrated that training to a level of proficiency on the simulator significantly improves operating room performance of laparoscopic cholecystectomy. The purpose of this project was to obtain a(More)
BACKGROUND The ideal objective assessment method for laparoscopic technical skills is difficult to achieve in the operating room. Recent "VR2OR" studies have used a blinded, 2-reviewer error-based video tape analysis for intraoperative performance assessment. This study examines the validity of this methodology applied to laparoscopic intracorporeal(More)
BACKGROUND We compared traditional pedagogical approaches such as time- and repetition-based methods with proficiency-based training. METHODS Laparoscopic novices were assigned randomly to 1 of 3 training conditions. In experiment 1, participants in the time condition practiced for 60 minutes, participants in the repetition condition performed 5 practice(More)
