Three-dimensional (3D) imaging in laparoscopic right hemicolectomy (LRH) did not significantly reduce operative time for experienced surgeons. However, 3D vision subjectively improved depth perception and reduced surgeon strain, especially in longer procedures.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Colorectal Surgery

Background:

  • Laparoscopic right hemicolectomy (LRH) is a standard procedure for right colon cancer.
  • Evaluating advanced imaging technologies like three-dimensional (3D) visualization is crucial for optimizing surgical performance.
  • Comparing two-dimensional (2D) and 3D systems in LRH addresses operative efficiency and surgeon ergonomics.

Purpose of the Study:

  • To determine if 3D imaging offers operative time advantages in LRH compared to 2D.
  • To assess if 3D visualization significantly reduces surgeon physical strain during LRH.
  • To evaluate surgeon's subjective experience with depth perception and strain in both 2D and 3D LRH.

Main Methods:

  • Retrospective analysis of 50 consecutive LRH procedures (25 with 3D, 25 with 2D) by a single experienced surgeon.

  • Component task analysis to compare execution times between 2D and 3D laparoscopic right hemicolectomy.
  • Subjective questionnaire assessing depth perception and surgical strain post-procedure.

    • Main Results:

    • No significant difference in overall operative time between 2D and 3D LRH groups.
    • A statistically significant difference (P < .05) was observed in the 'side-to-side ileotransverse anastomosis' task time.
    • Surgeons reported improved depth perception and reduced physical strain with the 3D system, particularly in longer surgeries.

    Conclusions:

    • For experienced surgeons, 3D imaging in LRH does not appear to shorten operative time compared to 2D.
    • 3D visualization subjectively enhances depth perception and decreases surgeon strain during laparoscopic procedures.
    • Further research is needed to evaluate 3D benefits for novice surgeons and its impact on perioperative complications.
