BACKGROUND The duodenojejunal bypass liner (DJBL) (EndoBarrier Gastrointestinal Liner) is an endoscopically placed and removable intestinal liner that creates a duodenojejunal bypass resulting in weight loss and improvement in type 2 diabetes mellitus. OBJECTIVE Weight loss before bariatric surgery to decrease perioperative complications. DESIGN(More)
As clinical outcome data are increasingly tied to hospital reimbursement, balancing quality care with training of surgical residents has become critical. We used the ACS-NSQIP database to determine impact of resident participation in laparoscopic gastric bypass on 30-day morbidity and mortality. We queried the ACS-NSQIP database from 1/2005 to 12/2012 for(More)
Renal cell carcinoma (RCC) is a rare adult malignancy, and one-third of cases present with distant metastases at the time of diagnosis. Early gastric metastasis is exceedingly rare. We describe an adult male with synchronous gastric metastasis of RCC at the time of diagnosis in the absence of gastrointestinal symptoms. We report the fifth case of RCC with(More)
BACKGROUND Our aim was to report the longitudinal assessment of technical performance of general surgery residents on select tasks from multiple programs over a 2-year period. METHODS An institutional review board-approved, multi-institutional collaborative study was undertaken with yearly resident performance assessments over a 3-year period. General(More)
BACKGROUND Opportunities exist to revise the current residency selection process to capture desirable candidate competencies. We examined the extent to which components of the American College of Surgeons/Association for Surgical Education simulation-based medical student curriculum combined with a teamwork activity could be used as potential screening(More)
Since fundamentals of laparoscopic surgery (FLS) represents a minimum proficiency standard for laparoscopic surgery, more advanced proficiency standards are required to address the needs of current surgical training. We wanted to evaluate the acceptance and discriminative ability of a novel set of skills building on the FLS model that could represent a more(More)
Surgery residents are required to achieve performance milestones to advance in their residency. Level-specific, technical performance norms that could be used as milestones, however, do not currently exist. Our aim was to develop level-specific, technical performance norms for general surgery residents on select simulated tasks across multiple institutions.(More)
