The aim of this study is to determine if there is a benefit in intra‐operative efficiency when using a 3D visualization system in difficult LC compared to traditional 2D visualization systems.MethodsRetrospective analysis of ‘difficult’ LCs (Grades 3 or 4) was completed. The assessor was blinded as all cases were recorded and viewed in 2D only. Variables collected included time to complete steps, missed hook diathermy attempts, failed grasp attempts, missed clip attempts and preparation steps for intra‐operative cholangiogram (IOC). Multiple linear regression was undertaken for time variables, Poisson regression or negative binomial regression was completed for continuous variables.ResultsFifty‐two operative videos of ‘difficult’ LC were reviewed. 3D systems were associated with reduced operative times, although this was not statistically significant (CI: −2.93–14.93, P‐value = 0.183). Dissection of the anterior fold to achieve the critical view of safety was significantly faster by 3.55 min (CI: 1.215–9.206, P‐value = 0.002), and with considerably fewer errors when using 3D systems. Fewer IOC preparation errors were observed with a 3D system compared with a 2D system.Conclusions3D systems appear to enhance operator efficiency, allowing faster completion of critical steps with fewer errors. This pilot study underscores the utility of video annotation for intra‐operative assessment and suggests that, in larger multi‐centre studies, 3D systems may demonstrate superior intra‐operative efficiency over 2D systems during a ‘difficult’ LC. 10.1111/ans.18949 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
