The effect of different single ports on performance in single-incision laparoscopic surgery
Aims: In the rapidly advancing world of laparoendoscopic surgery, surgeons are faced with new devices all of which are aimed towards a single access. Various single-access devices are available on the market. Our study aimed to compare the performance of experienced laparoscopic surgeons on validated laparoscopic tasks using five devices within a simulation setting.
Methods: Ten experienced consultant laparoscopic surgeons were recruited after completing a questionnaire and meeting the inclusion criteria of the study. Five different single-access devices were assessed. Each participant performed two validated laparoscopic simulation tasks: peg transfer and pattern cut. All surgeons completed both tasks on all five devices in a randomized order. The performance time and the number of errors and instrument clashes on each task were measured. Statistical analysis was carried out using one-way analysis of variance.
Results: All participants were consultant laparoscopic surgeons with 4–20 years of experience with laparoscopy and fulfilled the selection criteria. One-way analysis of variance revealed no statistically significant differences in performance time (peg transfer, P = 0.306; pattern cut, P = 0.819), number of errors (peg transfer, P = 0.182; pattern cut, P = 0.478) or instrument clashes (peg transfer, P = 0.446; pattern cut, P = 0.061) between the different singe-access devices.
Conclusion: In our study, the laparoscopy experts performed equally well on all five single-access devices within a validated simulation environment. More and larger studies in simulated as well as clinical environments are required to provide further evidence.
