Plain English Summary
Background and study aims
In keyhole (laparoscopic) surgery, the aim is to avoid making large openings in a patient's body. The surgeons insert a camera and thin tools into small holes to view the inside of the patient's body and perform the surgery. The aim of this research is to find out whether trainee surgeons can perform keyhole (laparoscopic) surgery techniques more quickly if a robot holds the camera rather than a human. The robotic holder might provide a more steady camera image.
Who can participate?
Trainee surgeons who are following the European School of Urology's training curriculum, European training in Basic Laparoscopic Urological Skills (E-BLUS). Students with previous experience of laparoscopic skills will be excluded from the study.
What does the study involve?
Trainees will be randomly allocated to the robot or human camera holder and will carry out the practice surgery tasks in a simulated set-up. The time taken to complete the tasks will be recorded.
What are the possible benefits and risks of participating?
Participants will benefit from this trial in improving their keyhole surgery skills. They may experience stress and fatigue due to the demands of surgical training.
Where is the study run from?
The trial will take place at the Sherman Education Centre, Guy’s Hospital, London.
When is the study starting and how long is it expected to run for?
December 2018 to June 2019
Who is funding the study?
FreeHand Surgeon (UK), the maker of the Freehand robotic holder system.

Evaluation of FreeHand camera holder on the learning curve for basic laparoscopic skills using the European training in basic laparoscopic urological skills (E-BLUS) validated curriculum
The Robotic Arm will make the learning curve steeper or remain the same compared with conventional methods.

Participants will be recruited on a voluntary basis. An open invitation will be sent out to medical students at King’s College London. This invitation will be issued via GKT Medical School Association newsletters, Facebook group pages e.g. KCL Surgical and KCL Urological societies, and word of mouth. Students will have to sign up via an online form. Students with previous experience of laparoscopic skills will be excluded from the study.
Two cohorts will be created via randomization: Control (conventional human assistant) and Intervention (FreeArm robotic laparoscopic holder). Each cohort will have 20 students. They will complete the four trials of the EBLUS curriculum: peg transfer, cutting a circle, needle guidance, laparoscopic suturing.
After enrollment participants are invited to an orientation session to help them understand the basics of keyhole surgery and equipment. Inductions sessions are 2 hours in length. After this participants are invited to attend training sessions at our simulation laboratory where they will conduct basic keyhole surgery tasks on simulators. Training consists of 10 sessions with each session lasting between 1-3 hours depending on how long they take to complete the tasks. Both cohorts are are assessed by the time it takes for them to successfully complete the task; this is done by a stopwatch. Participants from the two cohorts are free to attend training sessions as and when it suits them.
