Overview
This study compared the performance of 3-D and 2-D laparoscopic systems during Roux-en-Y gastric bypass procedures. Conducted in an academic tertiary care center, the research involved 50 operations performed by the same surgical team. The results showed that the use of 3-D laparoscopic systems was associated with significantly fewer errors and error-related events compared to 2-D systems. Additionally, technical skill scores were notably higher when using the 3-D system.
The findings suggest that 3-D laparoscopic systems may offer important advantages in terms of surgical precision and safety. By providing better depth perception and spatial orientation, these systems appear to enhance surgeons' technical performance. However, the study acknowledges its limited sample size, indicating that further research may be needed to confirm these results across a broader range of procedures and surgical teams.
Results
Of the 50 patients who underwent LRYGB procedures, 42 (86%) were women, with a median (interquartile range) age of 42 (35-47) years and a median (interquartile range) body mass index of 46 (42-48), with no significant demographic differences between the groups whose operations were performed using the 2-D and 3-D systems. The mean (SD) number of errors per case was significantly lower in procedures using the 3-D laparoscopic system than in those using the 2-D system (17 [6] vs 33 [2]; P < .001). The mean (SD) number of error-related events was significantly lower in procedures using the 3-D system than in those using the 2-D system (6 [2] vs 11 [4]; P < .001). Mean (SD) Objective Structured Assessment of Technical Skill scores were significantly higher when the 3-D system was used than when the 2-D system was used (28 [4] vs 22 [3]; P < .001).
