The residents will then perform a laparoscopic tubal ligation with a faculty member when they begin their Benign Gynecology rotation. Each resident will subsequently be randomized either traditional teaching (no simulator) or five 30-minute faculty-directed sessions at the Laparoscopic Simulator Lab. Those randomized to simulation training can practice and perform as many repetitions necessary on the simulator to achieve proficiency. Prior to completing the rotation, the residents will perform another laparoscopic tubal ligation with a faculty member blinded to whether they randomized to simulator training to re-assess their technical skills. The resident will have another proctored examination of simulator performance on the five tasks. Finally, a videotape review by independent observers will verify precision of the surgical evaluations at the conclusion of the study.
