Brief summary

Robotic surgery holds the potential to overcome many of the ergonomic challenges posed by laparoscopic surgery. In this study, we propose to quantify this potential ergonomic benefit by measuring electromyography (EMG) and instrument motion analysis of subjects performing surgical tasks using robotic assistance versus standard laparoscopic instrumentation. Hypothesis: We hypothesize that surgeons will experience significant, measurable ergonomic advantages when performing tasks using robotic surgery when compared to conventional laparoscopic tools. Study design: Subjects for the study will include three groups of varying degrees of training - (1) novice laparoscopists/novice roboticists, (2) expert laparoscopists/novice roboticists, and (3) expert laparoscopsts/expert roboticists. Subjects will perform the following tasks (chosen based on their reliability and validity in previous studies). Each task will be performed with standard laparoscopic instrumentation and with the da Vinci Surgical System. * Inanimate (dry lab): Fundamentals of Laparoscopic (FLS) peg transfer, pattern cutting, intracorporeal suturing. * Animate (porcine lab): laparoscopic bowel resection and anastomosis, robotic bowel resection and anastomosis. * Human (clinical case): any laparoscopic or robotic procedure (preferably laparoscopic bowel resection and anastomosis, robotic bowel resection and anastomosis). Outcome measures: * Time to completion of tasks * EMG: peak amplitudes, % maximum voluntary contraction and frequency analysis * NASA Task Load Index scores * Subject-Reported Qualitative Data from surveys * Quality analysis of tasks (e.g., pattern cutting accuracy, % knots tied securely) for dry lab and animate lab tasks only) * Instrument motion analysis of tasks (for dry lab and animate lab tasks only)
