Description
Summary:Background Unsteady camera movement and poor visualization contribute to a difficult learning curve for laparoscopic surgery. Remote-controlled camera holders (RCHs) aim to mitigate these factors and may be used to overcome barriers to learning. Our aim was to evaluate performance benefits to laparoscopic skill acquisition in novices using a RCH. Methods Novices were randomized into groups using a human camera assistant (HCA) or the FreeHand v1.0 RCH and trained in the (E-BLUS) curriculum. After completing training, a surgical workload questionnaire (SURG-TLX) was issued to participants. Results Forty volunteers naïve in laparoscopic skill were randomized into control and intervention groups ( n  = 20) with intention-to-treat analysis. Each participant received up to 10 training sessions using the E-BLUS curriculum. Competency was reached in the peg transfer task in 5.5 and 7.6 sessions for the ACH and HCA groups, respectively ( P  = 0.015), and 3.6 and 6.8 sessions for the laparoscopic suturing task ( P  = 0.0004). No significance differences were achieved in the circle cutting ( P  = 0.18) or needle guidance tasks ( P  = 0.32). The RCH group experienced significantly lower workload ( P  = 0.014) due to lower levels of distraction ( P  = 0.047). Conclusions Remote-controlled camera holders have demonstrated the potential to significantly benefit intra-operative performance and surgical experience where camera movement is minimal. Future high-quality studies are needed to evaluate RCHs in clinical practice. Trial registration ISRCTN 83733979
