Abstract

Background. Most robotic camera steering devices (RCSDs) require active steering by the surgeon and necessarily increase workload. Clinical experience shows that standard laparoscopic procedures can be performed safely as solo surgery aided by RCSDs. No evidence exists concerning exploratory or emergency procedures. We compared the performance during unexpected laparoscopic tasks on surgical simulators aided either by an RCSD controllable by head movements of the surgeon or by a human camera assistant. Methods. Forty-five medical students without previous experience with minimal invasive surgery were randomized in 2 groups, and they performed standard and unexpected laparoscopic tasks requiring complex camera movements on box trainers either using an RCSD or assisted by a human camera assistant. Efficiency and performance parameters were recorded. Results. Performance in simulated standard procedures was equivalent. In simulated exploratory procedures, we saw significantly better performance scores in the conventional group versus the RCSD group. The strongest factor for these differences was the longer camera-adjusting time in the RCSD group versus the conventional group (PEG task = 208 +/- 51 seconds vs 170 +/- 36 seconds, P = .005;suture task = 563 +/- 126 seconds vs 454 +/- 201 seconds, P = .041). Conclusion. These results, obtained on surgical simulators, indicate that the solo approach to standard surgical tasks, facilitated by an RCSD controllable by head movements, can most likely be viewed as safe. Exploratory procedures with a relevant chance for complications or procedures that require rapid, often, or complex camera movements should rather be performed with a human camera assistant.
