Performance of three-dimensional and ultra-high-definition (4K) technology in laparoscopic surgery: A systematic review and meta-analysis.

BACKGROUND

The technology in the field of laparoscopy is rapidly evolving and is primarily focussed on increasing the quality of image and depth perception in the form of 4K and three-dimensional (3D) technology. There has been no conclusion yet regarding the better technology.

METHODS

A systematic search was performed independently by two authors across MEDLINE, Google Scholar and Embase using the PRISMA guidelines. All randomised control trials comparing 3D and 4K technologies were included. Meta-analysis was conducted using random-effects statistics for time taken for different tasks across the studies.

RESULTS

The search strategy revealed a total of 1835 articles, out of which nine studies were included. Three studies showed no superiority of 3D over 4K, while the remaining six did. Meta-analysis for the time taken for peg transfer favoured 3D over 4K (overall effect: Z = 2.12; P = 0.03). Forest plots for time taken for suturing (Z = 1.3; P = 0.19) and knot tying (Z = 1.7; P = 0.09) also favoured 3D over 4K; the results however were statistically insignificant. Path length was reported by two studies and was found to be lesser in the 3D group. Two studies measured the workload by NASA/Surg-TLX score, which was lower in the 3D group. Visual side effects were found to be higher in the 3D group.

CONCLUSION

3D technology is likely to result in a shorter operative time and better efficiency of movement as compared to the 4K technology by the virtue of its better depth perception.
