BACKGROUND Simulated environments present challenges to both clinical experts and novices in laparoscopic surgery. Experts and novices may have different expectations when confronted with a novel simulated environment. The LapSim is a computer-based virtual reality laparoscopic trainer. Our aim was to analyze the performance of experienced basic(More)
BACKGROUND There currently exist several training modules to improve performance during video-assisted surgery. The unique characteristics of robotic surgery make these platforms an inadequate environment for the development and assessment of robotic surgical performance. METHODS Expert surgeons (n=4) (>50 clinical robotic procedures and >2 years of(More)
Postoperative leaks after laparoscopic Roux-en-Y gastric bypass (LRYGB) are a source of morbidity and mortality. Any intervention that would decrease leak rates after LRYGB would be useful. This investigation tested the hypothesis that postoperative leak rates are lower after LRYGB with the routine use of intraoperative endoscopy (EN). Consecutive patients(More)
The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine(More)
We sought to study our mid-term outcomes and our patient's perceptions of robotically-assisted coronary artery bypass (RACAB). The daVinci robotic system was utilized to harvest and prepare the internal thoracic artery (ITA) as well as to open the pericardium and identify the target vessels. Anastomoses were performed by hand on the beating heart through(More)
BACKGROUND : Robotically assisted left ventricular (LV) lead placement is an effective minimally invasive rescue procedure for cardiac resynchronization in the setting of failed coronary sinus lead insertion. The long-term response rate and durability of this technique has not been reported. The authors evaluated the midterm outcome of biventricular pacing(More)
BACKGROUND : Robotic technology has facilitated the evaluation and treatment of anterior mediastinal pathology. We describe a 3-year experience using the da Vinci Robotic Surgical System to perform thymectomies for a range of diseases. METHODS : From March 2002 to November 2004, 9 patients (3 myasthenia gravis, 3 mediastinal mass, 2 myasthenia gravis plus(More)
There are two approaches to gene discovery for diseases when genetic susceptibility has been implicated by clinical genetic or case-control studies: (1) genome-wide screening and (2) evaluation of candidate genes. Each has specific advantages and disadvantages. The principal advantage of genome-wide screening is that it is impeccably objective in as much as(More)
