BACKGROUND Current literature suggests that novices reach a plateau after two to seven trials when training on the MIST VR laparoscopic virtual reality system. We hypothesize that significant benefit may be gained through additional training. MATERIALS AND METHODS Second-year medical students (n = 12) voluntarily enrolled under an IRB-approved protocol(More)
HYPOTHESIS Expert levels can be developed for use as training end points for a basic video-trainer skills curriculum, and the levels developed will be suitable for training. DESIGN Fifty subjects with minimal prior simulator exposure were enrolled using an institutional review board-approved protocol. As a measure of baseline performance, medical students(More)
Laparoscopic training using virtual reality has proven effective, but rates of skill acquisition vary widely. We hypothesize that training to predetermined expert levels may more efficiently establish proficiency. Our purpose was to determine expert levels for performance-based training. Four surgeons established as laparoscopic experts performed 11(More)
This paper describes a rare right paraduodenal hernia discovered during an elective laparoscopic colon resection. Our patient was a 60-year-old Asian man with a history of multiple bouts of diverticulitis and a lifelong history of mild constipation and postprandial abdominal pain. Prior CT scans and preoperative barium enema confirmed the diagnosis of(More)
BACKGROUND The "Southwestern" videotrainer stations have demonstrated concurrent validity (transferability to the operating room). The purpose of this study was to evaluate the Southwestern stations for construct validity (the ability to discriminate between subjects at different levels of experience). MATERIALS AND METHODS From two surgical training(More)
BACKGROUND AND OBJECTIVE Nonparasitic cysts are rare clinical lesions of the spleen. Causes include congenital malformations and trauma. Historically, management has entailed partial or total splenectomy using an open approach. Recently, laparoscopic approaches have been developed. In this report, we describe laparoscopic marsupialization of a giant splenic(More)
