HYPOTHESIS: The investigators aim is to design a standardized evidence-based comprehensive laparoscopic curriculum that focuses on cognitive knowledge, surgical skills, and team training exercises. The investigators hypothesize that residents in the experimental curriculum-trained group will perform better than the residents in the traditional residency curriculum-trained group on a cognitive examination, a technical skills examination, and in the operating room. The operating room performance will be judged by blinded experts on a previously validated evaluation tool.
